Spontaneous intracranial haemorrhage in children: aetiology, presentation and outcome.

We are aware of only few reports addressing spontaneous intracranial haemorrhage (SICH) in non-selected series of children. This is a retrospective analysis of clinical presentation and outcome in 34 children with SICH seen in the period 1990-2000 in our hospital. Traumatic, neonatal and subdural haemorrhages were excluded. The majority (47%, 16/34) of SICH was caused by an arteriovenous malformation (AVM). SICH was presented as an acute event in 53% (17/32) of patients. Forty-seven percent (15/32) of the cases had protracted courses, which made the diagnosis difficult. In our series, younger children had less specific symptoms. Mortality (25%, 8/32) and morbidity were considerable, particularly in infratentorial haemorrhages, in aneurysms, in children younger than 3 years and in those with underlying haematological disorders.
