CT seans of 23 patients with gallbladder carcinoma were retrospectively reviewed to determine the incidence of lymphatic spread and to access the pattern of regional lymph node metastases. The lymphatic spread were noted in 74%(17/23). The involved patterns of regional lymph node metastases were nodes of porta hepatis 65%, portocaval nodes 41%, superior pancreaticoduodenal nodes 47%, posterior pancreaticoduodenal nodes 59%, nodes aroud the celiac trunk 35%, nodes around the superior mesenteric artery 29% and paraaortic nodes 35% The findings suggested that the pattern of regional lumph node metastases in gallbladder carcinoma occurred along the normal lymphatic pathway of the gallbladder.
