History of relapsed AML status post transplant with back pain. Thoracic Spine: There is diffuse vertebral bone marrow T1 and T2 hypointensity. There is degenerative disc disease in the cervical spine seen on sagittal view without evidence of cord compression. There is no intrathecal hematoma, abscess, or tumor deposit. However, there is posterior epidural lipomatosis at multiple levels, measuring up to 10 mm in thickness and resulting in anterior displacement of the spinal cord and marked effacement of the intrathecal cerebrospinal fluid. Nevertheless, there is not convincing spinal cord deformity or signal abnormality. The vertebral column alignment is anatomic. The vertebral body heights are preserved. There is diffuse subcutaneous edema.Lumbar Spine: There are partially-imaged geographic heterogeneous areas in the bone marrow of the bilateral sacral ala and iliac bones. Otherwise, there is a background of diffuse T1 and T2 vertebral bone signal hypointensity. The conus is normal in morphology and terminates at L1 level. There is a posterior disc-osteophyte complex at the L4-5 level without significant spinal canal or neural foraminal stenosis. There is lack of the usual lordosis, but no spondylolisthesis. The vertebral body heights are preserved. There are bilateral renal cysts. There is diffuse subcutaneous edema.
1. Diffuse bone marrow signal abnormality related to leukemia. Partially-imaged heterogeneous bone marrow of the bilateral sacral ala and iliac bones may also be related to leukemia and/or treatment effects, although osteonecrosis is a potential consideration. Please refer to the separate pelvis MRI report for additional details.2. Epidural lipomatosis in the thoracic spine associated with multilevel spinal canal narrowing.3. Mild degenerative disc disease at the L4-5 level without significant spinal canal or neural foraminal stenosis.
