 For the purpose of this dictation, the lowest visualized intervertebral disc space is labeled L5-S1. Multifocal vertebral body bony lesions replacing normal fatty marrow of the lumbar spine at the level of T11, T12, L1, L2, L3, L4, L5, Sacrum left alar more than right, as well as bilateral iliac bones (left more than right) with the demonstrating contrast enhancement indicating bony metastasis.In particular, L1 vertebral body shows about 15-20% of compression fracture and L4 vertebral body shows about 50% of compression fracture.Spinal cord signal intensity remains normal. However, at the level of L4, due to combined soft tissue mass of the metastasis as well as retroperitoneal of compression fracture fragment causing severe spinal stenosis at this level.The conus medullaris terminates at the L1 level.
1. Multilevel bony metastatic lesions involving lower thoracic, lumbar and sacral vertebrae as well as bilateral iliac bones.2. L1 and L4 compression fractures with severe spinal canal stenosis at the level of L4.
