Indium-111 pentetreotide uptake within cerebellar hemangioblastoma in von Hippel-lindau syndrome.

ABSTRACT

A 38-year-old woman with known von Hippel-Lindau syndrome underwent In-111 pentetreotide (OctreoScan) scintigraphy to evaluate a suspected pancreatic neuroendocrine tumor. The patient had undergone surgical resection of a left adrenal pheochromocytoma and a large right cerebellar hemangioblastoma several years previously. Although there was no evidence for recurrence of pheochromocytoma and no uptake within the pancreatic lesion, there was focal tracer accumulation within the left cerebellar hemisphere. MR imaging of the brain confirmed the presence of recurrent hemangioblastoma in the left cerebellum.
