Giant Cervical Epidural Veins after Lumbar Puncture in a Case of Intracranial Hypotension

Summary: A 29-year-old woman presented with dilated epidural veins and incapacitating headache after under-going a lumbar puncture. Two months later, the results of follow-up MR imaging were normal. These findings suggest that temporary dilation of the epidural vein may occur in association with post-lumbar puncture intracranial hypo-tension syndrome. In these cases, it seems useful to confirm whether the patient has recently undergone a lumbar puncture. Giant cervical epidural veins are rarely seen on imaging studies. In most cases, major enlargement has been caused by an unknown arteriovenous mal-formation or a jugular vein thrombosis. We present a rare case of cervical epidural vein dilation. Case Repor
