Sagittal T1-weighted MRI scans of the cervical-thoracic (A) and thoracic-lumbar (B) regions demonstrating a hyperintense epidural posterior lesion, extending from T1 to T12 vertebral level. Axial T1 (C) and T2-weighted (D) MRI scans demonstrated marked spinal cord compression. The epidural lesion was isointense on the sagittal T1 fast suppression sequence (E).

T-4 to T-12 vertebral bodies (Fig. 1). This mass had a maximum thickness of 10 mm in the middle, tapering at both the T-4 and T-12 vertebral bodies, and the spinal cord appeared to be displaced and compressed anteriorly against the posterior aspect of the vertebrae, with a significant reduction in the AP diameter of the spinal cord.
Photomicrograph of the histopathological examination of the surgical specimen demonstrated mature adipose tissue with surrounding fibrous tissue (H & E, X400).

Histological examination of the operative specimen demonstrated vascularized mature fibro-fatty tissue consistent with the diagnosis of lipomatosis (Fig. 2).
Postoperative sagittal T1 (A) and T2-weighted (B) MRI images after laminoplasty and complete excision of SEL demonstrating no recurrence.
