Diffuse malignant peritoneal mesothelioma (DMPM) and peritoneal carcinomatosis have similar computed tomography imaging features. Peritoneal carcinomatosis is a known metastatic site for many malignancies and particularly gastrointestinal tract and ovarian cancers. Also, DMPM can masquerade as an ovarian epithelial neoplasm, with very similar clinical presentation and an overlap in imaging findings. When no evident primary tumor is detected other than the peritoneal disease, primary malignant mesothelioma should be considered. Since accurate diagnosis is essential for treatment management, the gold standard in differentiating between these two entities lies in histological analysis. We report a case of DMPM that was initially misdiagnosed as an ovarian cancer, where the biopsy of a peritoneal nodule was able to correct and confirm the diagnosis of DMPM.
弥漫性恶性腹膜间皮瘤（DMPM）与腹膜癌在计算机断层扫描成像特征上相似。腹膜癌是许多恶性肿瘤的已知转移部位，尤其是胃肠道和卵巢癌。此外，DMPM可伪装成卵巢上皮性肿瘤，临床表现非常相似，影像学表现也有重叠。当除腹膜疾病外未检测到明显的原发性肿瘤时，应考虑原发性恶性间皮瘤。由于准确诊断对治疗管理至关重要，区分这两种实体的金标准在于组织学分析。我们报告一例最初被误诊为卵巢癌的DMPM病例，其中对一个腹膜结节进行活检后得以纠正并确诊为DMPM。
