It can occur sporadically or in association with von Hippel-Lindau (VHL) disease. ===== 🧠 Key Features ===== Location: Most often posterior fossa (especially cerebellum). Histology: Highly vascular with stromal cells, often with foamy cytoplasm. Clinical presentation: Depends on size and location; may include headache, ataxia, visual disturbances, or signs of increased intracranial pressure due to cyst formation or mass effect. Radiology: Cystic lesion with an enhancing mural nodule on contrast MRI is characteristic. Management: Surgical resection is the treatment of choice; stereotactic radiosurgery is an option for select cases. Prognosis: Excellent for sporadic lesions after complete resection; more complex in VHL-associated cases due to multiplicity. ===== Classification ===== see [[Intracranial hemangioblastoma classification]]. ===== Treatment ===== see [[Intracranial hemangioblastoma treatment]].
