Idiopathic epidural lipomatosis of the lumbar spine

Magnetic resonance imaging (MRI) of the lumbar spine showed a multilevel high intensity epidural mass lesion compressing the dural sac extending from L1 to L5 level, on T1 and T2 weighted images (WI) (A & B). Figure 1 (A) sagittal T1 weighted images MRI shows posterior and anterior epidural adipose tissue compressing the dural sac extending from L1 to L5 segment with high signal intensity; (B) sagittal T2 weighted images MRI featured multilevel high intensity epidural mass lesion compressing the dural sac; (C) axial T2 weighted images MRI noticed a hyperintense anterior epidural mass with deformation of the dural sac; (D) frontal MRI myelography shows complete stop of the cerebro-spinal fluid on the lumbar spine 1 El Manar, Tunis University, Faculty of Medicine of Tunis, Department of Neurosurgery, Burns and Trauma Center, Ben Arous, Tunisia 2 Rhumatology Department, Kassab Institute, Manouba, Tunisia
