RADIONUCLIDE CISTERNOGRAPHY IN SPONTANEOUS INTRACRANIAL HYPOTENSION

We report a case of spontaneous intracranial hypotension (SIH) that wa s investigated using cranial MRI and radionuclide cisternography, Radi onuclide imaging was remarkable, showing direct signs of diffuse asymm etric leakage and indirect signs of cerebrospinal fluid (CSF) hypotens ion consisting of slow CSF circulation to the convexity and rapid appe arance of urinary bladder activity, The MRI appearance was also sugges tive of SIH, with diffuse meningeal enhancement. Treatment with autolo gous blood injection at the level of the radionuclide spinal leakage w as useful, resulting in disappearance of SIH symptoms.
