Gallbladder cancer with intratumoral anechoic foci: a mimic of adenomyomatosis.
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.
