Pineal germinoma with massive supratentorial extension. Case report.
An uncommon case of huge pineal germinoma without associated ventricular enlargement is presented. The tumor extended supratentorially in dumb-bell form to affect both cerebral hemispheres, simulating a glioma at neuroradiological examinations. Subtotal removal through a bilateral parieto-occipital approach plus radiation therapy were followed by relief of symptoms for over one year since surgery. The misleading patterns of the tumor and the delayed onset of symptoms in our case are outlined.
