4 yo with urinary retention, evaluate for tethered cord Five lumbar type vertebral bodies are presumed to be present with the most inferior well-defined disc labelled L5-S1. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is normal. The conus medullaris is borderline low in position at the L2-3 level. Prone images demonstrate appropriate anterior motion of the conus. No evidence of filar lipoma or other masses within the lumbar spinal canal.No significant disc disease. No spinal canal or neural foraminal stenosis at any level.Bilateral hydronephrosis right worse than left noted and better assessed on recent ultrasound studies.
No convincing evidence of tethered cord. The conus medullaris is at the L2-3 level which is at the lower limits of normal. Prone images demonstrate appropriate anterior motion of the conus. No evidence of filar lipoma or other masses within the lumbar spinal canal.
