Abstract: 76歳男性.患者は頻尿により受診し,尿沈渣はWBC 10~19/hpf,抗生剤を投与していた.だが,下腹部から尿道の不快感持続で,CTにて左腹壁から膀胱までの充実成分・嚢胞性成分の混在する腫瘤を認め,尿管膜腫瘍を疑い,今回入院となった.腹部造影CTでは左腹直筋から膀胱の前壁から頂部に連続した充実成分と嚢胞性成分の混在する腫瘤を認め,MRIでは更に恥骨,前立腺にも連続し,T1で低吸収,T2で高吸収像であった.一方,注腸検査ではS状結腸への浸潤像を認め,これらより感染性尿膜管腫瘍の膀胱・S状結腸浸潤と診断し,腫瘍摘出術を施行した.術後経過は良好で経口摂取,歩行も可能であったが,術後2週間後に下肢の浮腫を認め,精査で深部静脈血栓を認めて抗凝固療法,IVCフィルター留置と予防策をとったが,3週後に肺梗塞で死亡した.なお,病理所見では腹膜デスモイドと診断された.
A 76-year-old male patient complained of frequent urination. Computed tomographic and magnetic resonance imaging scans revealed a heterogeneous mass involving his bladder, prostate and Sigmoid colon. He was diagnosed with an invasive urachal tumor and surgery was performed due to severe tumor adhesion to adjacent organs. Partial resection of the tumor was performed with partial cystectomy and sigmoidectomy. A post-operative pathological diagnosis revealed the tumor was a desmoid abdominal wall tumor. The desmoid abdominal wall tumor was not easily differentiated preoperatively from an urachal tumor.
