ABSTRACT
Background: Carcinoma gallbladder is a major problem in India. In this retrospective study from the tertiary care centre of the north–east India, we aim to review the various Multidetector Computed Tomography (MDCT) imaging findings of gallbladder carcinoma. Methods: We retrospectively analysed MDCT findings in 65 biopsy proven cases of gallbladder carcinoma. After administration of oral contrast for bowel opacification, all patients were subjected to non–contrast scan of the upper abdomen followed by contrast enhanced study of the abdomen and pelvis in the portal venous phase. Results: Focal mass lesion arising from gallbladder was the predominant pattern of growth seen in 31(48%) patients followed by focal or asymmetric diffuse wall thickening in 28(43%) patients. Twelve (18%) patients had mass in gallbladder fossa replacing the gall bladder. Adjacent hepatic infiltration was seen in 48(74%) patients. Conclusion: Our study highlights the importance of MDCT for the diagnosis, characterisation and staging of gallbladder carcinoma.
