T1-weighted sagittal (a) and T2-weighted coronal (b) images. Arrow points that the lipoma is located at the same level of the ectopic extremity. Medulla Spinalis terminates between L3 and L4 vertebrae. Ectopic extremity originates from subcutaneous soft tissues and it does not extend deeper neural elements. It ends interspinous ligament. Coronal T2-weighted image shows dorsally located extremity, composed of fat and muscle tissue. Note that cerebral structures are in normal limits.
