Adenomyomatosis uterus radiology

Adenomyomatosis uterus radiology

Adenomyomatosis is a benign condition characterized by hyperplastic changes of unknown cause involving the wall of the gallbladder. Rokitansky—Aschoff sinuses are pseudodiverticula or pockets in the wall of the gallbladder. They may be microscopic or macroscopic.

Histologicallythey are outpouchings of gallbladder mucosa into the gallbladder muscle layer and subserosal tissue as a result of hyperplasia and herniation of epithelial cells through the fibromuscular layer of the gallbladder wall. Rokitansky—Aschoff sinuses are not of themselves considered abnormal but they can be associated with cholecystitis.

They form as a result of increased pressure in the gallbladder and recurrent damage to the wall of the gallbladder. Black pigment gallstones can form in Rokitansky—Aschoff sinuses of the gallbladder after the fourth to fifth decades of life in absence of the typical risk factors for bilirubin suprasaturation of bile.

Cases of gall bladder cancer have also been reported to arise from Rokitansky—Aschoff sinuses. On abdominal ultrasoundRokitansky—Aschoff sinuses are seen as highly echogenic nodes with "comet tail" reverberation, which represent cholesterol crystals.

Thickened and spongy myometrium.Adenomyomatosis of the gallbladder is a hyperplastic cholecystosis of the gallbladder wall. It is typically seen in patients in their 5 th decade. The incidence increases with age, presumably the result of protracted inflammation see below. It is most often an incidental finding and usually requires no treatment. It may be found more often in chronically inflamed gallbladders which are at higher risk for carcinomabut it is not a premalignant lesion in itself 5.

Adenomyomatosis per se is usually asymptomatic. Adenomyomatosis is one of the hyperplastic cholecystoses. Cholesterol accumulation in adenomyomatosis is intraluminal, as cholesterol crystals precipitate in the bile trapped in Rokitansky-Aschoff sinuses.

MRCP is the technique usually employed for the gallbladder and biliary tree characterization. Imaging features include:. Metabolic characterization with FDG PET has been suggested as a useful adjunct in problematic cases 4but there have also been cases with increased uptake in areas of adenomyomatosis, leading to false positive results 6.

Focal adenomyomatosis may appear as a discrete mass, known as an adenomyoma. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys.

Click here for information on linking to our website or using our content or images.In some instances, your doctor might collect a sample of uterine tissue for testing endometrial biopsy to verify that your abnormal uterine bleeding isn't associated with another serious condition.

But an endometrial biopsy won't help your doctor confirm a diagnosis of adenomyosis. The only way to confirm adenomyosis is to examine the uterus after hysterectomy. However, pelvic imaging such as ultrasound and MRI can detect signs of it. Other uterine diseases can cause signs and symptoms similar to adenomyosis, making adenomyosis difficult to diagnose. Conditions include fibroid tumors leiomyomasuterine cells growing outside the uterus endometriosis and growths in the uterine lining endometrial polyps.

Your doctor might conclude that you have adenomyosis only after ruling out other possible causes for your signs and symptoms. Adenomyosis often goes away after menopause, so treatment might depend on how close you are to that stage of life.
