Adenomyomatosis :a benign condition described as hyperplastic changes of unknown cause involving the wall of gallbladder and causing overgrowth of the mucosa, thickening of the muscular wall, and formation of intramural diverticula or sinus tracts termed Rokitansky-Aschoff sinuses .
Adenomyomatosis is a common tumorlike lesion of the gallbladder with no malignant potential and may involve the gallbladder in a focal, segmental, or diffuse form.
This patient underwent routine sonography of the abdomen. Ultrasound images of the gall bladder reveal thickening and constriction of the mid segment dividing the lumen into a fundic area and another part towards the neck. There is also evidence of small calculi in the fundic segment of the gall bladder.
These ultrasound images suggest segmental adenomyomatosis of the gall bladder. Adenomyomatosis of the gall bladder may be segmental, diffuse or fundal. Images taken using Toshiba Powervision ultrasound and color doppler machine.
