title: Extramedullary Tumor of Cerebral Falx: An Unusual Presentation of Acute Megakaryocytic Leukemia.
abstract: In childhood acute myelogenous leukemia, extramedullary tumor is an occasional clinical symptom. However, extramedullary acute megakaryocytic leukemia is extremely rare. Here, we report an extremely rare case of acute megakaryocytic leukemia in a patient who presented with extramedullary tumor of cerebral falx as a first manifestation before the diagnosis of systemic bone marrow leukemia.
