Lumbar Intraspinal Osteolipoma Presenting as Cauda Equina Syndrome: A Case Report and Review of Literature

Figure 2

(a and b) T2- and T1-weighted sagittal MRI images showing a large epidural intraspinal posterior epidural lesion with hyperintense signals in the periphery and hypointense signals at the center at the L2-L3 level with severe thinning of the thecal sac. The hyperintense region becomes hypointense in the fat-suppressed sequence (c) confirming the presence of fat in the periphery and bone tissue in the center of the lesion. (d and e) Axial images demonstrating adjacent epidural fatty hypertrophy contributing to stenosis in addition to the lesion reducing the caliber of dura to near nonexistence.
