MRI of the posterior fossa of a young adult demonstrates a cystic mass in the superior aspect of the left cerebellar hemisphere. An excentric solid component is seen anterolaterally which is somewhat hypointense on T1 and hyperintense on T2 compared to adjacent brain. A minor degree of high T2 signal is seen surrounding the mass consistent with oedema.
Following administration of contrast the solid component enhances vividly , with no evidence of enhancement of the cyst wall. Features are consistent with a haemangioblastoma of cerebellum. (confirmed histologically)
No other lesions are identified to suggest underlying von Hippel Lindau syndrome.
