Granulocytic sarcoma in childhood acute myelogenous leukemia.
A 12-year-old boy with acute myelogenous leukemia developed acute weakness and paresthesias of the lower extremities after lumbar puncture. Computed tomography and magnetic resonance imaging revealed 2 large paraspinal masses (granulocytic sarcoma) causing spinal cord compression. Treatment with corticosteroids, radiation therapy, and chemotherapy caused complete resolution of symptoms; there was no evidence of tumor on subsequent magnetic resonance imaging or at autopsy. Granulocytic sarcomas (chloromas) rarely involve the nervous system in patients with acute myelogenous leukemia, although with increased survival it is apparent that the incidence may be greater than previously believed. Central nervous system prophylaxis was not administered to our patient but may be recommended for future patients if systemic disease can be controlled. General features of central nervous system complications of acute myelogenous leukemia, characteristics of granulocytic sarcoma, and review of current radiographic techniques used in the evaluation of these tumors are discussed.
