Recent reexploration of lumbar laminectomy for untethering of spinal cord and history of tethered cord previously released in 2011. There is partial sacralization of the L5 vertebra. There are postoperative findings related to reexploration of lumbar laminectomy for untethering of spinal cord, with fluid in the posterior paraspinal soft tissues along the incision plane. There is no significant interval change in the lipomatous lesion associated with the conus terminalis, which displays a blunted morphology and is situated at the L2 level. There is mild diffuse enhancement along the conus medullaris and portions of the cauda equina nerve roots. Patchy low T1 and T2 signal posterior to the conus likely represents CSF flow artifact versus less likely hemorrhage. There is no appreciable translation of the conus medullaris with prone imaging. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis.
Recent postoperative findings related to reexploration of lumbar laminectomy for untethering of spinal cord without appreciable translation of the abnormal conus with associated lipomatous malformation. The presence of mild diffuse enhancement along the conus medullaris and portions of the cauda equina nerve roots is likely within the expected limits of recent surgical effects, although superimposed infection cannot be entirely excluded on the basis of imaging alone.
