Abstract

Supratentorial PNETs are most commonly seen in children and rarely seen in adults. PNET show a proliferation of undifferentiated or poorly differentiated neuroepithelial cells and, thus, are histologically similar to medulloblastomas. They account for approximately 2.5% of brain tumours in children and only 0.4% in adults. Prognosis is poor in the pediatric age group while it shows favourable prognosis in adults. In literature, less than 100 cases of adult PNET have been reported till date with mean age of 35years. PNET in the geriatric age group is rarely been reported
