Abstract
OBJECTIVE: To investigate clinical, MRI, and radioisotope findings and therapeutic outcome of the syndrome of CSF hypovolemia. METHODS: Retrospective review was performed of 30 consecutive patients (10 men, 20 women; mean age 37 years) with the syndrome of CSF hypovolemia. RESULTS: All patients had an orthostatic headache, which was alleviated to a variable extent on recumbency. Additional clinical symptoms included nausea, dizziness, neck stiffness, blurring of vision, tinnitus, plugged ear, hearing difficulties and radicular pain of the arm. Eighty-two percent of the patients had CSF opening pressure less than 60 mm H2O, 59% had CSF pleocytosis, and 95% had increased CSF protein. Brain MRI showed diffuse pachymeningeal gadolinium enhancement on T1-weighted image in 83%, which was seen as hyperintense signals on T2-weighted imaging. Other features included subdural hematoma/hygroma in 17% and descent of the brain in 48% of the patients. Radioisotope cisternographic results identified CSF leakage sites in 52%, most often at the lumbar region. Also observed were limited ascent of the tracer to the cerebral convexity (91%), early appearance of radioisotope in the bladder (65%), and early soft tissue uptake of radioisotope (43%). Epidural blood patches were performed in 23 patients, which produced complete resolution of headaches in 70%. Two patients underwent drainage of subdural hematoma. None died or were disabled during hospitalization. CONCLUSIONS: Patients with CSF hypovolemia frequently have distinct MRI and radioisotope cisternographic abnormalities and often respond favorably to an epidural blood patch.
