37 year old woman with history of tethered cord and pseudomeningocele, presenting with back pain. Again seen is evidence of spinal dysraphism and postsurgical changes related to multiple cord untethering and pseudomeningocele repair. Unchanged appearance of the low-lying cord with the distal neural tissue terminating at the S2 level with mild focal thickening which may be due to scarring. There is no significant change in contour of the expanded distal thecal sac. The position of the distal cord is unchanged with prone repositioning, which may represent cord retethering in the appropriate clinical setting. No syrinx is evident. A previously described focal fluid collection immediately dorsal to the thecal sac at the S2-S3 level is no longer present. Edematous changes affecting the subcutaneous tissues have improved, although are not completely imaged on today's examination. There is no new or enlarging fluid collection to suggest CSF leak. Alignment of the lumbar spine is anatomic. There is a normal lumbar lordosis. The vertebral body and disk heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated. A hemangioma within the L4 vertebral body is unchanged in appearance. There is no significant disk bulge, herniation, spinal canal or foraminal stenosis within the lumbar spine. Lower thoracic body Schmorl's nodes are again noted.
1.Interval resolution of a previously described focal fluid collection immediately dorsal to the thecal sac at the S2-S3 level. Mild persistent edematous changes affect the subcutaneous soft tissues overlying this region. 2.Unchanged appearance of the low-lying cord. The position of the distal cord is unchanged with prone repositioning, which may represent cord retethering in the appropriate clinical setting.
