Imaging spectrum of morphology of carcinoma gall bladder on MDCT

Abstract

Background: In computed tomography (CT) a normal GB wall appears as a thin rim of soft tissue density that enhances post contrast. A thickened GB wall measures > 3mm.Few cases of GB carcinoma are identified incidentally on postoperative histopathology done for causes like cholelithiasis, cholecystitis etc. USG has high sensitivity in detecting advanced lesions while CT is used for detection of early malignant lesions and staging purposes. Aims and objectives: To characterize the various radiological appearances of carcinoma of the Gall bladderon MDCT imaging.Methodology: After Ethical approval MDCT findings from 30 cases of Cytologically proven cases of carcinoma GB were studied retrospectively in the Department of Radiology, Rajendra Institute of Medical sciences, Ranchi from April 2019 to October 2020. Manner of presentation and IHBR dilatation, Locoregional lymphadenopathy or infiltration, distant metastases etc were evaluated. Data was entered into excel sheet and analysed using SPSS from IBM.Results: Females constituted the majority (56.66%) (n=17). Male: female ratio being .07:1. Three types of presentations of GB carcinoma (wall thickening, mass replacing GB and intraluminal mass) were observed in the study on CT. These cases were histopathologically proven as GB carcinoma.CONCLUSION: Understanding the various GB carcinoma presentations can help optimize Noninvasive staging and treatment planning.
