Intracerebral hemorrhage as a rare complication of imatinib in a Philadelphia chromosome positive acute lymphoblastic leukemia pediatric patient.

Imatinib is a BCR-ABL tyrosine kinase inhibitor used for the treatment of a variety of diseases including Philadelphia chromosome positive (Ph+) leukemia. We report a 15 year old male patient presenting with symptomatic acute intracerebral hemorrhage (ICH) in midbrain while on imatinib more than three years after completion of therapy for Ph + B-ALL. The patient denied recent trauma history and consumption of other medication. Laboratory findings did not show any signs of relapse, coagulopathy nor thrombocytopenia. Under the impression of imatinib related ICH, imatinib was discontinued and with conservative management the patient recovered without neurologic sequalae. This case demonstrates the first pediatric case of spontaneous ICH as a rare complication of imatinib.
