title: [Acute myelomonocytic leukemia with Inv(16) (p13 q22) relapsed in transverse myelopathy].
abstract: We report a case of AML (M 4) with eosinophilia who developed meningeal relapse and transverse myelopathy. A 37-year-old woman was admitted to our hospital because of lymphadenopathy and ecchymosis. One week prior to admission, she noticed swelling of the cervical lymph nodes and bleeding tendency. On admission, low-grade fever, gingival swelling, generalized lymphadenopathy, and ecchymosis on the lower legs were found. A white blood cell count was 93,900/microliters with 82% blast cells, and a platelet count was 24,000/microliters. A bone marrow was composed of 45.3% myeloblasts, 27% monocytes and 7.1% eosinophils. Chromosome analysis revealed inv(16). The diagnosis of M4Eo was made. About one year after she gained complete remission, she was readmitted because of disturbance of urination. There was a sign of transverse myelopathy at the seventh vertebral level, and blast cells were detected in the cerebrospinal fluid. Despite of radiation and chemotherapy, paresis of lower extremities and sensory disturbance were persistent, and the patient died on 52th hospital day.
