Objective: We report an unusual case of spontaneous intracranial hypotension caused by a spontaneous spinal CSF leak. The patient was successfully treated with a spinal epidural blood patch.
Methods: A 49-year-old woman presented with severe headache and nausea caused by bilateral subdural hematomas (SDH). She underwent bilateral burr-hole evacuation twice. We performed spinal MR imaging in the diagnostic work-up and found an epidural fluid collection along the whole spinal canal. Further evaluation by CT myelography demonstrated the precise position of the CSF fistula at Th1 ventromedially. The patient was successfully treated with an epidural blood patch which was placed under CT guidance.
Results: The initial complaints and neurological deficits resolved completely. The follow-up cranial CT scan 1 month after the blood patch procedure demonstrated complete resolution of the SDH. Furthermore, spinal MR imaging showed a significant fluid reduction in the spinal canal.
Conclusions: In young patients with recurrent cranial SDH, spontaneous intracranial hypotension caused by a spinal CSF fistula should be taken into consideration. An epidural blood patch is the initial procedure of choice in this entity.
