[Ulrasound diagnosis of melanoma metastasis into the gallbladder]

A clinico-ultrasound description of presentation of melanoma metastases to the gallbladder in 8 patients is discussed. Secondary lesions to the bladder presented as exophytic outgrowths extending from the bladder wall into the lumen. Echo generated by the lesions was of medium intensity and low intensity around the edge of the elastic wall. They revealed dopplergaphic signs of blood flow. Complex application of echo- and dopplergraphy offered a means of differential diagnosis of metastatic lesions and other pathologies of the gallbladder presenting as exophytic outgrowths in the bladder wall in melanoma patients.
