The spinal cord shows normal caliber and signal intensity but extends abnormally low, reaching down to the level of L5 (tethered). Between L2/3 and S1, a fatty mass is shown dorsal to the distal cord and contiguous with subcutaneous fat. The mass extends over a distance of 5.6 cm craniocaudal. Superiorly it is a little more prominent to the right of the cord than to the left.
Findings in keeping with a lipomyelocele with tethered cord.
