- Usually benign, vascular, and slow-growing adult cerebellar tumor
- WHO grade I
- Well-circumscribed, highly vascular mass composed of stromal cells and small blood vessels
- Sporadic or familial
- Familial cases associated with von Hippel-Lindau (VHL) disease
- Up to 40% of all hemangioblastomas (HGBLs) are in patients with VHL disease
- Often multiple, including retinal HGBLs
- Sporadic and VHL disease cases both demonstrate erythropoietin upregulation
- Sporadic: most commonly afflicts people aged 40 to 60 years
- VHL disease: afflicts younger people
- Slight male gender predilection
- Common presenting signs/symptoms related to increased intracranial pressure due to posterior fossa obstructive hydrocephalus
- Vomiting, altered mental status, macrocephaly
- Treatment: surgical resection
- Favorable prognosis: 10-year survival, 85%
- Tumor recurrence in up to 20%
- Leptomeningeal dissemination rare
- Posterior fossa mass
- Supratentorial, retinal HGBLs in patients with VHL disease
- Cyst with enhancing mural nodule common morphology but sometimes solid without cyst
- May have surrounding edema, particularly in the setting of hemorrhage
- Posterior fossa mass
- Hypodense cyst
- Isodense to hyperdense solid nodule
- Rare hyperdense hemorrhage, often with surrounding hypodense cerebellar edema
- Solid nodular component will enhance on contrast-enhanced CT
- T1WI: isointense nodule, ±flow voids
- T2WI: hyperintense cyst and nodule, possible surrounding hyperintense edema
- FLAIR: hyperintense cyst and nodule, possible surrounding hyperintense edema
- T2*GRE: hypointense signal if hemorrhage is present
- T1WI+C: avidly enhancing nodule; nonenhancing cyst, usually without cyst wall enhancement
- DWI: possible DWI-bright, ADC-dark diffusion restriction in cystic component
- MRS: elevated Cho, decreased NAA, ±lactate/lipid peaks
- MRI without and with intravenous contrast; screen patients with VHL disease, including both brain and spine, beginning in early childhood
