A Case of Cerebrospinal Fluid Hypovolemic Syndrome with Impairment of the Level of Consciousness

We report a 39-year-old man who had newly developed a postural headache followed by a progressive decline in his level of consciousness with behavioral changes. Magnetic resonance imaging of the brain and radioisotope cisternography revealed typical findings of cerebrospinal fluid (CSF) hypovolemic syndrome combined with bilateral subdural hematoma and diencephalic compression. His headache and mental status improved after repeated epidural blood patches. Early detection of this rare complication and rapid treatment such as blood patches are very important in the treatment of these patients.
