A 75 year woman developed a primary malignant melanoma of the gallbladder. The patient presented with abdominal pain in the upper right quadrant typically seen in acute cholecystitis. Neither intravesical concretions nor cholestasis was seen. Ultrasound demonstrated hyperechogenic intraluminal "school of fish" reflections, which are typical for metastatic melanoma to the gallbladder. Intravesical fluid collection was not present. The tumor did not expand past the wall of the gallbladder. The main sonographic features are hyperdense intraluminal strands of tumor and the lack of fluid. Computed tomography showed solid intraluminal masses with hypodensive and partially hyperdensive reticular structure.
一名75岁女性患原发性胆囊恶性黑色素瘤。患者表现为右上腹腹痛，这在急性胆囊炎中较为常见。未发现膀胱内结石或胆汁淤积。超声显示腔内高回声“鱼群”样反射，这是胆囊转移性黑色素瘤的典型表现。膀胱内无积液。肿瘤未超出胆囊壁。主要超声特征是腔内高密度肿瘤条索且无积液。计算机断层扫描显示腔内实性肿块，具有低密度和部分高密度的网状结构。
