| 目的 探讨腹膜假黏液瘤(PMP)的CT表现特点.方法 回顾性分析43例确诊为PMP的患者临床、病理及CT影像资料.结果 PMP较常见的CT表现包括腹腔囊性占位(43/43,100%)、腹膜及网膜增厚、网膜饼(43/43,100%)、密度不均匀的腹腔积液(38/43,88.37%)及肝、脾被膜压迹(36/43,83.72%);较少见的CT表现包括腹腔内钙化灶(18/43,41.86%)、肠梗阻(17/43,39.53%)、心包积液(15/43,34.88%)、腹壁肌肉内囊性肿块(12/43,27.91%)、胸腔积液(11/43,25.58%)、肝脾实质内囊性灶(10/43,23.26%)、输尿管及肾盂积水(10/43,23.26%)、腹腔及心包旁肿大淋巴结(4/43,9.30%)、腹膜后囊性灶(4/43,9.30%)、食管裂孔内囊性灶(3/43,6.98%)及阑尾肿瘤(3/43,6.98%).术后病理诊断为高级别PMP 20例,低级别PMP 23例.结论 PMP临床少见,易误诊,CT表现多样但具有一定的特征性,有助于诊断及鉴别诊断. |

| Objective To investigate CT features of pseudomyxoma peritonei (PMP). Methods The clinical, pathologic data and CT images of 43 patients with PMP were analyzed retrospectively. Results CT performances of PMP commonly included peritoneal cavity cystic masses (43/43, 100%); peritoneal, omental thicking and omental cakes (43/43, 100%); ascites with heterogeneous density (38/43, 88.37%); hepatic and splenic scallopings (36/43, 83.72%). Other uncommon CT performance included calcification in the cystic mucinous masses (18/43, 41.86%), intestinal obstruction (17/43,39.53%), hydropericardium (15/43, 34.88%), cystic mucinous masses in abdominal muscle (12/43, 27.91%), hydrothorax (11/43, 25.58%), cystic mucinous masses in liver and spleen (10/43, 23.26%), ureteral and renal pelvis dilation (10/43, 23.26%), enlarged lymph nodes in abdominal cavity and pericardium (4/43, 9.30%), cystic mucinous masses in retroperitoniu (4/43, 9.30%), cystic mucinous masses in esophageal hiatus (3/43, 6.98%) and appendiceal masses (3/43, 6.98%). There were 20 cases of high-grade PMP and 23 cases of low-grade PMP confirmed by post-operation pathology. Conclusion PMP is an uncommon disease and hard to diagnose. However, there are some characteristic CT findings which is helpful for the diagnosis and differential diagnosis. |
