AB  - SUMMARY: Post–dural puncture headache is an increasingly recognized cause of chronic headache. Outside of clinical history and myelography that requires an additional dural puncture, there is no reliable diagnostic test to evaluate for persistent dural defects. We describe the injection of iodinated contrast into the dorsal epidural space under CT guidance in 5 patients as a potential tool to visualize persistent dural defects.DSMdigital subtraction myelographyPDPHPost–dural puncture headacheSIHspontaneous intracranial hypotension
