一名正在接受腹膜透析治疗的52岁终末期肾脏病女性患者有1个月的血性透析液病史。患者在过去12年中有3次细菌性腹膜炎发作。体格检查和实验室检查无明显异常。进行了腹部计算机断层扫描。最有可能的诊断是什么?
A. Calciphylaxis 钙化防御
B. Encapsulating peritoneal sclerosis 包裹性腹膜硬化
C. Fungal peritonitis 真菌性腹膜炎
D. Peritoneal carcinomatosis 腹膜癌扩散
E. Tuberculous peritonitis 结核性腹膜炎
答案解析：
腹部CT示沿腹膜脏壁广泛钙化。腹腔镜探查显示腹膜壁层明显增厚，覆盖有粉笔样沉积物。组织病理学检查显示腹膜壁层纤维化和钙化，符合包膜性腹膜硬化伴广泛钙化。患者拔除腹膜导管并开始维持性血液透析。
