We report the clinical, radiologic, and pathologic findings of a case of inflammatory pseudotumor in an otherwise healthy 44-year-old woman, who presented with dysuria and hematuria causing hemodynamic instability. Computed tomography revealed a 4.3-cm by 3.5-cm densely enhancing mass arising from the anterior bladder wall. Pathologic examination showed spindle-shaped cells with mild nuclear pleomorphism, rare mitotic activity, and a strong reaction to vimentin, with focal positivity to alpha-actin and S100 protein. Monokeratin, CK7, and CK20 were negative. After two transurethral resections, the patient underwent partial cystectomy.
我们报告了一例炎性假瘤患者的临床、影像学和病理学检查结果。该患者为一名44岁健康女性，因排尿困难和血尿导致血流动力学不稳定。计算机断层扫描显示，一个4.3厘米×3.5厘米的肿块从前膀胱壁长出，强化明显。病理检查显示梭形细胞，核轻度异形，有罕见的有丝分裂活性，波形蛋白反应强烈，α-肌动蛋白和S100蛋白呈局灶性阳性。单克隆角蛋白、CK7和CK20均为阴性。经过两次经尿道切除术后，患者接受了部分膀胱切除术。
