Henoch-Schönlein syndrome and cerebellar hemorrhage: report of an adolescent case and literature review.

Henoch-Schönlein syndrome (HSS) is a systemic necrotizing vasculitis predominantly affecting children. Symptoms are usually self-limited and only rarely do they involve the central nervous system. Only five published reports describe cases of radiologically proven intracranial hemorrhages complicating HSS. In this 17-year-old boy, a cerebellar hemorrhage developed after aspecific symptoms of upper respiratory tract infection. His past medical history and emerging evidence of systemic bleeding yielded a diagnosis of recurrent HSS. This was the fourth time the disease had recurred since the age of 4. The patient underwent surgical treatment and returned to his normal activities.
