Lumbar Epidural Varicose Vein: Early Neurological Improvement and Late Radiological Full Recovery with Surgery; The Importance of Magnetic Resonance Imaging in Follow-Up.

A lumbar epidural varicose vein is a rare clinical condition that can lead to neurological deficits. 3 types of lumbar epidural varicose veins were described according to the magnetic resonance imaging (MRI) findings: Type 1 is a thrombosed dilated epidural vein, type 2 is a non-thrombosed dilated epidural vein and type 3 is a sub-membraneous epidural hematoma. Enlarged epidural venous plexuses must be decompressed if they have lead to a neurological deficit. Surgical treatment is by excision or disrupting the cyst's integrity. We present a case of lumbar epidural varicose vein that was surgically treated twice and showed no radiological change despite the disruption of integrity with a partial excision. The lesion spontaneously and completely disappeared in the late period. We emphasize the importance of MRI in follow-up.
