The fundal type gallbladder adenomyomatosis can be treated by partial laparoscopic cholecystectomy. As for asymptomatic gallbladder adenomyomatosis, a conservative treatment is recommended with ultrasound exams twice a year. Diffuse gallbladder adenomyomatosis is characterized by the involvement of the whole organ that consequently appears contracted, even after fasting.Īt present, the main treatment for gallbladder adenomyomatosis is surgery, but it is very important to screen patients and make clear the operation indications, taking the complications after cholecystectomy into consideration.According to some authors, annular gallbladder adenomyomatosis should be considered a subtype of segmental gallbladder adenomyomatosis 8. As a consequence, biliary sludge and stones may accumulate into the isolated fundal compartment 7. In some cases, epithelial proliferation may be particularly conspicuous and subdivide the gallbladder lumen into two separate compartments. The gallbladder appears contracted only in the involved portion, changing its global morphology and becoming “hourglass-shaped”. Annular gallbladder adenomyomatosis is characterized by a ring-form thickening of the gallbladder wall, usually involving the middle portion.The involved portion appears contracted, whereas the uninvolved one maintains its normal shape. Segmental gallbladder adenomyomatosis is characterized by the involvement of a larger portion of the gallbladder wall, typically the fundus and the distal third of the body.The uninvolved gallbladder wall appears physiologically thin and the overall gallbladder shape is usually maintained. Localized gallbladder adenomyomatosis is the most common pattern and is characterized by a focal thickening, usually involving the fundal region (the so-called “fundal gallbladder adenomyomatosis”).Gallbladder adenomyomatosis has four morphological types according to the localization in the gallbladder wall (see Figure 1) 6: 1) Fundal (localized) type, 2) segmental type, 3) diffuse type and 4) annular type 6. Other authors state that the prevalence is similar in men and women. Specifically, some authors state that adenomyomatosis is more prevalent in women than men (3:1). There are discrepancies in the literature regarding the prevalence of adenomyomatosis in males and females. Although there is a wide age range of patients who are diagnosed with adenomyomatosis, patients are most frequently diagnosed in their 50s 3. In cases where it is difficult to distinguish adenomyomatosis from gallbladder cancer or when adenomyomatosis is associated with right upper quadrant pain, this condition may be treated with a cholecystectomy 4.Īdenomyomatosis has been found in 1% to 8.7% of cholecystectomy specimens 3. Adenomyomatosis also can be associated with right upper quadrant pain. Adenomyomatosis is often asymptomatic and incidentally detected, requiring no specific treatment 3. Sometimes, particularly when the characteristic imaging findings are not present, adenomyomatosis can be difficult to distinguish from gallbladder cancer based on the diagnostic imaging findings. The gallbladder wall thickening, Rokitansky-Aschoff sinuses, and the calculi and/or cholesterol crystals that are often found in sinuses characterize the imaging appearance of adenomyomatosis 3. Rokitansky-Aschoff sinuses may contain calculi and/or cholesterol crystals. Gallbladder adenomyomatosis also known as adenomyoma or adenomyomatous hyperplasia of the gallbladder, is a benign (non-cancerous) condition characterized by epithelial proliferation and hypertrophy of the muscles of the gallbladder wall 1 with an outpouching of the mucosa into or through the thickened muscular layer, i.e., the Rokitansky-Aschoff sinuses 2.
