原発心臓粘液肉腫の脳転移例

Brain Metastases from Primary Cardiac Myxosarcoma:Report of a Case

Ⅰ．はじめに

　心臓原発腫瘍は稀なものであるが^5,11,19），そのうちでも，粘液肉腫は非常に稀である^3,5,16,21）．一方，転移性脳腫瘍の原発巣を心臓と確認した報告もまた極めて稀である．今回われわれは，心臓原発粘液肉腫の脳転移例を経験したので，若干の考察を加え報告する．

A very rare case of a myxosarcoma with metastases to the brain is reported.

A 33-year-old female was admitted to our hospital because of lassitude, fever, slight left hemiparesis, headache and other signs of intracranial hypertension and cardiac symptoms such as dyspnea and palpitation. She had the cardiac symptoms once 14 years before, which reappeared and rapidly aggravated two months before the admission. Cerebral angiography revealed a mass in the right temporal lobe and physical and laboratory examinations revealed mitral value failure and hyperthyroidism.
