MRI of lipomyelomeningocele
Sagittal T1 (left), T2 (middle) and T1 with contrast (right) MRI of the lumbar spine show a low-lying conus medullaris at the level of S2, which ends in a lipomatous mass that via a defect in the bone is contiguous with the subcutaneous fat posteriorly.

The diagnosis was lipomyelomeningocele.
