myofibroblastic tumor（IMT）であった．IMTは筋線維芽細胞などの増殖や炎症細胞の浸潤を特徴とする中間悪性腫瘍であり，頭頚部，肺，縦郭，腹部軟部組織，消化管，泌尿生殖器などでの発生が報告されている．本症例のように腹腔内発生の報告は少ないため，画像所見と合わせて報告する．","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_full_name_3":{"attribute_name":"著者（英）","attribute_value_mlt":[{"names":[{"name":"Taisuke
