Abstract:
Objective To explore the CT characteristics of mucinous cystadenocarcinoma of appendix.Methods The CT findings of 5 patients with mucinous cystadenocarcinoma of appendix proved by surgery and pathology were analyzed retrospectively,and the corresponding literatures were also reviewed.Results All lesions in 5 patients showed cystic changes in the right hypogastrium inclu-ding irregular shape with lobulation in 4 and tubular shape in 1.The maximum traverse diameters ranged from 27 mm to 146 mm. Unclear boundary was showed if the lesion invaded the adjacent gut.The cystic wall was asymmetry and thickened with little nodes and nipple in the inner wall.The thick septa were seen in 3 tumors.Much mucus was seen in tumors with uneven density and average CT value of 1 9.3 HU-34.6 HU.On enhanced CT,obvious enhancement of the cystic wall and septa in 4 and moderate enhance-ment in 1 was showed.The adjacent fatty gap of 3 tumors were clear,however it was vague when accompanied with acute inflamma-tion.Small calcification in 3 and enlarged lymphatic nodes in 3 were also found.Conclusion CT shows some characteristics of mu-cinous cystadenocarcinoma of appendix and plays an important role in the diagnosis of the disease.
