摘要
目的 探讨阑尾黏液性肿瘤的CT表现,以提高对该病的诊断认识.方法 回顾性分析经病理检查证实的24例阑尾黏液性肿瘤的CT表现,并对其病理基础进行分析.结果 11例黏液性囊腺瘤表现为管状或类圆形囊性肿块,囊壁可有弧形钙化,囊壁光滑且强化均匀,多伴阑尾炎,少数可合并阑尾套叠入盲肠.12例低级别黏液性肿瘤多表现为长管状或类圆形囊性肿块,瘤灶可部分延伸入盆腔,部分可疝入右侧腹股沟区,囊内可有菲薄分隔,囊壁厚薄不均,可有壁结节、蛋壳样钙化,囊壁、壁结节强化均匀;少数伴阑尾炎或低级别腹膜假性黏液瘤.1例黏液腺癌,CT表现与低级别黏液性肿瘤难以鉴别.结论 阑尾黏液性肿瘤CT表现有一定特征性,确诊需依靠病理检查,术前CT检查对其诊断及手术方式有重要意义.
Objective To investigate CT performance of appendiceal mucinous neoplasm and improve the diagnosis of this disease.Methods The CT performance of 24 patients with pathology proved appendiceal mucinous neoplasm were analyzed retrospectively,and were correlated with the result of pathology to analyze the pathological basis.Results 11 cases of mucinous cystadenoma presented as tubular or round-like cystic mass.The cyst wall might contain arc calcification,smooth and homogeneously enhance after administration of contrast medium.Most cases were accompanied by appendicitis while a few cases occurred with intussusception of appendix into the cecum.12 cases of low-grade appendiceal mucinous neoplasms mostly presented as long-tubular or round-like cystic mass,and part of them extended into the pelvic cavity or herniated into the right inguinal region.The cyst had thin septum and uniform-thickness wall,the latter had mural nodules or egg-shell calcification.Homogeneously enhancement was found in the cyst wall or mural nodules after administration of contrast medium.A few cases were accompanied by appendicitis or low-grade peritoneal pseudo mucinous tumor.One case was mucinous adenocarcinoma,and it was hard to distinguish it from low-grade appendiceal mucinous neoplasm on CT performance.Conclusion The CT performance of appendiceal mucinous neoplasm has certain characteristics,and the diagnosis relies on pathology.Pre-operation CT exam is of important significance for diagnosis and operation methods.
