Right cerebellar hemangioblastoma

Clinical History:
A 49 year old male with worsening headache, mostly in the posterior neck, and vertigo.

Right cerebellar hemangioblastoma

MR Technique:
Axial pre- and post-contrast T1-weighted scans at the level of the inferior cerebellum are presented, obtained with 2D short TE gradient echo technique at 3 T.

Imaging Findings:
A large intra axial cystic mass is present in the right inferior cerebellum, with an enhancing nodule in its anterior/inferior aspect. The lesion causes mass effect on the medulla, pons, vermis, cerebellum and fourth ventricle. A large feeding artery arising from the right AICA is seen. These findings are most consistent with a hemangioblastoma, with a large feeding vessel. Although much less likely, in particular given the patient’s age, a pilocytic astrocytoma should also be considered in terms of differential diagnosis.
