 Examination is motion degraded which limits assessment for subtle findings. Laminectomies are again seen from T6 to T9. Again seen is extensive long segment T2 signal abnormality involving the thoracic cord extending from approximately the T2 to the T12 levels not significantly changed in longitudinal extent since prior. Compared to examination from 2/18/2015, the expansile component of the signal abnormality appears to be improved. Many of the areas of T2 hyperintensity appear to be related to areas of cavitation with thinning of the cord parenchyma. Due to the motion degradation, the margins of the cord are difficult to define. There is evidence of adhesions in this thecal sac with areas of contour deformity of the cord and loculations of CSF. Shunt catheter is seen in the spinal canal at approximately the T9 level. There is a right pleural effusion which is again seen.T1 hyperintense lesions involving the T9 and T12 vertebral body are again seen. No suspicious osseous lesions. Vertebral body heights and alignment are grossly maintained. There is no significant spinal canal or neural foraminal stenosis at any level.
Again seen is extensive T2 signal abnormality involving the thoracic cord from approximately the T2 to the T12 levels. Although the longitudinal extent of the signal abnormality is not significantly changed, the expansile nature appears less evident when compared to prior study from 2/18/2015. Most of the extensive T2 signal abnormality in the cord on the current study has the appearance of cavitation/cystic myelomalacia. There is also evidence of adhesions in the thecal sac/arachnoiditis as seen before. Findings are compatible with sequela of infection.
