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.
