title: Sonographic diagnosis of primary carcinoma of the gallbladder. Summary of one year's examinations.
abstract: The material of 1 year's sonographic examinations of the gallbladder region have been analyzed for diagnosis of gallbladder carcinoma in a prospective study from a large hospital. Of 11 cases diagnosed sonographically 6 were proved corrected by surgery or autopsy; 5 were false-positive results. In addition, there was 1 false-negative diagnosis. In 3 sonographically diagnosed cases fine-needle aspiration biopsy of suspected liver infiltration gave 2 positive and 1 false-positive result. Sonography can suggest the diagnosis of gallbladder carcinoma, but inflammatory changes in the gallbladder may simulate or mask the signs of malignancy.
