Abstract Objective: To study CT features and pathologic characteristics of calcified gastric carcinoma． Method: The CT features of calcified gastric carcinoma in 19 patients were analyzed before operation, also were correlated with pathologic characteristics after operation． Results: The Borrmann’s classification of lesions in the 19 patiens were all Borrmann IV． The pathological types of the lesions in the 19 patiens were gastric mucoid adenocarcinoma, signet ring carcinoma, poorly differentiation adenocarcinoma abundant with mucous． In CT image, diffuse thickening of gastric wall with the belt of lower density in lesion or lower density in all the lesion was observed, while calcified granules were diffusely distributed in the lesion． The CT value was (22.34±3.24)HU, which was statistically singnificant(P<0．05) by t test． The pathological features were that tumour tissue and mesenchyme were abundant with mucous and calcified area scattered within the lesion, the tumor cells infiltrated along the stomach wall． Conclusion: Calcified gastric carcinoma has special CT image and special pathology features． Calcified gastric carcinoma was poorly differentiated, and high malignancy and with poorest prognosis． It was of great significance in diagnosis and treatment of calcified gastric carcinoma．
