A Rare Case of Immune Thrombocytopenia With Intracranial Hemorrhage Secondary to Cavernous Malformation.

Immune thrombocytopenia (ITP) is an autoimmune disease resulting in a fall in platelet count, causing ecchymoses and bleeding manifestations. The most prevalent acquired bleeding disorder in children is ITP. Intracranial hemorrhage (ICH) is a rare but most devastating complication of ITP which can cause neurological sequelae. We report the case of a four-year-old male child who presented with a history of seizures, headache, multiple ecchymoses, and bruising. Blood counts and bone marrow examination were suggestive of ITP. Magnetic resonance imaging (MRI) of the brain showed ICH with multiple cerebral cavernous malformations. ICH as the first presentation of ITP is extremely rare. ICH in a case of ITP secondary to arteriovenous malformation has been scarcely reported, establishing the rarity of the currently presented case. Morbidity and mortality of ICH occurring as a consequence of ITP can be reduced by recognizing the symptoms, diagnosing promptly, and treating aggressively.
