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

Abstract Background Henoch-Schonlein 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. Case description 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. Conclusions Intracerebral hemorrhages during HSS share a favorable prognosis and a posterior lobar localization, typically involving the parieto-occipital region. The case described here is unusual because the patient did not have the typical purpuric rash and unlike published cases, the intracranial hemorrhage marked the onset of HSS rather than complicating a typical HSS presentation .
