Unusual case of paraplegia.

Paraplegia due to a spinal cord epidural mass is an extremely rare presentation of undiagnosed leukemia. We are reporting a case of 14-year-old girl, who presented with paraplegia due to thoracic epidural mass, as the initial presenting manifestation of acute myeloid leukemia. Granulocytic sarcoma or chloroma should be considered in the differential diagnosis of an epidural mass in patients with or with out leukemia granulocytic sarcoma, which are rare extramedullary tumor-like proliferation of myelogenous precursor cells that may de novo precede acute leukemia or coincide with the first manifestation or relapse of acute myeloid leukemia.
