We describe a case of spontaneous intracranial hypotension secondary to a CSF-venous fistula that was treated with transvenous embolization. We present the imaging findings from a brain MRI before and after embolization demonstrating changes in the patient’s mamillopontine distance. Decreased mamillopontine distance is a marker of spontaneous intracranial hypotension and a minor criterion in the Bern Score.
