Myeloid sarcoma occurs in 1% - 9% of patients with myelogenous leukemia. Spinal epidural myeloid sarcoma is particularly rare, and its treatment has not been established. A 27-year-old woman complained of pain on her left chest, back around the scapula, and neck. Magnetic resonance imaging (MRI) showed a thoracic epidural tumor. One week after her visit, she developed motor weakness of her lower extremities and dysuria, and she was diagnosed with acute myelogenous leukemia (AML) on peripheral blood analysis. The epidural tumor was strongly suspected to be myeloid sarcoma. The paralysis of the lower extremities and bladder dysfunction were not progressive, and chemotherapy and local radiation therapy to the spine were performed. Improvement of paralysis and complete reduction of tumor volume were achieved by the combination of local low-dose radiation therapy and chemotherapy.
