Intracranial hypotension due to cerebrospinal fluid leakage detected by radioisotope cisternography.
Seven patients, six females and one male aged 26 to 39 years old, presented with headache in the upright posture, which was completely relieved in the recumbent posture. Radioisotope cisternography with technetium-99m-human serum albumin detected cerebrospinal fluid (CSF) leakage at the cervicothoracic level in six patients, and at the high cervical level in one patient. The diagnosis was intracranial hypotension due to spontaneous CSF leakage. Complete bed rest for more than 2 weeks resulted in complete resolution of the headache in all patients, and follow-up cisternography showed no leakage. Radioisotope cisternography is useful for the diagnosis of spontaneous CSF leakage, and complete bed rest for more than 2 weeks may be the best method of treatment.
