Abstract:
ObjectiveTo retrospectively analyze the abdominal computer tomography (CT)findings and pathological results of chronic intestinal schistosomiasis in order to improve the diagnostic accuracy of the disease.MethodsThe plain plus enhanced CT scanning was performed in 56 cases (male 37,female 19; mean age 69.2 years).All cases confirmed by pathological examination.The location,shape,size,calcification and pattern of enhancement of lesion were analyzed by two radiological physicians independently.ResultsThe colon wall of all 56 cases was presented with thickening (0.3-1.2 cm) by CT scanning,among which,43 (76.8％) were presented with welldistributed thickening.The calcification of colon wall included linear calcification (n=42),tram-like calcification (n=19) and spot calcification (n=8).The margin of calcification was clear.The locations of calcification in colon were as follows:whole colon (n =5 ),ascending colon (n =9 ),transverse colon (n=12),descending colon (n =24),rectosigmoid (n=34) and rectum (n=30).There were 17 cases presented with severe calcification.The pathological examinations confirmed that linear and tram-like calcification resulted from calcified ova deposited in submucous,subserosa. In 8 cases with spot calcification and 17 with severe calcification,there were calcified ova deposited in all layers of colon wall,accompanied by chronic inflammation,polyp and schistosomiasis granuloma.There were 5 cases complicated by adenocarcinoma.ConclusionsCT scanning is an important imaging method in the diagnosis of chronic intestinal schistosomiasis,with the distinguishing presentation of well-distributed thickening and calcification in the colon wall.When irregular thickening,mass or nodular are found in the colon wall of patients with chronic intestinal schistosomiasis,colorectal carcinoma should be highly suspected.
