We report a case of advanced gallbladder cancer in a 58-year-old man. On ultrasonography, there were anechoic foci within the tumor. Although anechoic foci within a thickened gallbladder wall usually represent intramural diverticula (dilated Rokitansky-Aschoff sinuses) of adenomyomatosis, cystically dilated cancerous glands were the etiology of these foci in this case. Thus, gallbladder cancer may also have anechoic foci within the tumor.
我们报告一例58岁男性的晚期胆囊癌病例。超声检查显示肿瘤内有无回声灶。虽然胆囊壁增厚内的无回声灶通常代表腺肌增生症的壁内憩室（扩张的罗-阿窦），但在本例中，这些病灶的病因是囊状扩张的癌性腺管。因此，胆囊癌肿瘤内也可能出现无回声灶。
