Midline, or intraventricular, oligodendroglioma seems to be very rare; one such case was reported. The patient was a 35-year-old male, admitted in April 1982 with complaints of nausea, headache, and double vision. He had no objective neurological deficit. Plain craniogram and craniotomogram showed abnormal calcification around the 3rd ventricle. CT revealed the calcified mass lesion at the foramen of Monro. A cyst formation was recognized in the anterior horns of the lateral ventricles. Operation was performed through the right frontal transventricular approach and the solid tumor mass and the cyst walls were removed. Pathohistological diagnosis was oligodendroglioma accompanied partially by astrocytoma. Biochemical analysis of the cyst contents revealed similar values of compositions to those of astrocytomas. Adjuvant irradiation therapy of 5, 000 rads was performed. The patient had no neurological deficit and is now working 5 months after the operation.
Characteristics of midline and/or intraventricular oligodendroglioma were described, reviewing the literature.
