MRI (Mass of the Back/Minimal Spinal Dysraphism)

16.6-year-old teenager with a subcutaneous lipoma over the sacrum. Sagittal MRI slice with the dural sac and the spinal cord. Over the sacrum there is a large subcutaneous mass entering the dural sac by a stalk and ending in a mass connected to the conus. The diagnosis is a large subcutaneous lipoma in the region of the sacrum, which is part of a minimal spinal dysraphism connected to a lipoma of the conus and may lead to compression and tethering of the conus. The MRI yields informations about the topography, composition, and extension of the lipoma.
