Medulloblastoma in adults.
Seventeen adult patients (16 years of age and over) with medulloblastoma were managed at King Faisal Specialist Hospital and Research Centre between 1981 and 1992. Nine patients were males and eight were females. The average age at diagnosis was 26.7 years; the females were younger than the males. The average duration of history before diagnosis was 14.5 weeks, the females presenting earlier than the males. The tumors were located in the midline (9) and the hemispheres (8). Nine patients had the desmoplastic variant and eight had standard primitive neuroectodermal tumor. Hydrocephalus developed in 14 of the patients only seven of whom required a shunting procedure. All patients had either subtotal or gross total removal of the tumor. Sixteen patients had postoperative radiation therapy; one patient refused radiation therapy. Two patients had chemotherapy following recurrence of the tumor. The clinical presentation, radiological studies, histological variants, treatment and outcome are discussed in this report.
