膀胱炎症性假肉瘤(假瘤)是一种罕见疾病,是一种良性病变,放射学和膀胱镜检查同恶性中胚层膀胱肿瘤不能区别,仅在病理检查时方可明确诊断。作者报告两例并复习文献,描述其CT及临床和病理学表现,据作者所知在英国肿瘤学、病理学和泌尿学文献中已有9例报告,但放射学文献尚无报告。例1,女,55岁,间歇性耻骨弓上痛和尿频2个月入院,镜下血尿,按尿路感染行抗生素治疗、物理检查未见异常,CT增强在膀胱底前壁发现7-8cm增强性坏死性肿块,肿块侵及膀胱周围组织和邻近的腹直肌,大体病理检查证实了CT所见,另外,肿瘤侵及邻近肠攀,行膀胱部分切除术和受累小肠及腹直肌切除,显微镜检查在水肿性粘液样基质中可见梭形细胞,胞浆嗜酸性,核仁明显,基质中散布炎症细胞。例2,男,27岁,偶而耻骨弓上痛伴肉眼血尿5-7个月入院,输血2单位,CT增强在膀胱前壁发 Bladder inflammatory pseudosarcoma (pseudotumor) is a rare disease, is a benign disease, radiology and cystoscopy with malignant mesodermal bladder tumor can not be distinguished only in the pathological examination before a clear diagnosis. The authors report two articles and review the literature describing their CT and clinical and pathological findings. To the best of the author’s knowledge, there have been nine reports in the British Oncology, Pathology and Urology literature, but no radiology literature has been reported. Case 1, female, 55 years old, intermittent pubic bowel pain and frequent urination 2 months admission, microscopic hematuria, urinary tract infection with antibiotics, physical examination showed no abnormalities, CT enhanced in the anterior bladder wall found 7-8cm Enhanced necrotizing mass, tumor invasion and the surrounding tissues and adjacent rectus abdominis, the general pathological examination confirmed the CT seen, in addition, the tumor invaded the adjacent intestinal climb, partial bladder resection and involvement of the small intestine and rectus abdominis resection Microscopically, spindle cells were observed in the edematous mucoid matrix with cytoplasm eosinophilic and obvious nucleoli. Inflammatory cells were scattered in the matrix. Example 2, male, 27 years old, occasional suprapubic pain with gross hematuria 5-7 months admission, transfusion of 2 units, CT enhancement in the anterior bladder wall hair
