再発病巣が化学療法のみで消失した腎癌の転移性脳腫瘍の1例

A Case of Recurrence of a Metastatic Brain Tumor which Disappeared due to Chemotherapy Only

I．はじめに

　転移性脳腫瘍の原発巣としては肺が最も多く，腎臓は約4％を占めるとされている．いずれにしても予後は不良であり進行期症例の治療は絶望的と言える．今回われわれは腎細胞癌の脳転移に対し開頭術を行い，その後脳腫瘍が再発したものの，化学療法のみで消失した症例を経験したので報告する．

Abstract

A rare case of recurrence of a metastatic brain tumor which disappeared due to chemotherapy only is re-ported. A 52-year-old male was noticed to have an abnormal shadow in his chest X-P at a routine medical examination, so a close examination was made. He was diagnosed as having right renal cell carcinoma which had metastasized to the lung. He was treated by intra-arterial infusion of anti-cancer drugs and embolization of the right renal artery. No renal symptom was seen, growth of the primary tumor stopped, and the abnor-mal shadow in his chest diminished.
