Abstract

拍動性耳鳴を主症状とした側頭骨グロームス腫瘍の3症例を報告した. 全例に手術のみを施行し, 放射線治療は用いなかつた. CT, MRI, 血管造影で術前診断ができた鼓室型腫瘍, 頸静脈球型腫瘍に対しては腫瘍全摘出術が可能であつたが, 画像診断が不十分で頸静脈球型か鼓室型か鑑別困難であつた初期の1例では再発をきたした. 診断には問診, 耳鏡所見の他, インピーダンスオージオメトリーの所見も参考になるが, 治療を行うにあたつてCT, MRIなどの画像診断による腫瘍伸展範囲の術前評価が重要であることがわかつた.

Three patients with glomus tumor who presented complaining of pulsatile tinnitus were treated by surgery. They included one case each of glomus tympanicum, glomus jugulare, and glomus jugulotympanicum, in which the clinical distinction between the tympanicum extension of the glomus jugulare tumor and the jugular fossa extension of the glomus tympanicum tumor had been difficult. Although the first 2 cases underwent a successful total tumor removal, the latter case had to undergo a repeated partial tumor removal because the initial surgery had been completed before conducting accurate radiological examinations. Based on the above findings, both high resolution CT and MRI help to identify the most appropriate surgical treatment.
