The abdominal ultrasound examinations of 464 patients with malignant melanoma performed over a 3 year period were reviewed. 23 (5.2%) had soft tissue material attached to the gallbladder wall and projecting into the lumen. Four of these were polyps of less than 1 cm which were thought to be benign, while the remaining 19 had abnormalities likely to be metastatic melanoma. Upper abdominal ultrasound examinations are frequently requested for staging purposes in patients with thick high grade malignant melanoma or clinical suspicion of metastases. Ultrasound clearly identifies the gallbladder and biliary tree in the vast majority of patients and is generally regarded as the imaging modality of choice for suspected gallbladder pathology. As autopsy studies have confirmed the incidence of gallbladder metastases from malignant melanoma to be 15-20%, a careful review of the gallbladder is advocated when abdominal ultrasound examinations are performed on patients with malignant melanoma.
回顾了464例恶性黑色素瘤患者在3年期间进行的腹部超声检查。23例（5.2%）有软组织附着于胆囊壁并突入腔隙。其中4例为小于1cm的息肉，被认为是良性的，而其余19例有异常，可能是转移性黑色素瘤。对于厚的高级别恶性黑色素瘤患者或临床怀疑有转移的患者，经常要求进行上腹部超声检查以进行分期。超声在绝大多数患者中能清晰识别胆囊和胆管树，通常被视为疑似胆囊病变的首选成像方式。由于尸检研究已证实恶性黑色素瘤胆囊转移的发生率为15%-20%，因此在对恶性黑色素瘤患者进行腹部超声检查时，提倡仔细检查胆囊。
