 The thoracic spine is in normal alignment, with a normal thoracic kyphosis. The vertebral body and disk heights are well-maintained. The thoracic vertebral bodies are mildly heterogeneous related to focal fat deposition. Multilevel degenerative changes are present. No worrisome focal marrow signal abnormality is appreciated. At upper T4 vertebral level, there is a 2 mm focus of T2 signal along the left paramedian ventral cord, nonspecific. The spinal cord is slightly ventrally displaced at T4 with slight cord flattening in the AP dimension. Otherwise, spinal cord is of normal caliber and signal. The paraspinal soft tissue structures are unremarkable.At C6-C7 and C7-T1: There is mild left foraminal disc protrusion with resultant mild left neural foraminal narrowing. No spinal canal stenosis.At T4-T5, there is left paracentral/foraminal disc extrusion which extends 2 mm cranially, indenting the ventral thecal sac, resulting in mild left neuroforaminal narrowing. There is no spinal canal stenosis.T10-11: There is a small left paracentral disc protrusion without significant neural foramina or spinal stenosis.Remaining thoracic intervertebral disc levels show no significant disk bulge, herniation, spinal canal or foraminal stenosis.MRI lumbar spine: Motion limited exam. The lumbar spine is in normal alignment, with a normal lumbar lordosis. The vertebral body heights are well-maintained. Mildly heterogeneous marrow signal related to focal fatty position. No worrisome focal marrow signal abnormality is appreciated. There is minimal loss of disc height at L5-S1 with disc desiccation. Remaining intervertebral disc heights are maintained. The distal spinal cord and conus are within normal limits with the conus terminating at the L1-L2 level. The paraspinal soft tissue structures are unremarkable.T11-T12: No significant disc disease or stenosis.T12-L1: No significant disc disease or stenosis.L1-L2: No significant disc disease or stenosis.L2-L3: Mild disc bulge which shallow left foraminal protrusion resulting in mild left neural foraminal narrowing. No spinal canal stenosis.L3-L4: Mild degenerative facet disease. No significant disc disease or stenosis.L4-L5: Mild degenerative facet disease. Minimal disc bulge and minimal bilateral neural foraminal narrowing.L5-S1: Facet arthropathy. Mild disc bulge with superimposed left foraminal disc protrusion with moderate to severe left neural foraminal narrowing, which may abut the exiting left L5 nerve root. Mild right neural foraminal narrowing. No spinal canal stenosis.There is linear area opacity in the right lung base may represent subsegmental atelectasis.
1. No evidence of spinal canal stenosis in the thoracic or lumbar spine.2. Mild degenerative spondylotic changes in the thoracic spine, mostly at T4-T5 resulting in mild left neural foraminal narrowing.3. Punctate focus of T2 signal abnormality in the left ventral cord at upper T4 vertebral level is nonspecific, but may represent mild myelomalacia. This likely relates to the incidental ventral displacement of the thoracic cord at T4 level with mild cord flattening and narrowing. Possibility of intradural extramedullary cystic focal lesion such as arachnoid cyst, versus ventral cord herniation is suspected. 5. Degenerative disc changes in the lumbar spine, worst at L5-S1, where there is disc bulge with superimposed left foraminal disc protrusion reflecting moderate left neural foraminal narrowing and possibly abutting the exiting left L5 nerve root. Correlate for left L5 radiculopathy.
