This case report highlights the aggressive clinical course and poor prognosis of a rare abdominal aortic intimal sarcoma presenting as a pseudoaneurysm, despite surgical resection and adjuvant chemo-radiotherapy.
May warrant vigilant post-resection surveillance for pseudoaneurysm in aortic sarcoma; extends sparse case-based evidence on this rare tumor.
要 旨：仮性瘤を形成して発症した48歳男性の腹部大動脈原発腫瘍を経験した。造影CT・MRI所見にて大動脈原発悪性腫瘍と診断し，破裂予防目的に，腫瘍切除と腹部大動脈の再建を行った。組織学的には，未分化な間葉系腫瘍で，血管内膜に沿った進展を示すことからintimal sarcomaと診断した。外照射と化学療法を追加したが術後12カ月で多発肺転移が出現し，術後35カ月目に吻合部動脈瘤の破綻にて永眠した。画像・病理・剖検所見とともに臨床経過を報告する。
