前立腺癌の硬膜転移に続発した硬膜下水腫の1例

A Case of Subdural Effusion Secondary to Dural Metastasis of Prostatic Cancer: Case report

I．はじめに

　悪性腫瘍の硬膜への転移は，10-12％に認められているが6-8），硬膜転移に硬膜下血腫または硬膜下水腫が続発した症例の報告は，著者らが調べ得た限りでは，自験例を含め，文献上31例^1-5,10-22）に過ぎない．

　著者らは，前立腺癌の硬膜転移に続発した硬膜下水腫の1例を経験したので，若干の文献的考察を加えて報告する．

The authors reported a case of subdural effusion secondary to dural metastasis of prostatic cancer. A 61-year-old man was referred for headache, vomit-ing and gait disturbance. He had undergone hormonal therapy for prostatic cancer. He showed a mild left hemiparesis and anemia without bleeding. CT-scan dis-closed a multilobular crescent shaped low density area in the right hemisphere. Under the diagnosis of chronic subdural hematoma, burr hole irrigation therapy was performed. Xanthochromic fluid was evacuated from the subdural space, in which no tumor cells were shown to exist.
