Abstract We present CT scan, MRI and histopathologic findings of two patients harboring a rare type of meningioma. In the first case, a 52 year-old male patient, a large parasellar mass invading the cavernous sinus, infiltrating the infratemporal fossa and extending as low as C2 was founded. The tumor was isointense on T1, enhanced strongly with gadolinium injection, and was hyperintense on T2. In the second case, a 19-year-old male patient, a large high density temporal right mass was disclosed by CT scan. Both patients were taken to surgery. In the first case, only a partial removal was possible to be accomplished due to a severe intra operative bleeding. In the second case, the tumor was totally removed. Both showed characteristic pathologic findings of a meningioma resembling a chordoma. Meningioma is a relatively common intracranial tumor, occurring most frequently in adults, showing a wide variety of growth patterns. We described a pattern that had a peculiar chordoma-like appearance. The pathological findings and the differential diagnosis from chordoma are discussed.

Relatamos os achados tomográficos, de ressonância magnética e histopatológicos de dois pacientes com um tipo raro de meningioma. O primeiro era um paciente de 52 anos, do sexo masculino, portador de massa para selar volumosa, invadindo o seio cavernoso, infiltrando a fossa infratemporal e se estendendo ao nível de C2. O processo expansivo era isodenso em T1, contrastando-se intensamente com a injeção de gadolíneo e espontaneamente hiperintenso em T2. O segundo era um paciente de 19 anos, do sexo masculino, com grande massa, espontaneamente hiperdensa, em região temporal esquerda, na tomografia computadorizada de cranio. Ambos foram tratados cirurgicamente. No primeiro, somente a ressecção parcial foi possível devido a presença de intenso sangramento intra-operatório. No segundo o tumor foi totalmente removido. Ambos apresentavam características patológicas sugestivas de meningioma cordóideo. O meningioma intracraniano é relativamente comum, ocorre em adultos, apresentando diversos tipos histológicos. O meningioma cordóideo representa forma rara deste tipo de tumor, devendo ser diferenciado dos cordomas.
