Hemangioblastoma is a benign, highly vascularized neoplasm of the central nervous system (CNS). This tumor is associated with loss of function of the VHL gene and demonstrates frequent occurrence in von Hippel-Lindau (VHL) disease. While this entity is designated CNS World Health Organization grade 1, due to its predilection for the cerebellum, brainstem, and spinal cord, it is still an important cause of morbidity and mortality in affected patients. Recognition and accurate diagnosis of hemangioblastoma is essential for the practice of surgical neuropathology. Other CNS neoplasms, including several tumors associated with VHL disease, may present as histologic mimics, making diagnosis challenging. We outline key clinical and radiologic features, pathophysiology, treatment modalities, and prognostic information for hemangioblastoma, and provide a thorough review of the gross, microscopic, immunophenotypic, and molecular features used to guide diagnosis.

Abstract PDF: Hemangioblastoma (HB) is a rare benign tumor that most commonly occurs in the cerebellum. HB is composed of neoplastic stromal cells and abundant small vessels. However, the exact origin of stromal cells is controversial. Extraneural HBs have been reported in a small series, and peripheral HBs arising in the adrenal gland are extremely rare. Herein, we report a case of sporadic adrenal HB in a 54-year-old woman. The tumor was a well-circumscribed, yellow mass measuring 4.2 cm in diameter. Histologically, the tumor was composed of small blood vessels and vacuolated stromal cells with clear cytoplasm. On immunohistochemical stain, the stromal cells were positive for S-100 protein, neuron-specific enolase, and synaptophysin. The tumor did not reveal mutation of VHL alleles. We herein present a case of HB of the adrenal gland and review of the literature.

Abstract PDF: Hemangioblastomas comprise 1 to 2% of all intracranial neoplasm, and 8 to 12% of tumors within the posterior fossa. They are composed of admixtures of three different cell types; endothelial cells, pericytes and stromal cells. Although most hemangioblastomas arise sporadically, they are associated with von Hippel-Lindau disease in about 20% cases. We have experienced a case of multiple hemangioblastomas occuiing in the cerebellum, medulla oblongata and cervical spinal cord simultaneously in a 55-year-old male. He had complained of headache, dizziness, generalized weakness and gait disturbance for 2 weeks. The patient had neither specific family history nor increased hematocrit. MRI showed a nonenhancing cystic lesion with an enhancing mural nodule in the right cerebellar hemisphere and two separate enhancing nodules in the medulla oblongata and dorsal cervical spinal cord at the 5-6th. Grossly, the excised mass of the cerebellum, 2.5 x 2 x 1.8cm, was solid to partly cystic, and that of spinal cord, lcm in diameter, was mostly solid. Microscopically, the tumor was composed of thin-walled blood vessels in variable size and interspersed stromal cells. The stromal cells revealed dimorphic cytoplasm that were either homogeneous and eosinophilic, or clear and vacuolated. Immunohistochemically, the endothelial cells reacted positively for glial fibrfllaty acidic protein(GFAP) and vimentin. The stromal cells reacted diffusely positively for vimentin, focally positively for GFAP and S-100 protein near the periphery of the tumor, focally positivel for neuro specipic enolase(NSE), and negatively for lysozyme, desmin and chromogranin. Ultrastructurally, the stromal cells contained numerous microfilaments and lipid droplets.
