====== Posterior Fossa Hemangioblastoma ====== S/S of cerebellar HGB are usually those of any p-fossa mass—H/A, N/V, cerebellar findings...; see [[Posterior fossa tumor]]s — and [[obstructive hydrocephalus]] may occur. HGB is rarely documented as a cause of [[apoplexy]] due to [[intracerebral hemorrhage]] (ICH) (lobar or cerebellar); however, some studies indicate that if cases of ICH are carefully examined, abnormal vessels consistent with HGB (and occasionally misidentified as AVM) may be found with surprising frequency (in spite of negative CT and/or angiography). see [[Brainstem Hemangioblastoma]] see [[Cerebellar hemangioblastoma]]. see [[Cerebellopontine hemangioblastoma]]
