The ultrasonographic finding of small bowel polyps is reported in a 16-year-old girl, referred for evaluation of abdominal pain. The sonographic study was of particular value in also excluding pregnancy and in documenting small bowel obstruction. We have found that distended small bowel and its contents are accessible to sonographic evaluation, in this case, the constellation of clinical and sonographic findings were of considerable value in diagnosing Peutz-Jeghers syndrome.

Inflammation of the wall of the gallbladder causes a loss of the integrity of its muscular layers. When this occurs there is an evagination of the mucosal lining of the gallbladder wall forming the so-called Rokitansky-Aschoff sinuses that extended to the muscular layer and often to the serosa of the gallbladder wall. These sinuses do communicate with the lumen of the gallbladder. Luschkas ducts or crypts are similar structures, with a mucosal lining; however, they do not communicate with the gallbladder lumen, but rather are attached to the inner surface of the gallbladder by a fibrous cord. This cord most likely represents the obliterated opening of the Rokitansky-Aschoff sinus due to inflammation of the wall of the gallbladder. Diverticulae of the gallbladder appear to originate in a similar manner and are not found in the normal gallbladder
