Cerebellar hemangioblastoma associated with primary hyperparathyroidism--case report.

A 57-year-old man presented with a posterior fossa hemangioblastoma associated with primary hyperparathyroidism. The hemangioblastoma was completely removed. Further imaging found parathyroid and thyroid tumors which were resected. Hyperparathyroidism might be a manifestation of von Hippel-Lindau (VHL) disease, but sequencing of the VHL gene of the constitutional deoxyribonucleic acid of the hemangioblastoma was negative. The present association is rare, but the hemangioblastoma and the parathyroid adenoma may have some germ-line mutation in common.
