Abstract

A ciliated foregut cyst arising from the gall bladder is very rare with only a few reports to date. In our case, an ultrasonogram (US) showed a well-demarcated hypoechoic mass containing internal hyperechoic material in the fundus of the gallbladder. The CT scans showed a poorly enhancing round soft tissue mass in the gallbladder wall lined by an enhancing intact mucosal layer. We report here on a very rare form of the ciliated foregut cyst arising from the gall bladder including ultrasound and CT image results.

• 

  Fig. 1 An abdominal ultrasonogram shows a well-circumscribed hypoechoic mass (white arrow) with hyperechoic content in the fundus of the gallbladder.

• 

  Fig. 2 A, B. The non-enhanced (A) and contrast-enhanced CT (B) scans show a well defined round mass (white arrow) with high attenuation. (Hounsfield unit: ranging from 40 to 48). The mass did not however show enhancement.

• 

  Fig. 3 An endoscopic ultrasonogram shows a well-defined hypoechoic cystic mass (white arrow) in the wall of the gallbladder.

• 

  Fig. 4 A. The lower right corner shows the lumen of the gallbladder (arrowhead). The cyst (arrow) is located in the serosal area (H & E; ×12.5). B. A photomicrography shows the cyst lined with ciliated, pseudostratified columnar epithelium (H & E; ×200). Underlying smooth muscle layer that is reactive with smooth muscle actin (SMA) is visualized in the small photomicrography of left lower corner (SMA; ×200).
