The authors analyze the clinical, radiological, and ultrasonography findings in a personal series of 3 cases, and 6 other cases reported in the published literature. As a result of their studies, they propose several groupings of symptoms and signs which enabled a precise diagnosis to be made in 5 cases.

Primary cancer of gallbladder was detected by ultrasonography in 16 patients (10 women, 6 men), and confirmed at operation. Two main types of lesion were found: 8 localized forms (infiltrating or vegetating), and 8 diffuse forms with infiltration of the gallbladder wall. The lesion was an adenocarcinoma in each case, and there was associated lithiasis in 11 patients. Extension by contiguity or metastases is independent of the size of the cancer. Problems related to etiological and differential diagnosis of these lesions are discussed in relation to the different ultrasonography appearances observed.

The authors conducted a retrospective analysis of 28 case-reports of patients with kidney transplants who had been investigated by ultrasonography. The most representative cases in the 8 patients in whom this examination revealed the presence of surgical complications are described. They included three cases of urinoma, in one case with associated obstruction, two patients with lymphoceles, one of whom had obstruction, and one case each of perirenal hematoma, perirenal abscess, and an arteriovenous fistula following needle biopsy.
