摘要

目的：探讨阑尾黏液性囊腺瘤的MDCT表现及其相关病理基础，评价MDCT对其诊断和鉴别诊断价值。方法：回顾性分析13例经手术病理证实的阑尾黏液性囊腺瘤的CT及临床资料。结果：13例均表现右下腹回盲部囊性肿块，CT轴位扫描结合MPR提示肿瘤符合阑尾走向，呈管状或类圆形。肿瘤界限多较清晰，最大横径平均4.2 cm。囊壁多较薄而均匀，厚度平均0.3 cm，内壁多较光整，9例见囊壁钙化。囊内密度较均匀，CT值平均25.7 HU，9例见纤细条状分隔。动态增强检查，囊壁多呈乏血供改变。周边少量积液者2例，网膜包裹l例，l例合并肠系膜淋巴结肿大。结论：MDCT对阑尾黏液性囊腺瘤的诊断及鉴别有较大价值。

Abstract

Objective: To explore the manifestations of MDCT in mucinous cystadenoma of appendix and correlated with pathology, and evaluate the value of MDCT in the diagnosis and differential diagnosis. Methods: MDCT findings and clinical data of 13 mucinous cystadenomas of appendix proved by surgery and pathology were analyzed retrospectively. Results: All 13 cases showed mass in right hypogastrium near cecum. The images of axial section and MPR showed the tumors were oval or tubular in accordance with the path of appendix. Most tumors showed clear boundary and the mean diameter was 4.2 cm. The cystic wall of most tumors were thin, smooth and symmetrical, the mean thickness was 0.3 cm, the inner wall of most tumors were smooth, in 9 cases calcification can be seen in the cystic wall. The density of inner composition of tumors were symmetrical and the mean CT value was 25.7 HU, slim septae can be seen in 9 cases. On DCE-CT, most tumors showed mild continuous enhancement. Local ascites near tumor can be seen in 2 cases, local omentum major packed around in 1 case and enlarged lymph nodes occured in 1 case. Conclusion: MDCT has important value in the diagnosis and identification for mucinous cystadenoma of appendix.
