ABSTRACT

El condrosarcoma ocupa el tercer puesto dentro de las neoplasias óseas primarias, siendo la columna vertebral una localización inusual. Según su etiología se clasifican en condrosarcoma primario o secundario a lesiones subyacentes de tipo cartilaginosa como el encondroma u osteocondroma; siendo entre el 80-90% de bajo grado. Pueden presentarse en cualquier nivel de la columna vertebral, siendo más frecuente en la región torácica y cervical, comprometiendo los elementos posteriores de la vértebra, los cuerpos vertebrales o ambos, en un 40%, 15% y 45% respectivamente. El síntoma más común es el dolor localizado asociado a manifestaciones neurológicas. El método diagnóstico de elección es la biopsia por punción y el tratamiento se basa fundamentalmente en la resección quirúrgica


Chondrosarcoma occupies the third position within the primary bony neoplasia's, with an unusual location at the level of the spine. According to their etiology, they are classified as primary chondrosarcoma or secondary to underlying cartilaginous lesions such as the enchondroma or osteochondroma, being between 80-90% of low grade. They can occur at any level of the spine, being more frequent in the thoracic and cervical region, compromising the posterior elements of the vertebra, the vertebral body or both, by 40%, 15% and 45% respectively. The most common symptom is localized pain associated with neurological manifestations. The diagnostic method of choice is biopsy and treatment is based primarily on surgical resection.

ABSTRACT

OBJECTIVE@#To develop and validate radiomics models based on non-enhanced magnetic resonance (MR) imaging for differentiating chondrosarcoma from enchondroma.@*METHODS@#We retrospectively evaluated a total of 68 patients (including 27 with chondrosarcoma and 41 with enchondroma), who were randomly divided into training group (=46) and validation group (=22). Radiomics features were extracted from TWI and TWI-FS sequences of the whole tumor by two radiologists independently and selected by Low Variance, Univariate feature selection, and least absolute shrinkage and selection operator (LASSO). Radiomics models were constructed by multivariate logistic regression analysis based on the features from TWI and TWI-FS sequences. The receiver-operating characteristics (ROC) curve and intraclass correlation coefficient (ICC) analyses of the radiomics models and conventional MR imaging were performed to determine their diagnostic accuracy.@*RESULTS@#The ICC value for interreader agreement of the radiomics features ranged from 0.779 to 0.923, which indicated good agreement. Ten and 11 features were selected from the TWI and TWI-FS sequences to construct radiomics models, respectively. The areas under the curve (AUCs) of TWI and TWI-FS models were 0.990 and 0.925 in training group and 0.915 and 0.855 in the validation group, respectively, showing no significant differences between the two sequence-based models (>0.05). In all the cases, the AUCs of the two radiomics models based on TWI and TWI-FS sequences and conventional MR imaging were 0.955, 0.901 and 0.569, respectively, demonstrating a significantly higher diagnostic accuracy of the two sequence-based radiomics models than conventional MR imaging (<0.01).@*CONCLUSIONS@#The radiomics models based on TWI and TWI-FS non-enhanced MR imaging can be used for the differentiation of chondrosarcoma from enchondroma.

ABSTRACT

Abstract Objective Enchondromas are the commonest tumors of the bones of the hand. Treatment approaches vary. The present article presents the characteristics of the tumors, diagnostic methods, and treatments. Methods We discuss the approach used in our institution, where we have treated 48 patients with enchondromas of the hand between 1996 and 2016. Our technique of treatment, which has remained the same over 2 decades, comprises the use of curettage, high-speed burr, and autologous bone graft (harvested with a minimally invasive technique, using a Craig biopsy needle). Results Pain and fractures were the most common symptoms leading the patients to consultation, at frequencies of 33.3% and 31.3%, respectively. A total of 27.1% of the cases were asymptomatic, and their lesions were discovered incidentally. The mean age was 34.4 years (SD = 12.9 years). Tumors were more frequently presented in the ulnar side of the hand, in the fifth ray (41.5%) and in the proximal bones (in the proximal phalanges [43.8%], and in the metacarpal [33.3%]). The size of the tumors ranged from 0.2 cm2 to 5.7 cm2, with a mean of 1.7 cm2 (standard deviation [SD] = 1.0 cm2) and were not associated with fracture (p = 0.291). Fracture was also not associated with any of the symptoms, neither with the age of the patients (p = 0.964). After the treatment, most patients achieved full range of motion (91.7%), with good integration of the bone graft. Three patients presented deficit in range of motion (6.3%) and the incidence of complications was also 6.3% (3 patients). At the end, after the needed surgical revisions, these three patients also recovered full function. They achieved full bone graft integration, regained full range of motion and returned to work. There was no tumor recurrence case during the follow-up period evaluated. For all cases, no donor site complications occurred. Conclusion Our method of treatment has consistently provided good outcomes, with only a few minor complications. Therapeutic level of evidence: IV.


Resumo Objetivo Os encondromas são os tumores mais comuns dos ossos da mão, com uma grande variedade de abordagens terapêuticas. O presente artigo apresenta as características dos tumores, métodos diagnósticos e tratamentos. Métodos Discutimos a abordagem da nossa instituição, onde tratamos 48 pacientes com encondromas da mão, entre 1996 e 2016. Nossa técnica de tratamento, que permanece a mesma ao longo de duas décadas, compreende o uso de curetagem, esmeril de velocidade e enxerto ósseo autólogo (retirado com uma técnica minimamente invasiva, usando uma agulha de Craig). Resultados A dor e as fraturas foram os sintomas mais comuns, levando os pacientes à consulta, nas frequências de 33,3% e 31,3%, respectivamente. Um total de 27,1% dos casos era assintomático, e suas lesões foram descobertas incidentalmente. A média de idade foi de 34,4 anos (desvio padrão [DP] = 12,9 anos). Os tumores foram mais frequentemente encontrados no lado ulnar da mão, no quinto raio (41,5%), e nos ossos proximais (nas falanges proximais [43,8%] e no metacarpo [33,3%]). O tamanho do tumor variou de 0,2 cm2 a 5,7 cm2, com média de 1,7 cm2 (DP = 1,0 cm2) e não foi associado à fratura (p = 0,291). A fratura também não foi associada a nenhum dos sintomas, e nem à idade dos pacientes (p = 0,964). Após o tratamento, a maioria dos pacientes alcançou amplitude completa de movimento (91,7%), com boa integração do enxerto ósseo. Três pacientes apresentaram déficit no arco de movimento (6,3%) e a incidência de complicações também foi de 6,3% (3 pacientes). No final, após as revisões cirúrgicas necessárias, esses três pacientes também recuperaram a função completa. Eles tiveram a integração total do enxerto ósseo, recuperaram toda a amplitude de movimento e retornaram ao trabalho. Não houve nenhum caso de recorrência do tumor durante o período de acompanhamento avaliado. Em nenhum dos casos ocorreram complicações no local doador. Conclusão O nosso método de tratamento forneceu consistentemente bons resultados, com apenas algumas complicações menores. Nível terapêutico de evidência: IV.

ABSTRACT

This case report describes the unusual occurrence of a flexor digitorum profundus avulsion secondary to an enchondroma of the distal phalanx of the middle finger. The enchondroma was treated by simple curettage with an autogenous bone graft harvested from the olecranon. The avulsed bone fragment was reattached to the distal phalanx using the pull-out suture technique. Bony union and full function of the digit were achieved.

ABSTRACT

INTRODUCCIÓN: Los tumores óseos primarios son raros. La localización, extensión y el carácter lítico dificultan el tratamiento aunque el comportamiento biológico sea benigno. OBJETIVO: Valorar las características y tratamientos de los tumores óseos benignos primarios líticos activos o agresivos tratados en el Hospital El Cruce. Comparar la resección realizada con la sugerida por los criterios de Enneking. MATERIAL Y MÉTODOS: se evaluaron historias clínicas y ateneos postquirúrgicos de pacientes con diagnóstico de tumores músculoesqueléticos atendidos en el Servicio de Ortopedia y Traumatología del Hospital El Cruce desde agosto de 2008 hasta junio de 2017. Se utilizaron los criterios de Ennekingde comportamiento biológico y resección. RESULTADOS: Se evaluaron 26 pacientes con diagnóstico de tumor benigno lítico activo o agresivo sobre un total de 124 tumores musculoesqueléticos primarios operados. Un paciente se reclasificó como maligno en la resección completa, por lo que se consideraron 25. Se trató de 16 mujeres, 9 varones, edad media 28,4.La localización fue: 13 miembro inferior (1coxal, 7 fémur, 3 tibia y 2 calcáneo), 9 miembro superior (1 húmero, 2 radio, 2 cúbito, 3 metacarpianos y 2 falanges) y 3 columna (1 cervical, 1 torácica y 1 sacra). Un paciente tuvo localización múltiple en la mano. Según Enneking 10 eran activos y 13 agresivos. Histología: 12 Tumores de células gigantes (TCG), 5 condromas, 4 quiste óseo simple, 3 quiste óseos aneurismáticos y 1 hemangioma. La resección fue intralesional en 16, en 3 marginal y en 6 amplia (1 amputación). La media de días de estada fue 7 días (0 a 33), 5 internación en UTI. La reconstrucción se hizo con: Injerto de Banco 7, Injerto de cresta 7, Injerto M.sup 3, Prótesis 2, Peroné vascularizado 2, Sustituto óseo y cemento en 1. Sin reconstrucción en 2. Dos tuvieron adyuvancia con denosumab. Once tuvieron complicaciones. Hubo un óbito. En 18/25 la resección realizada coincidió con los criterios de resección (Enneking). CONCLUSIONES: A pesar de la benignidad histológica, los tumores líticos primarios requirieron procedimientos complejos, con un 40 % de complicaciones. En el 72% la resección realizada concordó con los criterios de resección de Enneking.


INTRODUCTION: Primary bone tumors are rare. The localization, extension and lytic character make the treatment difficult even though the biological behavior is benign. OBJECTIVES: Assess the characteristics and treatments of active or aggressive benign primary lytic bone tumors treated in the El Cruce hospital. Compare the resection made with the one suggested by Enneking criteria. MATERIALS AND METHODS: Clinical records and postsurgical grand rounds were evaluated on patients diagnosed with musculoskeletical tumors treated in the Orthopedics and Traumatology Service of Hospital El Crucefrom August 2008 to June 2017. Enneking's criteria based on biologic behavior and resection were used. RESULTS:Twenty-six patients diagnosed with active or aggressive lytic bone tumor were evaluated out of a total of 124 operated primary musculoskeletal tumors. A patient was reclassified as malignant on the complete resection, therefore 25 were considered. There were 16 women, 9 men; average age was 28.4.The tumor localization was: 13 in lower extremity (1 coxal, 7 femoral, 3 tibial and 2 in calcaneus), 9 in upper extremity (1 humeral, 2 radial, 2 ulnar, 3 metacarpal y 2 in phalanges) and 3 in spine (1 cervical, 1 thoracic y 1 sacral). A patient had multiple localizations in his hand. Based on Enneking, 10 were active and 13 were aggressive. Histology: 12 giant-cell tumors (GCT), 5 chondromas, 4 simple bone cysts, 3 aneurysmal bone cysts and 1 hemangioma. The resection was intralesional in 16, marginal in 3 and ample in 6 (1 amputation). Mean hospitalization stay was 7 days (0 to 33), 5 days in ICU. The reconstruction was made with: draft from banks in 7, drafts from crests in 7, draft from upper extremity in 3, prosthesis in 2, vascularized fibula in 2, bone substitute and cement in 1. No reconstruction in 2.Two had adjuvant therapy with denosumab. Eleven had complications. There was one death. In 18 out of 25, the resection matched the resection criteria (Enneking). CONCLUSIONS: Despite the histological benignity, primary lytic tumors required complex procedures and there were 40% complications. In72%, the resection matched the resection criteria (Enneking).

ABSTRACT

Introducción. El condroma es una neoplasia benigna de origen mesenquimal y de etiología desconocida, muy infrecuente en los tejidos blandos debido a su constitución de células de cartílago maduro sin hueso; sin embargo, son frecuentes las calcificaciones focales. Al presentarse en cabeza y cuello, suele hacerlo en el maxilar o el paladar duro, y son pocos los reportes de este tumor en el espacio parafaríngeo. Se reporta el caso de una paciente de 68 años de edad, que acudió a consulta por dolor en el paladar blando, cefalea y dolor paratiroideo izquierdo asociado a disfagia de cuatro años de evolución. Se practicaron los estudios pertinentes y, finalmente, se confirmó el diagnóstico de condroma mediante biopsia. Discusión. Los condromas muy rara vez se encuentran en los tejidos blandos, por lo cual se sugiere que el diagnóstico sea cuidadosamente orientado para descartar una posible malignidad de la lesión y que los controles posquirúrgicos sean frecuentes


Introduction: Chondroma is a benign neoplasm of mesenchymal origin and of unknown etiology, very infrequently appearing in the soft tissues due to its constitution of mature cartilage cells without bone; however, they usually present focal calcifications. When occurring in the head and neck, they usually appear in the jaw or hard palate. Just a few cases of this pathology are reported in the pharynx. Materials and Methods: We present a case of a female 68 years old, who came to the clinic due to pain in the soft palate, headache and left parathyroid pain associated with dysphagia, of four years of evolution. Corresponding studies were carried out and finally the diagnosis of chondroma was confirmed by biopsy. Discusion: Chondromas are rarely found in the soft tissues, suggesting that the diagnosis should be carefully oriented to rule out possible malignancy of the lesion and that post-surgical controls should be frequent

ABSTRACT

Prompted by a unique case of an ectomesenchymal chondromyxoid tumor (ECT) of the palate in a 54-year-old female, we reviewed the English and German literature on this entity until the end of 2016 using PubMed. The search produced 74 lingual cases with a nearly equal sex distribution and a mean age of 39.3 years, and two extra-lingual cases sharing histological and immunohistological features including nodular growth, round, fusiform or spindle-shaped cellular architecture, and chondromyxoid stroma. Immunophenotyping showed the majority of cases to be positive for glial fibrillary acidic protein (GFAP), S-100 protein, glycoprotein CD57, pancytokeratin (AE1/AE3), and smooth muscle actin (SMA); in isolated cases there was molecular-genetic rearrangement or gain of Ewing sarcoma breakpoint region 1 (EWSR1) but no rearrangement of pleomorphic adenoma gene 1 (PLAG1). At present, ectomesenchymal cells that migrate from the neural crest are considered to play a pivotal role in tumor origin. All cases had a benign course, although there were three recurrences. Because of the rarity of this tumor and the need for differential diagnostic differentiation from myoepithelioma and pleomorphic adenoma, both oral surgeons and pathologists should be aware of this entity.

ABSTRACT

PURPOSE: To report a case of orbital chondroma. CASE SUMMARY: A 15-year-old male presented with an 8-month history of left hypertropia. The best-corrected visual acuity was 20/20 in both eyes. The exophthalmometry showed no exophthalmos, with 13 mm in both eyes. There was a hard palpable mass at the superonasal orbit of the left eye. Orbital computed tomography showed a heterogenous soft tissue shadow at the superonasal orbit of the left eye, and orbital magnetic resonance imaging revealed a 25 × 16 × 20 mm well-defined mass with low signal intensity in the T1-weighted image, high signal intensity in the T2-weighted image, and heterogenous enhancement in the contrast enhanced T1-weighted image. The mass was surgically removed with anterior orbitotomy. A 27 × 17 mm well-capsulated lobular mass was found, and histopathological examination revealed hyaline cartilage and chondrocyte. The mass was diagnosed as a chondroma. CONCLUSIONS: A chondroma is a benign tumor, which usually occurs in long bones and the small bones of the hands and feet. It is very rare in the facial and pelvic bones. The sites of chondroma occurring in the head and neck include the ethmoid sinus and maxilla, but it is extremely rare in the orbit.

ABSTRACT

Carney described a disorder characterized by the presence of several uncommon tumors which were pulmonary chondromas, gastric sarcomas and extra-adrenal paragangliomas. We report a 14 year-old girl in whom multiple gastric tumors were discovered during a study of an iron deficiency anemia and was subjected to a partial gastrectomy. At 25 years of age, she developed several pulmonary chondromas and at 33 years, a mediastinal tumor with features of an extra-adrenal paraganglioma was found. At 35 years of age, a total gastrectomy was performed to remove a gastrointestinal stromal tumor with excision of peritoneal and lymph node metastasis. One year later, the patient died due to liver failure secondary to liver metastases.

ABSTRACT

Los tumores condroides de la laringe son poco frecuentes, y generalmente se ubican en el cartílago cricoides. El tratamiento de elección es quirúrgico, con buen pronóstico general. Se presenta el caso de un hombre de 60 años con historia de disfonía. El estudio nasofaringolaringofibroscópico revela una masa laríngea supraglótica. Las imágenes son compatibles con una lesión del cartílago tiroides. La biopsia obtenida por microlaringoscopía directa informa tumor compatible con condroma. Se realiza una resección completa de la masa por abordaje externo, la biopsia corrobora el diagnóstico de tumor condroide de bajo grado. Se describe esta patología mediante revisión bibliográfica.


Chondroid tumors of the larynx are uncommon, and usually located in the cricoid cartilage. Surgery is the treatment of choice, with good prognosis in general. We report the case of a 60-year-old man consulting for dysphonia. The nasopharyngolaryngoscopy showed a supraglottic laryngeal mass. The images were compatible with a thyroid cartilage lesion. The biopsy sample obtained by direct microlaryngoscopy was consistent with a condroma. A complete excision of the lesion was performed by external approach and the biopsy confirmed the diagnosis of a low grade chondroid tumor. We present a review of chondroid tumors of the larynx based on available literature.

ABSTRACT

Introducción: los encondromas solitarios son los tumores óseos más comunes de la mano. Aproximadamente el 40% compromete esta extremidad, con predilección por los rayos cubitales y las falanges proximales. El riesgo de transformación maligna a condrosarcoma es del 1% y el de recurrencia, del 2-15%. Se describen la experiencia y los resultados de un importante número de pacientes con un seguimiento a largo plazo. Materiales y Métodos: Estudio descriptivo, retrospectivo, de tipo serie de casos. Se seleccionaron pacientes con diagnóstico confirmado de encondroma solitario de la mano, que fueron manejados mediante resección con curetaje del tumor más aplicación de injertos autólogos de cresta ilíaca o radio. Después del tratamiento quirúrgico, se evaluaron la función, mediante la clasificación de Takigawa, los resultados radiográficos y la frecuencia de complicaciones o recidivas. Resultados: Se incluyeron 19 pacientes con un seguimiento posoperatorio promedio de 11 años. De acuerdo con la clasificación de Takigawa, la función fue excelente en 16 pacientes (84,2%) y buena en 3 (15,7%). Un paciente presentó una infección del sitio operatorio incisional superficial, con resolución completa. No hubo recidivas. Conclusiones: En los pacientes evaluados, los resultados funcionales y radiológicos fueron buenos después de la cirugía. Los encondromas plantean el riesgo de fracturas patológicas, recidiva y, en menor proporción, de transformación maligna; sin embargo, esto no ocurrió en ninguno de los casos. Se describe una opción de manejo quirúrgico, sencilla con buenos y excelentes resultados a largo plazo.


Introduction: Isolated enchondromas are the most common tumors of the hand. Approximately 40% affect this upper extremity, with preference for cubital rays and proximal phalanges. Risk of malignant transformation to chondrosarcoma is 1% and the risk of recurrence ranges from 2 to 15%. Our experience and results with a large number of patients with a long-term follow-up are described. Methods: Descriptive, retrospective, case series study. Patients with diagnosis of isolated enchondroma of the hand that were treated with tumor resection, curettage and iliac crest or radius autograft placement were included. After surgical treatment, hand function was assessed using the Takigawa classification, radiological results and frequency of complications or recurrence were evaluated. Results: Nineteen patients with a mean follow-up of 11 years were included. According to the Takigawa classification, function was excellent in 16 patients (84.2%) and good in 3 (15.7%). One patient had an incisional superficial surgical site infection that resolved completely. No cases of recurrence were identified. Conclusions: Good functional and radiological results were obtained after surgical treatment. Enchondromas can pose the risk of pathological fractures, recurrence and, in a lesser degree, malignant transformation; however, none of these complications were identified. The results of a simple surgical treatment option with good and excellent long-term results are described.

ABSTRACT

Enchondromas generally occur in the hand and uncommonly in the long bones. Because enchondromas are usually asymptomatic, most are discovered during diagnostic radiology for another disease. Here, we describe a case of enchondroma in the right humerus in a 79-year-old female patient with concomitant rotator cuff tear arthropathy. The patient was initially hospitalized for prolonged pain and pseudoparalysis of the right shoulder. The condition, which was histologically confirmed as an enchondroma in the proximal humerus, was treated with curettage and reverse total shoulder arthroplasty. In this case report, we present a rare case of an enchondroma with combined rotator cuff tear arthropathy.

ABSTRACT

PURPOSE: We analyzed outcomes after management of enchondroma involving short tubular bones of the hand and foot by curettage and grafting using allogenic bone or bone substitutes. MATERIALS AND METHODS: Twenty-two patients (allogenic bone 15 and bone substitutes 7 patients) were recruited. Clinical results were assessed by pain, cosmetic problem, range of motion of joint and the power of grasp. Radiographic outcomes were analyzed by degree of bone defect. RESULTS: Clinically, 19 patients were classified as excellent and 3 patients as good. Three patients with K-wire fixation had pain with local irritation, which was easily controlled by removal of the K-wires. There were no complications including deep infection, delayed or nonunion, refracture. Radiographically, 20 cases were classified as group 1 (bone defect smaller than 3 mm) and the 2 remaining cases were classified as group 2 (bone defect 4-10 mm). CONCLUSION: Curettage and graft using allogenic bone or bone substitute is an effective modality of treatment for enchondroma involving short tubular bones of the hand and foot. When combined with pathologic fracture, early surgical management could shorten duration of immobilization. Surgical management might be considered for the lesion involving the foot when discovered because of high incidence of pathologic fracture.

ABSTRACT

El síndrome de Carney es una enfermedad rara, con diferentes formas de presentación, que afecta principalmente al sexo femenino y es asintomática en la mayoría de los casos. Se caracteriza por la aparición de tumores, generalmente benignos, principalmente en el pulmón, la glándula suprarrenal y el estómago; sin embargo, se pueden afectar otros órganos como el esófago. Su tratamiento es principalmente quirúrgico. Se presenta el caso de una paciente con síndrome incompleto de Carney, manejada quirúrgicamente, con excelente resultado posoperatorio. Se hace una revisión de la literatura científica actual.


Carney's triad is a rare condition with multimodal presentations, which affects mainly females and remains asymptomatic in most cases. It is characterized by the appearance of tumors, usually benign, in lung, adrenal, and stomach, but it can also affect other organs like the esophagus. Treatment of these lesions is primarily surgical. The objective of this paper is to review the current literature and to report a case of an incomplete Carney's triad managed surgically with excellent postoperative results.

ABSTRACT

Introduction: Cartilage is an uncommon component in breast lesions, most of cases it correspond to metaplasia of malignant neoplasm and its occurrence in benign tumors is exceptional. Cartilage- containing breast benign tumors has been subclassified by their majors features accord to each author, but their main composition remains to be adipose tissue, fibrous stroma and cartilage, with or without breast epithelium. Chondrolipoma of the breast was reported for the first time by Kaplan in 1977, and since then reports of this entity has been anecdotal with less than 20 cases published. Clinical case: We expose the first case diagnosed of chondrolipoma of the breast in Colombia, performed on the Pathology Department of Universidad Industrial de Santander (Bucaramanga-Colombia) along with a literature review, due to the low frequency of this diagnosis and the few information about it.


Introducción: El cartílago es un componente poco común en las lesiones de mama, la mayoría de casos corresponden a metaplasias de lesiones malignas siendo excepcional el hallazgo en lesiones benignas; estas últimas se han subclasificado de acuerdo a las características histológicas destacables para cada autor, pero globalmente se componen de tejido adiposo, estroma fibroso y cartílago, mientras que el componente epitelial mamario es de presentación variable. El condrolipoma de mama fue reportado por primera vez en 1977 por Kaplan y desde esa fecha los reportes han sido anecdóticos con menos de 20 casos publicados. Caso clínico: Se expone el primer caso diagnosticado en Colombia de condrolipoma de mama, diagnóstico efectuado en el Departamento de Patología de la Universidad Industrial de Santander (Bucaramanga-Colombia) y se hace una revisión de la literatura de esta entidad, dada la baja frecuencia de su diagnóstico y a la escasa información al respecto.

ABSTRACT

Chondromas are a benign cartilaginous tumor that account for approximately 0.5% of primary intracranial tumors. They usually arise from the synchondrosis of the skull base, being rarely reported elsewhere (dura convexity, falx, or even intraparenchymal). Because they are very rare tumors sharing clinical behavior and imagiological similarities with the much more common meningioma, the clinical diagnosis is frequently mistaken after an initial imaging workup. The authors present a case of a 48-year-old woman, with frequent headaches and an extra-axial tumor arising from the anterior falx, initially diagnosed as a meningioma.


Condromas são tumores cartilaginosos benignos que correspondem por aproximadamente 0,5% dos tumores primários intracranianos. Eles geralmente surgem da sincondrose da base do crânio, sendo raramente registrados em outros locais como a convexidade dural, a foice, até mesmo no parênquima cerebral. Por serem tumores muito raros que compartilham comportamento clínico e imagiológico com meningiomas, o diagnóstico é frequentemente confundido após exame de imagem inicial. Os autores apresentam o caso de uma mulher de 48 anos, com cefaleia frequente e um tumor extra-axial ascendendo da foice anterior, inicialmente diagnosticado como um meningioma.
