くも膜のう胞の合併が疑われたパニック障害の1症例

Abstract

Arachnoid cyst is a benign tumor that is satisfied in cerebrosplnal fluid, and it arises in the subarachnoid cavity. Though it is often asymptOmatic, increased intracranial pressure and convulsive seizure may rarely be combined. We report a rare case of panic disorder where a combination with arachnoid cyst was suspected. The patient (a48-year-old female) was admitted to our psychiatric ward for the treatment of panic disorder. Arachnoid cyst in mega cisterna magna was indicated by brain MRI, and this was thought to be pressing on the cerebellum. She was treated with medication (alprazoram, setiptiline) and behavioral therapy. As a result, her anxiety symptoms gradually improved. Since she had complained of morning headache during hospitalization, this headache might have been induced by the arachnoid cyst. The cyst might have affected panic disorder and careful observation is also required for the future.
