両側慢性硬膜下血腫を伴った特発性低髄液圧症候群（脳脊髄液減少症）

抄録

We present a case of bilateral chronic subdural hematoma due to spontaneous intracranial hypotension. This patient complained of postural headache. Computed tomography of the brain showed bilateral chronic subdural hematomas, and radioisotope cisternography showed leakage of cerebrospinal fluid at the lumbar level. We placed an epidural blood patch at the lumbar level and a few days later performed irrigation of the bilateral hematomas. The patient recovered completely and was discharged.
