The aim of the study was to establish the pattern of the agouti pelvis by obtaining external and radiographic internal pelvimetric values. Forty-three agouti (Dasyprocta prymnolopha), females and males bred in under human care were used. The parameters measured were the external biiliac diameter; the external biischiatic diameter; right and left external ilioischiatic diameters and radiographic internal measurements (true conjugated, the diagonal conjugated; the vertical, the sacral, sagittal, coxal tuberosity, upper biiliac, lower biiliac, and biischiatic diameter. The inlet pelvic area and the outlet pelvic area were calculated, as well the height/width ratios of the entrance area of the pelvis and the pelvic outlet area were calculated. The mean values for each body measurement of females and males were: weight 1.91kg and 2.04kg, external biiliac diameter 6.32cm and 6.30cm, external biischiatic diameter 4.34cm and 4.28cm, right external ilioischiatic diameter 9.01cm and 9.33cm, left external ilioischiatic diameter 9.13cm and 9.30cm, true conjugated 3.90cm and 3.68cm, diagonal conjugated 7.13cm and 6.91cm, vertical diameter 2.59cm and 2.45cm, sacral diameter 2.63cm and 2.44cm, sagittal diameter 3.30cm and 3.09cm, coxal tuberosity diameter 2.52cm and 2.43cm, upper biiliac diameter 6.28cm and 6.24cm, lower biiliac diameter 2.98cm and 2.58cm, biischiatic diameter 2.60cm and 2.70cm, height/width ratio - vertical/ lower biiliac diameter 0.88cm and 0.95cm, sagital/coxal tuberosity diameter 1.32cm and 1.28cm, inlet pelvic area 82.38cm and 77.83cm and outlet pelvic area 24.76cm and 20.07cm. Agouti are dolichopelvic animals, demonstrating the existence of a discrete sexual dimorphism in adults and low intensity correlations between the external and internal measures studied.

O objetivo deste estudo foi estabelecer o padrão da pelve de cutia, masculina e feminina, por meio da obtenção dos valores médios da pelvimetria externa e interna radiográfica.

Calcific tendinitis is a pathology characterized by the deposits of periarticular hydroxyapatite. Its pathophysiology is not completely known. It is clinically characterized by important inflammatory changes with incapacitating pain. It most commonly affects the shoulder joint and it rarely affects the hand and wrist. Given the unusual nature of this localization, we present the clinical case of a woman who developed calcific tendinitis of the third metacarpophalangeal muscle. We present the clinical evolution of the case, the treatments carried out, and a review of the literature related to this unusual localization of calcific tendinitis.

Zenker's diverticulum develops in the hypopharynx, usually between the cricopharyngeus muscle and the inferior pharyngeal constrictor muscle, at the level of the C5 and C6 vertebrae. It often manifests clinically with dysphagia, persistent reflux, and halitosis. Its reference diagnosis is through barium video swallowing observed by fluoroscopy. Management is surgical with a cervical or transoral approach, the latter having a better safety profile

Introduction: Body piercings consist of small holes made with a needle in different parts of the skin or body to introduce a jewel or decorative element. In the oral cavity, most piercings are placed in the tongue. However, some complications may occur, and surgical techniques must be used for their removal. These complications present a certain degree of difficulty due to their position and may challenge the ability of the clinician to access the specific anatomical location. The different imaging techniques, from simple radiography to intraoperative techniques such as image intensifiers, have become an extremely useful tool for locating an object in the three dimensions of space, allowing safe location and extraction. Objective: The aim of this study is to report the case of a complication of a body piercing in the oral cavity and how the use of imaging was decisive for surgical planning and for the quick and effective resolution of the case. Material and Methods: A 14-year-old female patient came looking for treatment. Her mother reported the onset of the condition after the insertion of a needle-like metallic object while performing an artistic perforation in the lingual region. Since the girl was unable to extract the object, she sought medical advice at the Carlos Arvelo Military Hospital in Caracas, Venezuela. Subsequently, an imaging study was performed by means of a Computed Tomography to locate the metallic object. It was observed that the foreign body had migrated to the floor of the mouth/sublingual region, requiring the area to be surgically approached. It was also decided to use an intraoperative image intensifier. The removal of the object was performed satisfactorily. Conclusion: The extraction of foreign bodies placed in the lingual and sublingual region represents a challenge for the clinician due to the number of important anatomical structures that pass through that area. This makes clinicians plan their surgical removal using pre- and intraoperative imaging, to find a less traumatic location, reduce surgical time as well as the risk of damaging adjacent anatomical structures.

Introducción: Los body piercings consisten en producir perforaciones con una aguja en diferentes localizaciones de la piel con el fin de introducir una joya o elemento decorativo a través del agujero producido previamente. En la cavidad oral, la lengua es el sitio de mayor elección; sin embargo, en ciertas ocasiones suelen presentarse ciertas complicaciones, por lo cual se debe recurrir a técnicas quirúrgicas para su remoción presentando cierto grado de dificultad para su localización y la capacidad del clínico para acceder al espacio anatómico. Las diferentes técnicas imagenológicas desde una radiografía simple hasta técnicas intraoperatorias como los intensificadores de imágenes se han convertido en una herramienta sumamente útil para la ubicación de un objeto en las tres dimensiones del espacio, permitiendo una localización y extracción segura para el clínico y el paciente. Objetivo: El propósito de este trabajo es reportar un caso de una complicación de esta práctica en la región bucal y cómo el uso de la imagenología fue determinante para la planificación quirúrgica y la resolución del caso de manera rápida y efectiva. Material y Métodos: Se presenta a consulta una paciente femenina de 14 años de edad, quien madre refiere inicio de enfermedad actual posterior a introducirse objeto metálico tipo aguja de compás con la finalidad de realizar perforación artística en región lingual, al no poder extraer dicho objeto, acude a evaluación en el Hospital Militar Carlos arvelo de Caracas; posterior se realiza estudio imagenológico tipo Tomografía Computarizada para la ubicación del objeto metálico donde se observa que el cuerpo extraño habría migrado hacia el piso de boca/región sublingual, teniendo la necesidad de abordar quirúrgicamente la zona y elegir el uso de intensificador de imagen transoperatorio para retiro del mismo el cual se dio de manera satisfactoria. Conclusión: Los cuerpos extraños desplazados a la región lingual y sublingual representan un desafío para el clínico al momento de extraerlos, esto se debe a la cantidad de estructuras anatómicas importantes que pasan por dicha zona, lo que hace que el clínico opte en su planificación quirúrgica por el uso de imagenología pre y transoperatoria obteniendo así una localización menos traumática, menor tiempo operatorio y menor riesgo de lesión de estructuras anatómicas adyacentes.

Las fracturas con hundimiento de cráneo intrauterinas representan una entidad poco frecuente, generalmente secundaria a traumatismos (previos o durante el nacimiento) o de etiología desconocida. Suelen requerir evaluación y seguimiento por el servicio de Neurocirugía Pediátrica. A la fecha, es controversial la necesidad de tratamiento quirúrgico y el momento oportuno para concretarlo. Se presentan dos casos clínicos de pacientes de término, nacidas porcesárea,condiagnósticoposnatalinmediatodehundimiento de cráneo de tipo ping-pong no traumático. Ambas pacientes presentaron examen neurológico normal. Se confirmó el diagnóstico a través de radiografía y tomografía de cráneo, sin observarse lesiones asociadas. Fueron valoradas por el servicio de Neurocirugía, que indicó corrección quirúrgica de la lesión en ambos casos, con buena evolución posterior.

Spontaneous intrauterine depressed skull fractures are a rare entity. They can appear secondarily to head trauma (before or during birth) or due to unknown etiology. They usually require a complete evaluation from pediatric neurosurgery specialists. Their optimal management, including timely surgical treatment remains controversial. We describe two cases delivered by cesarean section, with postnatal diagnosis of spontaneous intrauterine depressed skull fracture. Both had a normal neurological exam. A skull radiography and head CT were performed, and no associated lesions were found. Both cases required surgical correction, with positive results.

Virtual learning environments (VLEs) have numerous possibilities for the use of their tools and can assist in the processesof teaching and learning aboutthe radiographic image interpretation. This study aimed to evaluate the use of a virtual learning environment as a support material for students in the discipline of Dental Radiology.This radiographic interpretation was conducted to contribute to the knowledge and training of the changes in the tooth andadjacent bone tissue,visualized in periapical and interproximal radiographs. The scores of the virtual test (via the Moodle platform) and the interpretation test (in the classroom) were used to compare Group Number 1 (students thatperformed the virtual test before the classroom test) and Group Number 2 (students thatperformed the virtual test after the classroom test). It was observed that,in general, the mean score of the interpretation test was higher than the virtual.Also,66% of the students used the platform as the main resourceto follow the discipline, due to the possibility of reviewing the contents andactivities. The virtual learning environment can be considered an important complementary sourcefor teaching radiographic interpretation. The Moodle platform acts as a remarkable tool, with the potential capacity to support the teaching and learning process. For this, mutual collaboration among students, University,and educational institution isnecessarily required for the constant use, maintenance,and updating of the virtual environment (AU).

Os ambientes virtuais de aprendizagem (AVA) possuem inúmeras possibilidades de utilização de suas ferramentas e podem auxiliar nos processos de ensino e aprendizagem sobre a interpretação de imagens radiográficas. Este estudo teve como objetivo avaliar a utilização de um ambiente virtual de aprendizagem como material de apoio para alunos da disciplina de Radiologia Odontológica. Essa interpretação radiográfica foi realizada para contribuir com o conhecimento e treinamento das alterações no órgão dentário e tecido ósseo adjacente, visualizadas em radiografias periapicais e interproximais. As notas da prova virtual (via plataforma Moodle) e da prova de interpretação (em sala de aula) foram utilizadas para comparar o Grupo Número 1 (alunos que realizaram a prova virtual antes da prova presencial) e o Grupo Número 2 (alunos que realizaram a prova virtual, após o teste em sala de aula). Observou-se que, em geral, a média da prova de interpretação foi superior à da prova virtual. Além disso, 66% dos alunos utilizaram a plataforma como principal recurso para acompanhar a disciplina, devido à possibilidade de revisão dos conteúdos e atividades. O ambiente virtual de aprendizagem pode ser considerado uma importante fonte complementar para o ensino da interpretação radiográfica. A plataforma Moodle atua como uma ferramenta notável, com potencial capacidade de apoiar o processo de ensino e aprendizagem. Para isso, é necessária a colaboração mútua entre alunos, Universidade e instituição de ensino para a constante utilização, manutenção e atualização do ambiente virtual (AU).

Se presenta el caso de una paciente de 56 años, quien consulta por dolor torácico lateral izquierdo de dos días de evolución y en su radiografía de tórax tomada en preoperatorio de nódulo tiroideo aparece una pequeña banda de atelectasia plana basal izquierda. Por persistencia del dolor en el posoperatorio tardío, se realizan estudios de ultrasonido, gammagrafía ósea, TAC de tórax y RNM de tórax, encontrándose finalmente un elastofibroma dorsi como causa del dolor a partir de los estudios realizados. El elastofibroma dorsi es una entidad relativamente rara, de patogénesis desconocida, que requiere de sospecha clínica para su diagnóstico. Las imágenes pueden comprobar el diagnóstico sin requerir biopsia. La resección es necesaria por crecimiento de la lesión o dolor persistente. Se revisa la literatura pertinente.

Here we present a case of a 56-year-old female patient, who consulted for presenting left lateral chest pain of 2 days of evolution, and in her chest X-ray taken preoperatively for a thyroid nodule, a small band of flat left basal atelectasis appears. Due to persistent pain in the late postoperative period, thoracic ultrasound, bone scan, chest CT, and chest MRI studies were performed, finally finding an elastofibroma dorsi as the cause of the pain. The studies carried out are shown. Elastofibroma dorsi is a relatively rare entity of unknown pathogenesis that requires clinical suspicion for its diagnosis. Imaging can confirm the diagnosis without requiring a biopsy. Resection is necessary due to growth of the lesion or persistent pain. Relevant literature is reviewed.

Introducción: durante la pandemia por COVID-19, la radiografía portátil de tórax y la ultrasonografía se han usado ampliamente para el seguimiento de pacientes hospitalizados. Sin embargo, es escasa la información sobre la relación entre los signos que se observan mediante cada método en pacientes con COVID-19. Objetivo: estimar la correlación entre imágenes concurrentes obtenidas por ultrasonografía de pulmón y por radiografía portátil de tórax durante el seguimiento de pacientes hospitalizados por COVID-19. Material y métodos: se realizaron 113 estudios de ultrasonografía y los correspondientes 113 de radiografía portátil de tórax durante el seguimiento de 44 pacientes (30 hombres/14 mujeres, edad 30-85 años) con COVID-19 (RT-qPCR). Las imágenes se resguardaron en un sistema de comunicación para su evaluación independiente por dos especialistas en cada método. El análisis se hizo con correlación gamma y prueba t (significancia de 0.05). Resultados: el signo por ultrasonido más frecuente fue el de líneas B-confluentes en correlación con los signos radiológicos de imagen en vidrio deslustrado y consolidación. Se observó correlación inversa entre líneas A (pulmón aireado) y líneas B7 (sugerentes de edema intersticial); las líneas B-confluentes mostraron correlación inversa y fuerte con líneas A (a mayor frecuencia de líneas B-confluentes, menor frecuencia de líneas A), correlación inversa moderada con líneas B7 y correlación inversa débil con líneas B3. Conclusión: en el seguimiento de pacientes hospitalizados por COVID-19, los signos por ultrasonografía pulmonar y por radiografía portátil de tórax pueden ser complementarios para identificar las características del daño pulmonar

Background: During the COVID-19 pandemic, portable chest radiography (portable CRx) and lung ultrasonography (LUS) have been widely used to follow up hospitalized patients. Yet, it is scarce the information about the relation between the signs observed by means of each method in patients with COVID-19. Objective: To assess the correlation between concurrent images acquired by LUS and portable CRx during the follow-up of hospitalized patients with COVID-19. Material and methods: We performed 113 LUS and 113 corresponding CRx during the follow-up of 44 patients (30 men/14 women, 30-85 years old) with COVID-19 (RT-qPCR). Images were stored in a picture communication system and were revised by two specialists of each imaging method independently. Statistical analysis was performed using Gamma correlation and t test (significance level of 0.05). Results: The most frequent LUS sign was confluent B lines, and it was related to the most frequent portable CRx signs (ground-glass opacities and consolidations). An inverse relationship was observed between A lines (gas in the lungs) and B7 lines (suggestive of interstitial edema). Confluent B lines also showed a strong inverse correlation with A lines (more frequent confluent B lines were related to low frequent A lines), a moderate inverse correlation with B7 lines, and a mild inverse correlation with B3 lines. Conclusion: During the follow-up of hospitalized patients with COVID-19, LUS and portable CRx may complement each other to provide information about lung damage

Shoulder fracture is one of the most frequently treated injuries in trauma centers, with an overall incidence that appears to have increased in recent years, ranging from 219 to 419 cases per 100 000 person-years. In clinical terms, shoulder girdle injury is difficult to diagnose due to the close relationship between the shoulder and the chest, and imaging identification of the different types of injuries can be challenging. In this context, X-rays are the most appropriate method and the cornerstone of the initial approach to shoulder trauma, and at least 3 views are recommended: true anteroposterior view (AP), axial or axillary projection or modified axial projection (Velpeau view), and lateral scapula shoulder or Y view. However, patient positioning is often problematic due to the additional pain associated with limb mobilization in order to achieve the proper position for radiographic projection. The following is the description of a technique for performing an axial shoulder projection that is free of these complications, easy to standardize, and applicable to any traumatic or degenerative disease of the proximal humerus or glenohumeral joint, which, to the best of the authors' knowledge, has not been previously published.

El trauma de hombro es una de las patologías más frecuentemente vista en los centros de trauma con una incidencia global que aparentemente ha aumentado en los últimos años y que se ha reportado entre 219 a 419 casos por 100000 personas-año. El diagnóstico del trauma de la cintura escapular no es fácil clínicamente por la íntima relación entre el hombro y el tórax, y la identificación imagenológica de las distintas lesiones puede ser desafiante. Las radiografías son el método más apropiado y piedra angular del estudio inicial en el trauma de hombro, el set de trauma tiene al menos 3 planos: la vista Anteroposterior (AP) verdadera, una proyección axial o axilar o su modificación descrita por Velpeau. Y una proyección Y de escápula. Sin embargo, el posicionamiento del paciente muchas veces no es fácil por el dolor adicional que puede generar la movilización de la extremidad para lograr la posición adecuada para la proyección radiográfica. Describimos una técnica para realizar una proyección axial de hombro sin estas dificultades, fácilmente estandarizable para cualquier patología traumática o degenerativa del húmero proximal o de la articulación gleno-humeral y que creemos no ha sido publicada previamente.

OBJECTIVE@#To evaluate the clinical effect of root canal obturation therapy using cold flowable gutta-percha on young permanent teeth after apexification.@*METHODS@#Ninety cases of young permanent teeth with pulp necrosis or periapical periodontitis treated by apexification were randomly divided into two groups. The cases in each group were divided into single root canal and multiple root canal according to the number of the root canal, and divided into classifications Ⅰ, and Ⅱ/Ⅲ/Ⅳ according to Frank's classification of root development after apexification. Cold flowable gutta-percha and warm gutta-percha obturation techniques were used for root canal obturation of the two groups. The operation time was recorded, and the patients' therapy pain degree was evaluated by visual analog scale (VAS) immediately after operation. Periapical X-ray was performed after operation to evaluate the effect of the root canal filling. The total length of the root was divided into equal three parts on the X-ray film, and three-dimensional tightness of the apical, middle, and coronal region of the root canals were statistically analyzed respectively. Clinical examinations and X-ray examination were performed 6 and 12 months after the operation to evaluate the treatment success rate.@*RESULTS@#The operation time of cold flowable gutta-percha group was significantly lower than that of the control group, which were 51 s and 74 s (P < 0.05); The percentages of pain and discomfort in the two groups were 26.67% and 40.00%, respectively. There were two cases of underfilling and no overfilling in both groups. The percentages of proper filling and tight three-dimensional obturation in the experimental and control groups were 71.11% and 60.00% respectively; and the percentages of tight three-dimensional obturation in the apical third areas were 86.67% and 66.67%, the difference was significant (P < 0.05). There was no significant difference in the three-dimensional tightness between the two groups in the middle and coronal third areas. The percentages of tight three-dimensional obturation in classification Ⅰ groups were 86.67%, 83.33%, 93.33% and 76.67%, 90.00%, 96.67% in experimental and control group, respectively; The percentages of classification Ⅱ/Ⅲ/Ⅳ groups were 86.67%, 86.67%, 100.00% and 46.67%, 86.67%, 100.00%, respectively, and the difference was significant (P < 0.05). There were no apical lesions that occurred in either group during the one-year review period.@*CONCLUSION@#The application of cold flowable gutta-percha on young permanent teeth root canal obturation after apexification can achieve good obturation effect. The root obturation effect in the apical third area is significantly better than that of warm gutta-percha obturation techniques. Cold flowable gutta-percha can shorten the clinical treatment time and ameliorate the patients' therapy comfort.

OBJECTIVE@#To investigate the correlation between the changes of cervical curvature and atlantoaxial instability.@*METHODS@#The correlation between the changes of cervical curvature and atlantoaxial instability was retrospectively studied in 50 outpatients with abnormal cervical curvature (abnormal cervical curvature group) from January 2018 to December 2019. There were 24 males and 26 females in abnormal cervical curvature group, aged from 18 to 42 years old with an average of(30.62±5.83) years. And 53 patients with normal cervical curvature (normal cervical curvature group) during the same period were matched, including 23 males and 30 females, aged from 21 to 44 years with an average of(31.98±6.11) years. Cervical spine X-ray films of 103 patients were taken in lateral position and open mouth position. Cervical curvature and variance of bilateral lateral atlanto-dental space(VBLADS) were measured and recorded, Pearson correlation coefficient analysis was used to study the correlation between the changes of cervical curvature and atlantoaxial instability.@*RESULTS@#Atlantoaxial joint instability accounted for 39.6%(21/53) in normal cervical curvature group and 84.0%(42/50) in abnormal cervical curvature group. There was significant difference between two groups(P<0.01). VBLADS in abnormal cervical curvature group was (1.79±1.01) mm, which was significantly higher than that in normal cervical curvature group(0.55±0.75) mm(P<0.01). Pearson correlation coefficient analysis showed that the size of cervical curvature was negatively correlated with VBLADS.@*CONCLUSION@#Cervical curvature straightening and inverse arch are the cause of atlantoaxial instability, the smaller the cervical curvature, the more serious the atlantoaxial instability.

OBJECTIVE@#To investigate the method and clinical effect of modified Chevron osteotomy of the distal end of the first metatarsal in the treatment of moderate and severe hallux valgus.@*METHODS@#From January 2015 to January 2019, 28 patients(30 feet) with moderate and severe hallux valgus were treated with modified Chevron osteotomy combined with lateral soft tissue release of the first metatarsophalangeal joint, including 2 males (2 feet) and 26 females (28 feet). The age ranged from 35 to 74 (57.3±9.3) years;10 feet on the left, 16 feet on the right, 2 cases on both sides(4 feet);the course of disease was 3 to 12 (9.32±3.89) years. The changes of hallux valgus angle(HVA), intermetatarsal angle(IMA) between the first and second metatarsals and distal metatarsal articular angle(DMAA) of the first metatarsal were measured and compared before and 6 months after operation. The American Orthopaedic Foot and Ankle Society(AOFAS) thumb joint scoring system was used to evaluate the curative effect.@*RESULTS@#All 28 patients were followed up for 8 to 16 (11.28±3.42) months. The incision healed well in all patients, and there were no complications such as incision infection and metatarsal head necrosis. The healing time of osteotomy site was 6 to 10(7.12±1.34) weeks. Preoperative HVA, IMA, DMAA and AOFAS were (36.06±6.02) °, (21.78±4.16) °, (8.21±2.65) ° and (52.90±10.97) respectively, at six months after operation, they were (8.87±2.46) °, (11.66±2.84) °, (3.65±1.00) ° and (87.45±10.55) respectively, there was significant difference between preoperative and 6 months after operation(P<0.05). At 6 months after operation, AOFAS score was excellent in 20 feet, good in 7 feet and poor in 3 feet. Among the 3 patients with poor scores, 2 were excellent after revision, and 1 was significantly improved after using custom insoles.@*CONCLUSION@#Modified Chevron can effectively correct HVA, IMA and DMAA and improve functional recovery. The modified Chevron osteotomy increases the moving distance and the contact of the osteotomy surface. It can be fixed with multiple screws, has strong correction ability, and can exercise early. It is one of the optional methods for the treatment of moderate and severe hallux valgus.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the subsequent global outbreak (coronavirus disease 2019 [COVID-19]) was declared a public health emergency in January 2020. Recent radiologic literature regarding COVID-19 has primarily focused on Computed Tomography (CT) chest findings, with chest radiography lacking in comparison. Objectives: To describe the demographic profile of adult patients with COVID-19 pneumonia requiring hospital admission. To describe and quantify the imaging spectrum on chest radiography using a severity index, and to correlate the severity of disease with prognosis. Method: Retrospective review of chest radiographs and laboratory records in patients admitted to a South African tertiary hospital with confirmed COVID-19 infection. The chest X-rays were systematically reviewed for several radiographic features, which were then quantified using the Brixia scoring system, and correlated to the patient's outcome. Results: A total of 175 patients (mean age: 53.34 years) admitted with COVID-19 were included. Ground glass opacification (98.9%), consolidation (86.3%), and pleural effusion (29.1%) was commonly found. Involvement of bilateral lung fields (96.6%) with no zonal predominance (61.7%), was most prevalent. Correlation between the Brixia score and outcome was found between severe disease and death (odds ratio [OR]: 12.86; 95% confidence interval [CI]: 1.58­104.61). Many patients had unknown TB (71.4%) and HIV (72.6%) statuses. Conclusion: In this study population, ground glass opacification, consolidation, and pleural effusions, with bilateral lung involvement and no zonal predominance were the most prevalent findings in proven COVID-19 infection. Quantification using the Brixia scoring system may assist with timeous assessment of disease severity in COVID-19 positive patients, as an overall predicator of clinical outcome.

RESUMO O pectus excavatum é considerado uma patologia da parede torácica, onde há convexidade no aspecto ventral do esterno, o que gera complicações secundárias, como alongamento ventrodorsal do tórax e aumento da pressão intratorácica, entre outras. No presente caso, o corpo de um cachorro Buldogue Francês nasceu com sinais prévios de decaimento e baixo consumo de leito materno, além de uma avaliação médica forense. De acordo com a avaliação patológica, foi encontrada uma fenda no peito esternal relacionada às esternas caudais próximas à cartilagem xifóide, conteúdo espumoso na cartilagem epiglótica da laringe e sinais graves de enfisema nos lobos caudal, craniano e médio pulmonar. Na avaliação cardiológica, foi observada assimetria morfológica invaginante no septo interventricular na mesma área em que a fenda esternal ocorre, por sua vez, na avaliação radiográfica, evidencia uma depressão dorsal do terço caudal do esterno com alterações consideráveis na silhueta cardíaca. Na Colômbia não há relatos de ninhadas completas que apresentem esta alteração, portanto, pretende-se que este seja o primeiro relatório anatomopatológico e de imagem que descreva a patologia em caninos.

ABSTRACT Pectus excavatum is considered a pathology of the chest wall where there is convexity in the ventral aspect of the sternum, which generates secondary complications, such as ventrodorsal stretching of the chest and increased intrathoracic pressure, among others. In the present case, the body of a French bulldog dog was born with previous signs of decay and low consumption of maternal waste, in addition to a forensic medical evaluation. According to the pathological evaluation, a crack was found in the sternal chest related to the caudal sternum close to the xiphoid cartilage, frothy content in the laryngeal epiglottis cartilage and severe signs of emphysema in the caudal, cranial and middle lung lobes. In the cardiological evaluation, an invaginating morphological asymmetry was observed in the interventricular septum in the same area in which the sternal cleft occurs, in turn, in the radiographic evaluation, it shows a dorsal depression of the caudal third of the sternum with considerable changes in the cardiac silhouette. In Colombia there are no reports of complete litters that present this alteration, so it is intended that this is the first anatomopathological and imaging report that describes the pathology in canines.
