Spread of gallbladder carcinoma: CT evaluation with pathologic correlation

Background: To assess the accuracy of computed tomographic (CT) imaging in the detection of spread and staging of gallbladder carcinoma. Methods: CT findings of spread of gallbladder carcinoma in 59 Japanese patients who underwent radical surgery were correlated retrospectively with pathologic findings. Results: The incidence of histologically proven nodal involvement was 54% (32 patients) and the most common spread of gallbladder carcinoma. The sensitivities in CT detection of N1 and N2 nodal involvement were 36% and 47%, respectively; positive predictive values were 94% and 92%, respectively. Direct extension to the liver, extrahepatic bile duct, and gastrointestinal tract or pancreas were histologically confirmed in 24, 18, and five patients. The sensitivities in the CT detection of direct spread to the liver of less than 2 cm, more than 2 cm, the extrahepatic bile duct, and the gastrointestinal tract or pancreas were 65%, 100%, 50%, and 57%, respectively; positive predictive values were 77%, 100%, 90%, and 100%, respectively. The incidence of liver metastases and involvement of interaortocaval nodes were 7% and 16%, respectively. The sensitivities in CT detection of liver metastases and involvement of interaortocaval nodes were 75% and 21%, respectively; positive predictive values were 100% and 86%, respectively. CT could not detect direct spread to omentum and peritoneal seedings. Conclusion: For detecting the spread of gallbladder carcinoma, CT imaging has low to moderate sensitivity; however, CT imaging can help in determining resectability and in planning the treatment, especially in advanced-stage gallbladder carcinoma, because of a high positive predictive value.

Carcinoma of the gallbladder: CT findings in 50 cases

Fifty patients with histologically proven carcinoma of the gallbladder were examined by computed tomography (CT). The gallbladder masses were categorized into two broad groups: group 1 (74%) included patients in whom the gallbladder was identified along with a mass lesion; and group 2 (26%), where a large mass was present in the gallbladder fossa with no identifiable gallbladder. Group 1 was further divided into three types according to the nature of the tumor: Type 1, mass almost filling the entire gallbladder lumen; Type 2, a polypoidal mass projecting into the lumen; type 3, an infiltrating tumor seen as focal or diffuse wall thickening. Liver involvement, in the form of localized invasion in the vicinity of the primary gallbladder malignancy, was the most common associated finding (80%). Other ancillary features included presence of calculi, lymphadenopathy, and biliary obstruction. CT was found useful for characterizing and defining the extent of carcinoma of the gallbladder. However, it may not consistently demonstrate involvement of the gastrointestinal tract, omentum, and abdominal wall. CT can also be used for aspiration/biopsy guidance of the gallbladder mass in selected cases.
