@entity1 @entity66 @entity424 @entity5 @entity7241 @entity909
Ependymomas usually arise from the ventricular surface and approximately two-thirds of them are infratentorial. We present an unusual case of @entity424 located in the parietal parenchyma and exhibiting no continuity with the ventricular system. On March 30, 1998, a 63-year-old @entity1 was admitted to our neurosurgical service because of a @entity909 attack two weeks before. On admission, neurological examination revealed no abnormal findings. Computerized tomography (CT) revealed a @entity66 of the parietal lobe which was enhanced homogeneously. Magnetic resonance imaging (MRI) also showed the mass of the parietal lobe which was iso-intense on T1-weighted images, iso and high intense on T2-weighted images and homogeneously enhanced by administration of @entity7241 . In the angiography, left carotid angiograms showed a @entity5 stain. On February 26, 1998, total @entity5 was performed using stereotactic craniotomy with neuronavigator and intraoperative echography. After surgery, focal radiation therapy (56Gy) was carried out. The pathological diagnosis was @entity424 with partial clear cell components. Several kinds of @entity5 may occur in the cerebral parenchyma. We conclude, however, that @entity424 has to be included in the differential diagnosis when the @entity5 location is distant from the ventricles.
