Intracranial hemorrhage in children with idiopathic thrombocytopenic purpura.

Intracranial hemorrhage is a rare but life-threatening complication of childhood idiopathic thrombocytopenic purpura. We present three cases of this complication encountered at our institution, in addition to a tabulation of 15 previously reported cases. Prevention, diagnosis, and management of intracranial hemorrhage in idiopathic thrombocytopenic purpura are discussed. The importance of avoidance of antiplatelet drugs as well as the significance of the location of the intracranial hemorrhage are emphasized. Posterior fossa hemorrhages are especially dangerous because of the possibility of rapid cerebellar herniation and brainstem compression. Management of intracranial hemorrhage should be prompt and aggressive, and splenectomy should always be performed prior to any neurosurgical procedure. It is encouraging that 11 of 18 patients had a favorable outcome.
