A CASE OF SKULL METASTASIS OF MALIGNANT STRUMA

緒言

　甲状腺癌の頭蓋骨転移は比較的稀なものであるが，その多くは頭部外面にもり上る半球状の腫瘤であり，その外観に特長があるものである。われわれは最近，頭蓋内圧亢進症状を主訴として来院した珍らしい経過をとつた1例を経験したので報告する。

A rare case of skull metastasis of malignant struma was reported. A 62-year-old female who had been operated for struma two times ( 2 and 4 years ago) admitted because of semicomatous state and hemiparesis on her right side.

Skull defect was found at the left temporo-parietal region on a plain film and the left carotid angiogram revealed the tumor stain which mainly grew intra-cranial space and was fed through the external carotid artery at the same region. Skull metastasis was totally removed, but the postoperative scintig-ram by radioiodine revealed other metastasis at the skull, the both lung, the 12th chest vertebrae and the pelvis. Operation was performed for the chest vertebrae and the inner or the outer radiation therapies by ¹³¹I or ⁶⁰Co were done for the others. Patient is now alive and well about 2 years after last operation.
