We present computed tomographic (CT) and sonographic findings of heterotopi
c gastric mucosa incidentally found in a 63-year-old male. CT showed a slig
htly high density area in the gallbladder, which was intermediately enhance
d early after bolus injection of contrast medium. Ultrasonography showed an
echogenic sessile polyp. Histologically, the tumor consisted of gastric fu
ndic glands containing parietal cells and chief cells.
