RESUMO
Five patients with supratentorial dermoid cysts who were surgically treated are presented. There were three males and two females, between the ages of 17 and 35 years (mean 26.6 years). The tumor location was frontobasal and/or temporobasal. The duration of illness before the diagnosis ranged from 1 to 14 months (mean 7.4 months). Clinical presentation included seizures, intracranial hypertension syndrome, aseptic meningitis, homonimous lateral hemianopsia, and memory defect. Preoperatively, all patients were investigated by computerized tomography (CT); in two cases, magnetic resonance (MR) imaging was also obtained. Tumor removal was performed by microsurgical procedures; it was total in 3 cases and subtotal in the remaining 2 cases. Histologically, all of the tumors exhibited the typical dermoid cyst pattern. There were no operative deaths. Two patients experienced postoperative language dysfunction and/or hemiparesis. No patient developed clinicoradiological evidence of tumor recurrence at 1 to 10 years (mean 5 years) following surgery. These results are discussed in light of the data previously reported by the literature.

The authors report a rare case of epidermoid cyst with interhemispheric growth closely connected to the anterior portion of the corpus callosum. Although extremely sensitive in determining the site, dimensions and relations of the lesion, NMR does not allow the nature of this pathology to be diagnosed owing to the lack of signal specificity. CT, using the measurement of Hounsfield units, allows a differential diagnosis of epidermoid cysts and arachnoid cysts and lipomas to be made in almost all cases. Treatment is surgical and the complete excision of the capsule avoids recidivation.

The authors analyse the incidence, extent and prognostic significance of lymphocytic infiltration in 80 cases of operated cerebral gliomas (61 high- and 19 low-grade gliomas). The results obtained are discussed in relation to the data previously reported by the literature.
