Abstract
Radionuclide cisternography can demonstrate cerebrospinal fluid (CSF) leakage in some cases of the spontaneous intracranial hypotension syndrome. If symptoms do not disappear spontaneously after rest, epidural blood patching usually follows with good results. Cisternography often provides the only indirect signs of leakage with early bladder and/or slight cranial activity. We present a case of a 56-year-old man with a posterior thoracic CSF leak demonstrated by Tc-99m diethylenetriaminepentaacetic acid (DTPA) cisternography. The extraspinal radioactivity was visible after the patient was supine for several hours and disappeared after a short time of standing, providing direct evidence of a CSF leak.
