Nine patients with calcification of the gallbladder wall (porcelain gallbladder) were analyzed by ultrasound and the appearance correlated with the CT, radiographic, clinical, and surgical findings. Three distinct patterns were identified: (a) a hyperechoic semilunar structure with acoustic shadowing posteriorly, simulating a stone-filled gallbladder devoid of bile, which was seen in 5 patients; (b) a biconvex , curvilinear echogenic structure with variable acoustic shadowing, seen in all 3 patients with carcinoma of the gallbladder; and (c) an irregular clump of echoes with posterior acoustic shadowing, seen in 1 patient. Potential pitfalls in the diagnosis of gallbladder calcification are presented, and the association between calcification and cancer is emphasized.
对9例胆囊壁钙化（瓷胆囊）患者进行了超声分析，并将其表现与CT、放射学、临床及手术结果进行了对比。识别出三种不同的模式：（a）一种半月形高回声结构，后方伴有声影，类似充满结石而无胆汁的胆囊，5例患者出现此情况；（b）一种双凸曲线状回声结构，伴有可变声影，见于所有3例胆囊癌患者；（c）一种不规则回声团块，后方伴有声影，1例患者出现此情况。文中介绍了胆囊钙化诊断中的潜在陷阱，并强调了钙化与癌症之间的关联。
