Usefulness of contrast enhanced ultrasonography in imaging of melanoma's gallbladder metastastasis: three cases report

Ultrasound is regarded as the imaging modality of choice for suspected gallbladder pathology. However the specificity of plain ultrsonography (US) is certainly decreased when imaging malignant affections of gallbladder. Contrast enhanced ultrasonography (CEUS) could become an interesting complementary diagnostic tool for differentiating malignant from benign disease. Our purpose is to illustrate the role of CEUS in assessing the diagnosis of gallbladder metastasis from melanoma throughout three cases of patients. Three patients were addressed for US examination because of indeterminate gallbladder hypo densities…
