Objective: To analyze the CT features of mass-type gallbladder carcinoma and to raise awareness of mass-type gallbladder carcinoma. Methods: CT findings of 34 cases of gallbladder carcinoma confirmed by pathology were analyzed retrospectively. Results: CT showed irregular soft tissue mass in the gallbladder, unclear gallbladder wall, unclear boundary between the mass and the liver, enhanced lesion with uneven patchy enhancement, gallbladder calculi and cholecystitis in 11 cases, liver invasion in 21 cases , 5 cases of liver metastasis, 6 cases of adjacent organ invasion, 19 cases of lymph node metastasis, 14 cases of extrahepatic bile duct dilation and 5 cases of ascites. Conclusion: The CT manifestation of mass-type gallbladder carcinoma has certain characteristic. When it infiltrates the liver, it should be differentiated from the gallbladder phase by liver cancer.
