ABSTRACT

ABSTRACT A 2-year-old female patient, admitted in the emergency room, presented diarrhea for 5 days and bloody stools in the last 24 hours. Physical examination revealed no significant findings. Ultrasound was initially performed, showing an elongated, well delimited and solid mass occupying since right hypocondrium until left iliac fossa, displacing adjacent structures. In sequence, magnetic resonance imaging was performed for confirmation of findings suggestive of omentum lipoma. After 1 week, the surgical resection was performed by videolaparoscopic acess. During 2-year follow-up, there was no sign of recurrence.

ABSTRACT

Tumores cardíacos primários consistem em patologia rara, sendo encontrados em até 0,03% das autópsias e a maioria benigna. Dentre os benignos, os lipomas apresentam incidência de 8,5%, localizando-se mais frequentemente no septo interatrial. Quando localizado no septo interventricular, é considerado patologia ainda mais incomum, com prevalência real desconhecida. Na maioria dos casos, o diagnóstico ocorre de forma incidental, por exame de imagem cardiovascular, e pode ser confirmado por exame histopatológico. Apresentam-se mais comumente de forma assintomática ou com sintomas inespecíficos, mas podem evoluir com arritmias, disfunção valvar, insuficiência cardíaca e óbito, o que ressalta a importância dos métodos de imagem cardiovascular no diagnóstico diferencial e na orientação da terapêutica adequada. O presente trabalho relata o caso de um paciente com achado ecocardiográfico incidental de massa cardíaca localizada no septo interventricular, seguindo da realização de ressonância magnética cardíaca, para melhor caracterização da lesão e demonstração de características compatíveis com lipoma.(AU)

ABSTRACT

Los lipomas son tumores benignos compuestos por adipocitos maduros. Si bien representan la neoplasia más común en el cuerpo humano, su aparición en la región de la cabeza y el cuello es relativamente rara. No muestra predilección por sexo y afecta a individuos en la cuarta década de vida. Clínicamente, puede observarse un aumento de volumen nodular, de consistencia blanda y superficie lisa. Su etiopatogenia aún es desconocida, aunque algunos autores han sugerido factores endócrinos, inflamatorios, hereditarios y traumáticos. El diagnóstico se realiza a través de la evaluación clínica, con la ayuda de pruebas de imagen como la tomografía computarizada y la resonancia magnética. Sin embargo, solo puede ser confirmado mediante análisis histopatológico de la lesión, considerado el examen por excelencia. El tratamiento de los lipomas y todas sus variantes consiste en la extirpación quirúrgica total, con lo cual se disminuye la posibilidad de recidivas, que es rara de por sí. El objetivo de esta publicación es informar un caso clínico de lipoma localizado en la región de la mucosa yugal, con extirpación quirúrgica completa de la lesión de manera ambulatoria (AU)


Lipomas are benign tumors composed of mature adipo- cytes. Although they represent the most common neoplasia in the human body, their occurrence in the head and neck region is relatively rare. Regardless of gender, they affect individu- als from the fourth decade of life on. Clinically, an increase of the nodular volume with softened consistency and smooth surface can be observed. Although its etiopathogenesis is still uncertain, some authors have suggested endocrinal, inflam- matory, hereditary and traumatic factors. The diagnosis is made through clinical evaluation, with the aid of imaging ex- aminations, such as computerized tomography and magnetic resonance. However, it can only be confirmed through the histopathological analysis of the lesion, which is considered the gold standard examination. The treatment of the lipomas and all their variations consists of complete surgical exci- sion, thus diminishing the possibility of recurrence, which in turn is rare. The aim of this publication is to report a clin- ical case of lipoma, located in the jugal mucosa region and treated through complete surgical removal of the lesion on an outpatient basis (AU)

ABSTRACT

RESUMEN El lipoma intraóseo es un tumor mesenquimatoso poco frecuente que se presenta principalmente en el esqueleto apendicular. La localización dentro del cráneo, es aún más rara, y hasta la fecha solo se han descrito 6 casos en la literatura de lipomas intraóseos que comprometen la región esfenoclival. Por lo general, no presenta ningún síntoma y es un hallazgo incidental en el estudio de imágenes. Presentamos el caso de un paciente de 22 años de edad que consulta por obstrucción nasal y rinorrea mucosa de tres semanas de evolución. La tomografía computarizada y resonancia nuclear magnética evidenciaron una lesión en la región esfenoclival con características sugerentes de lipoma intraóseo. No se realiza estudio histopatológico. Con respecto al manejo, se decide hacer seguimiento radiológico. Se realizó una segunda resonancia magnética 4 meses después, sin cambios significativos.


ABSTRACT Intraosseous lipoma are a rare mesenchymal tumor that occurs primarily in the appendicular skeleton. Skull presentation is a rare finding, and only 6 cases have been described in literature so far of lipomas that compromise the sphenoclival region. In general, they are asymptomatic and occur as incidental findings in imaging studies. We present the case of a 22-year-old patient who consulted for nasal obstruction and mucous rhinorrhea of three weeks of evolution. Computed tomography and magnetic resonance imaging showed a lesion in the sphenoclival region suggestive of intraosseous lipoma. Histopathological study was not performed. Regarding management, radiological follow-up was decided. A second MRI was taken 4 months later, with no significant changes.

ABSTRACT

Dentro de las neoplasias más frecuentes de tejidos blandos mesenquimáticos, el lipoma es el de mayor frecuencia. A nivel de cabeza y cuello, su incidencia es inferior, siendo de 2 a 4 por ciento. En la cavidad bucal, la ubicación más usual es en la lengua. Histológicamente, se observan adipocitos separados por tabiques fibrosos. El diagnóstico diferencial se realiza con tumor de células granulares, neurofibroma, fibroma traumático y malformaciones de las glándulas salivales. En el siguiente artículo se describirá un caso clínico con su técnica quirúrgica.


Among the most frequent neoplasms of soft mesenchymal tissues, lipoma is the most frequent. At head and neck level, the incidence is lower, being 2 to 4 percent. In the oral cavity, the most usual location is on the tongue. Histologically, adipocytes are seen separated by fibrous septa. The differential diagnosis is made with granular cell tumor, neurofibroma, traumatic fibroma and malformations of the salivary glands. The following article will describe a clinical case with its surgical technique.

ABSTRACT

Intracranial lipomas are congenital, benign and slow-growing tumors. The incidence were 0.1 to 0.5 percent of all primary brain tumors and are often diagnosed in incidental findings of neuroradiological investigation. Lipoma in quadrigeminal region occurs in 25 percent of intracranial lipomas and has been reported as lipomas in quadrigeminal cistern (perimesencephalic cistern), quadrigeminal plate, ambiens cistern or superior medullary velum. MRI is the most major exam. The treatment is conservative in most cases, surgical removal is hampered by their deep location and contiguous with adjacent neurovascular structures. The authors report two cases of lipoma in the quadrigeminal region, incidental findings and discuss the clinical findings, neuroimaging and treatment.


Lipomas intracranianos são tumores congênito, benigno e de crescimento lento. Sua incidência é de 0.1 a 0.5 por cento de todos os tumores cerebrais primários e são frequentemente diagnosticados em achados incidental de investigação neuroradiológica. Lipoma na região quadrigeminal ocorre em 25 por cento dos lipomas intracranianos e tem sido relatados como lipomas na cisterna quadrigeminal (cisterna perimesencefálica), placa quadrigeminal, cisterna ambiens ou véu medular superior. O exame de eleição é ressonância magnética. O tratamento é conservador na maioria dos casos, a remoção cirúrgica é dificultada pela sua localização profunda e da contiguidade com estruturas neurovasculares adjacentes. Os autores relatam dois casos de lipoma na região quadrigeminal achados incidentalmente e discutem os achados clínicos, imagem e tratamento.

ABSTRACT

Abstract Onychogryphosis is an acquired nail plate change. It often affects the toenail and is characterized by an opaque, yellow-brownish nail plate that is distorted, grossly thickened, elongated, and partly curved resembling a ram's horn. Tuberous sclerosis complex is a multisystem disorder associated with high rates of mental retardation, autism, cognitive impairment, behavioral problems, or seizures. Nail disease can also be associated, which is a concern to patients due to pain and nail distortion. We reported a typical tuberous sclerosis complex patient with distinctive clinical features of a ram's horn nails, which presented a great challenge to surgical treatment and nail restoration.

ABSTRACT

We describe two cases of lipomatous endobronquial tumors diagnosed by CT. The first case showed a homogeneous fat density endobronquial nodule in the right intermediate bronchus compatible with lipoma. The second patient underwent a CT under the suspicion of a endobronquial lesion after two episodes of pneumonia localized in left lower lobe. The TC demonstrated a fat predominant nodule in the left lower lobe bronchus. The anatomopathologic study confirmed a lipomatous hamartoma with areas of mature cartilage.


. Describimos 2 casos de tumores lipomatosos endobronquiales diagnosticados mediante TC. El primer caso mostró un nódulo homogéneo de densidad grasa de 11 mm localizado en el bronquio intermediario derecho, que correspondió a un lipoma. El segundo paciente se sometió a una TC por la sospecha de lesión endobronquial luego que cursara con 2 episodios de neumonías localizadas en el lóbulo inferior izquierdo. En esta se demostró un nódulo de predominio graso con pequeñas áreas de densidad de partes blandas en el bronquio inferior izquierdo. El estudio patológico confirmó que se trataba de un hamartoma lipomatoso con áreas de cartílago maduro.

ABSTRACT

OBJECTIVE: To evaluate the value of enhancement features and quantitative parameters of contrast-enhanced ultrasonography (CEUS) in differentiating solid hypoechoic renal angiomyolipomas (AMLs) from clear cell renal cell carcinomas (ccRCCs). MATERIALS AND METHODS: We analyzed the enhancement features and quantitative parameters of CEUS in 174 hypoechoic renal masses (32 AMLs and 142 ccRCCs) included in the study. RESULTS: Centripetal enhancement pattern was more common in AMLs than in ccRCCs on CEUS (71.9% vs. 23.2%, p < 0.001). At peak enhancement, all AMLs showed homogeneous enhancement (100% in AML, 27.5% in ccRCCs; p < 0.001). Quantitative analysis showed no significant difference between rise time and time to peak. Tumor-to-cortex (TOC) enhancement ratio in AMLs was significantly lower than that in ccRCCs (p < 0.001). The criteria of centripetal enhancement and homogeneous peak enhancement together with TOC ratio < 91.0% used to differentiate hypoechoic AMLs from ccRCCs resulted in a sensitivity and specificity of 68.9% and 95.8%, respectively. CONCLUSION: Both qualitative and quantitative analysis with CEUS are valuable in the differential diagnosis of hypoechoic renal AMLs from ccRCCs.

ABSTRACT

A 48-year-old male patient with chronic alcoholism presented with a soft, bulky, asymptomatic, and slow-growing mass in the posterior region of the neck, as well as nodules in the deltoid region and posterior triangle of the sternocleidomastoid muscle. Needle aspiration confirmed the diagnosis of lipoma. Multiple symmetric lipomatosis (Madelung's disease) is a rare proliferation of adipocytes, of unknown etiology, most common in middle-aged men and mainly associated with alcoholism. It predominantly affects the neck and upper trunk, causing compressive symptoms or a imparting a pseudoathletic appearance. Surgical resection or liposuction is the most effective treatment, despite frequent recurrence.

ABSTRACT

Retropharyngeal lipoma is a rare benign tumor [less than 27 reports in literature] of nonspecific clinical symptoms. It can grow to an enormous extent causing total obstruction of the upper respiratory tract. Until now its etiology is unknown. A 60-year old female complained from severe snoring, mild dysphagia and moderate respiratory difficulty with gradual onset since one year prior to clinical presentation. In Oropharyngeal examination and indirect laryngoscopy, there was a bulging over posterior pharyngeal wall extending from the level of soft palate to lower part of hypopharynx with moderate closure of laryngeal inlet and soft consistency on palpation. Fine needle aspiration was in favour of neurofibroma but CT scan and MRI showed criteria of a large retropharyngeal lipoma [75x50 mm,oval shaped]. The mass was removed completely via transpharyngeal approach with creation of U- shaped flap. Post operative pathologic study confirmed the diagnosis of lipoma. Lipoma as differential diagnosis of retropharyngeal tumors always has to be considered. Surgical intervention through pharyngeal or cervical root is recommended. To prevent functional complications resulting from tumor and surgery and to get information about the extent of the lipoma, accurate radiological imaging is mandatory

ABSTRACT

CT and MRI are utilized to differentiate between different types of masses and to determine the extent of lesions involving the lacrimal gland and the fossa. Although many diseases that affect the lacrimal gland and fossa are specifically diagnosed by imaging, it is frequently very difficult to differentiate each specific disease on the basis of image characteristics alone due to intrinsic similarities. In lacrimal gland epithelial tumors, benign pleomorphic adenomas are seen most commonly with a well defined benign appearance, and a malignant adenoid cystic carcinoma is seen with a typical invasive malignant appearance. However, a malignant myoepithelial carcinoma is seen with a benign looking appearance. Lymphomatous lesions of the lacrimal gland include a broad spectrum ranging from reactive hyperplasia to malignant lymphoma. These lesions can be very difficult to differentiate both radiologically and pathologically. Generally, lymphomas tend to occur in older patients. The developmental cystic lesions found in the lacrimal fossa such as dermoid and epidermoid cysts can be diagnosed when the cyst involves the superior temporal quadrant of the orbit and manifests as a non-enhancing cystic mass and, in case of a lipoma, it is diagnosed as a total fatty mass. However, masses of granulocytic sarcoma and xanthogranuloma, as well as vascular masses, such as a hemangiopericytoma, are difficult to diagnose correctly on the basis of preoperative imaging findings alone. A careful clinical evaluation and moreover, a pathologic verification, are needed. In this pictorial review, the various imaging spectrums of pathologic masses involving the lacrimal gland and fossa are presented, along with appropriate anatomy and pathology reviews.
