Abstract

術前に縦隔腫瘍と診断した症例を手術し,奇静脈瘤であったので文献的考察を交え報告する.<br> 症例は43歳,女性.背部痛を主訴として来院,当初は白血球増多などの炎症所見があったが,まもなく消失した.各種画像診断の結果,神経鞘腫がもっとも疑わしい縦隔腫瘍として手術に望んだ.<br> 開胸すると,軟らかい腫瘤が奇静脈背面にあり,奇静脈との癒着が強固なため,合併切除した.病理組織学的には腫瘤は嚢状で,壁は3層構造であった.筋層が縦走しており,弾性板は認めなかったので,拡張した静脈血管と診断された.内腔は血栓が充満していた.<br> 術後13カ月の現在健康である.

The following is a case report of a large aneurysm probably arising from the azygos vein. A 43-year-old woman was admitted to the hospital because of dorsalgia.<br> After examinations including plain film of X-ray, ultrasonography, computed sonography, and magnetic resonance imaging, thoracotomy was performed under a diagnosis of suspected neurinoma in the posterior mediastinal space. There was a cystic tumor behind the azygos vein, that was 50×39×30mm in size without pulsation and the content was conjectured fresh clot. The cyst with the azygos vein was excised because of severe adhesion between them. Postoperative course was uneventfull. Microscopically the wall of the aneurysmal portion showed three layers of the venous structure.<br> Postoperative course is uneventfull.
