 There is no evidence of cord compression.There is straightening of the entire spine in the sagittal plane with dextroscoliosis of the lower thoracic spine.Conus terminates at approximate mid-L1 level. There is a diffuse plaque-like T1 hyperintensity along the dorsal thecal sac from the level of L1-L2 that becomes thicker caudally to the end of the thecal sac. The maximal thickness is 9 mm. At the level of L5 there is additional ventral thecal sac T1 hyperintensity. There is corresponding drop out of signal on STIR, suggesting that the intrathecal finding is fat. There does not appear to be true layering of the abnormal signal in the thecal sac to suggest blood products, although axial images are not available.Annular fissure is seen at L4-L5. There is desiccation of the L4-L5 disc. Diffuse desiccation is seen in the cervical disks.
1. No evidence of cord compression.2. Probably fatty filum/lipoma in the lower lumbar spine. Recommend dedicated lumbar spine MRI on nonurgent basis to include prone imaging for further evaluation.3. Mild spondylotic change of L4-L5.
