CT diagnosis of the giant cystic lesions in abdomen

Objective:To study CT diagnosis and differential diagnosis of the giant cystic lesions in abdomen.Methods:30 cases of the giant cystic lesions were confirmed by surgery and histopathology.The center of the lesion,attenuation,thickness of cystic wall and septa,calcification,fluid fluid level sign and contrast enhancement were analyzed.Results:14 cases of giant cystic lesions in the central lower part of abdomen include 4 cases of ovarian serous cystadenoma,3 ovarian mucinous cystadenoma,1 ovarian simple cystic,1 tubo ovarian inflammatory cyst,1 giant bladder diverticulum and 4 cystic teratoma.13 cases of cystic mass in the central upper part include 5 cases of cystic lymphangioma,2 intestinal duplication,1 giant cystic schwannoma in omental bursa,3 common bile duct cyst and 2 peritoneal pseudocyst.3 cases of retroperitoneal mass included 1 pancreatic pseudocyst and 2 giant hydronephrosis.Conclusion:Most of the giant cystic lesions in abdomen are benign.Overian cystadenoma is the most common.Cystic lymphangioma,retroperitoneal cystic mass and others should also be considered in differential diagnosis.
