Angiography in Malignant and Chronic Inflammatory Lesions of the Gallbladder

Angiography findings in 18 patients with carcinoma of the gallbladder and 17 with cholecystitis indicate that similar abnormalities may appear in both lesions. Irregularities and obstruction of arteries were more common in malignant disease and somewhat more severe. Accumulation of contrast medium and prominent veins occurred in both groups. Displacement of adjacent vessels was more common in malignant disease. As chronic inflammatory lesions cannot with certainty be differentiated angiographically from malignant disease, cholecystectomy is recommended when the abnormalities described are demonstrated.
