Giant cervical epidural veins after lumbar puncture in a case of intracranial hypotension

A 29-year-old woman presented with dilated epidural veins and incapacitatin g headache after undergoing a lumbar puncture. Two months later, the result s of follow-up MR imaging were normal. These findings suggest that temporar y dilation of the epidural vein may occur in association with post-lumbar p uncture intracranial hypotension syndrome. In these cases, it seems useful to confirm whether the patient has recently undergone a lumbar puncture.
