Spinal epidural venous engorgement-Potential imaging confounder after diagnostic lumbar puncture.

Intracranial hypotension is a result of low Cerebrospinal fluid (CSF) pressure caused by either spontaneous or postoperative leakage. The classic presentation of spontaneous intracranial hypotension is acute orthostatic headache, but the diagnosis can sometimes be challenging as some patients may present with atypical initial presentations including cervical pain as well as cervical radiculopathy secondary to cervical spine venous engorgement. We described a 42-year-old female patient who presented initially with neuropathic pain symptoms as well as weakness involving both lower extremities for which she underwent diagnostic lumbar puncture with concern regarding demyelinating neuropathy. However, subsequently she developed postural headache as well as severe cervical pain which was attributed to cervical epidural venous engorgement in setting of intracranial hypotension based on cervical spine magnetic resonance imaging (MRI) findings. She was managed conservatively, and repeated cervical spine MRI 3 days later showed prominent improvement in the imaging findings. Spinal epidural venous engorgement can occur secondary to intracranial hypotension (mainly post lumbar puncture), and can present clinically with neck pain or even symptoms of radiculopathy. Since the findings can mimic more serious conditions, it is extremely important to consider this condition in the differential diagnosis of an enhancing epidural collection in the cervical spine, particularly when intracranial hypotension is suspected.
