A 32 year-old-man with a history of acute myeloid leukemia on remission for one year presented with sudden back pain, weakness and reduced sensation in both legs, and urinary incontinence that had progressed over one weak. MRI of thoracic and lumbar spine was performed on a 1.5 T system using a body coil due to his neurological symptoms. T1-weighted sequence (TR/TE: 617/15 mse) and T2-weighted sequence (TR/TE: 4300/110 mse) on sagittal and axial images with 3 mm slice thickness were used. Gadolinium enhanced T1-weighted axial images were obtained. Magnetic resonance imaging (MRI) demonstrated spinal cord compression by epidural extramedullary hematopoietic tissue. Spinal epidural space is a very rare site for extramedullary hematopoiesis.
