 There is multifocal low T1 and T2 signal in the dorsal epidural space from the T4-T9 levels, which may represent ossification along the ligamentum flavum. There is associated severe spinal canal stenosis from the T4-T5 to T6-T7 levels with flattening of the cord and suggestion of high T2 signal within the spinal cord. There is no high-grade spinal canal stenosis in the cervical or lumbar spine.There is prominence of the lumbar dorsal and ventral epidural fat from the L3-S1 levels, along with narrowing of the distal spinal canal, which may be suggestive of epidural lipomatosis and possible developmental narrowing of the spinal canal. Additional note is made of prominent facet arthropathy, particularly at the L4-5 and L5-S1 levels.The vertebral bodies are appropriate in overall alignment and height.
1. This is a limited exam specific for the exclusion of cord compression only. There is multifocal decreased T1 and T2 signal in the dorsal epidural space from the T4-T9 levels, which may represent ossification along the ligamentum flavum. There is consequent severe spinal canal stenosis, flattening of the cord and suggestion of high signal within the spinal cord at these levels. Recommend dedicated MR of the thoracic spine; CT of the thoracic spine would also be useful.2. Findings suggestive of developmental narrowing of the lower lumbar spinal canal with epidural lipomatosis.
