A 25-yr-old male presented with a cerebellar mass, underwent a suboccipital craniotomy, and was diagnosed with medulloblastoma. Six months later he developed a large mass in the right iliac crest. Fine-needle aspiration biopsy (FNAB) confirmed the diagnosis of metastatic medulloblastoma. The diagnosis of metastatic medulloblastoma is usually suspected clinically or radiographically, and is uncommonly confirmed by cytologic evaluation. Here we report on a rare case of FNAB used to diagnose metastatic medulloblastoma.
