gallbladder adenomyomatosis

Leann Kania, Flavius Guglielmo, Donald Mitchell
Few things in radiology are "pathognomonic" in their appearance or presentation. However, having an awareness of those findings which are specific to a certain entity is important when interpreting imaging studies. These classic findings can be identified with many imaging modalities, but no modality provides as many recognizable observations as an MRI. This results from the large variety of pulse sequences that provide high contrast resolution, prior to and following contrast administration. In this article, the most classically recognized abdominal findings are presented including the following: Liver: Cyst, hemangioma, focal nodular hyperplasia, hepatic adenoma, hemosiderosis, hepatocellular carcinoma...

Gallbladder adenomyomatosis (GAM) is an acquired, reactive, tumor-like condition. Malignant transformation is extremely rare, and imaging features during contrast-enhanced ultrasound (CEUS) have not been described before. Herein, we describe a 73-year-old Asian man who had been diagnosed with gallbladder carcinoma by conventional ultrasonography (US). Based on additional radiological findings, we believed that it was a localized adenomyomatosis. However, the histopathological diagnosis was adenocarcinoma originate from adenomyomatosis with serosal invasion...

Fusion images of diffusion-weighted whole-body imaging with background body signal suppression and T2-weighted image (DWIBS/T2) demonstrate a strong signal for malignancies, with a high contrast against the surrounding tissues, and enable anatomical analysis. In the present study, DWIBS/T2 was compared with18 F-fluorodeoxyglucose (18 F-FDG) positron emission tomography/computed tomography (PET/CT) for diagnosing cancer in the abdomen. Patient records, including imaging results of examination conducted between November 2012 and May 2014, were analyzed retrospectively...

Gallbladder (GB) adenomyomatosis (ADM) is a benign, acquired anomaly, characterized by hypertrophy of the mucosal epithelium that invaginates into the interstices of a thickened muscularis forming so-called Rokitansky-Aschoff sinuses. There are three forms of ADM: segmental, fundal and more rarely, diffuse. Etiology and pathogenesis are not well understood but chronic inflammation of the GB is a necessary precursor. Prevalence of ADM in cholecystectomy specimens is estimated between 1% and 9% with a balanced sex ratio; the incidence increases after the age of 50...

Some clinicians have proposed a relationship between gallbladder (GB) cancer and adenomyomatosis (ADM) of the gallbladder, although the latter condition is not considered to have malignant potential. We retrospectively reviewed the surgical pathology database of patients who underwent resection for ADM of the gallbladder at our institution from March 2005 to May 2015. In total, 624 patients underwent surgical resection of the gallbladder with Rokitansky-Aschoff sinuses. Of these cases, 93 were pathologically diagnosed with ADM of the gallbladder, with 44 (47...

A 74-year-old man underwent regular follow-up observations after being diagnosed with gallbladder adenomyomatosis based on findings, such as the thickening of the wall of the gallbladder fundus and the presence of intramural cysts. Over the course of 3 years, a papillary tumor located on the thickened wall of the gallbladder had increased in size and extended into the lumen. Consequently, the patient was diagnosed with gallbladder cancer and underwent extended cholecystectomy. The histological diagnosis was intracystic papillary neoplasm (ICPN) of the gallbladder...

The aim of this study was to clarify the clinicopathological characteristics of incidental gallbladder cancer(iGBC)diagnosed after laparoscopic cholecystectomy. A total of 33 patients diagnosed with iGBC were enrolled in this study, and their clinicopathological characteristics were investigated. Preoperative diagnoses were as follows: cholelithiasis in 16 patients, polypoid lesions in 8, cholecystitis in 7, and adenomyomatosis in 2. Depth of mural invasion of iGBC was M in 14 cases, MP in 3, SS in 12, and deeper than SS in 4...

Gallbladder adenomyomatosis (GA) is a benign alteration of the gallbladder wall that can be found in up to 9% of patients. GA is characterized by a gallbladder wall thickening containing small bile-filled cystic spaces (i.e., the Rokitansky-Aschoff sinuses, RAS). The bile contained in RAS may undergo a progressive concentration process leading to crystal precipitation and calcification development. A correct characterization of GA is fundamental in order to avoid unnecessary cholecystectomies. Ultrasound (US) is the imaging modality of choice for diagnosing GA; the use of high-frequency probes and a precise focal depth adjustment enable correct identification and characterization of GA in the majority of cases...

INTRODUCTION: An important issue in laparoscopic surgery is initial peritoneal access. An intraumbilical (IU) incision may be easier and faster to place, but due to concerns about wound complications, the periumbilical (PU) incision is still often used. A prospective randomized controlled study was performed to investigate the outcomes of the IU incision and PU incision in laparoscopic cholecystectomy. METHODS: Study subjects were patients who received laparoscopic cholecystectomy for acute or chronic cholecystitis, gallbladder polyp or adenomyomatosis, or porcelain gallbladder from June 2014 to January 2015...

BACKGROUND: Gallstones are detected in about 5% of healthy Japanese. We followed up individuals showing gallstones upon screening, investigating features of those requiring surgery. METHODS: In 2002 we performed health evaluations for 21,550 persons (13,986 men and 7,564 women), detecting gallstones ultrasonographically in 837 or 3.9% (561 men, or 4.0%; 276 women, or 3.6%). Up until 2012, we followed up 720 of the 837 persons with gallstones (86.0%) and compared individuals requiring or not requiring cholecystectomy as to age, gender, body mass index, diabetes, liver function, lifestyle, abdominal symptoms, and ultrasonographic findings...

Adenomyomatosis of the gallbladder (ADMG) is characterized by proliferation of the mucosal epithelium and hypertrophy of the muscularis. ADMG is predominantly diagnosed by using ultrasonography. Although ADMG is benign in nature, lithiasis, and chronic inflammation secondary to it may lead to dysplastic changes and cancer. Mucosal invagination through the hypertrophied muscularis results in large intramural diverticula or sinus tracts which are visible at radiology, known as Rokitansky-Aschoff sinuses. Histologically, ADMG manifests with hyperplasia of the muscular layer and proliferation of mucosal glandular tissues...

AIM: To investigate the diagnostic and therapeutic assessment in children with adenomyomatosis of the gallbladder (AMG). METHODS: AMG is a degenerative disease characterized by a proliferation of the mucosal epithelium which deeply invaginates and extends into the thickened muscular layer of the gallbladder, causing intramural diverticula. Although AMG is found in up to 5% of cholecystectomy specimens in adult populations, this condition in childhood is extremely uncommon...

Differentiation between adenomyomatosis (ADM) and cancer of the gallbladder is necessary during diagnosis. Diffusion-weighted whole body imaging with background body signal suppression (DWIBS) images are able to indicate cancer and inflammation. The fusion of a DWIBS with a T2 weighted image (DWIBS/T2) facilitates both functional and anatomical investigations. In the present study, patient records and images from patients with surgically confirmed ADM from April 2012 to October 2014 were analyzed retrospectively...

With its excellent contrast and spatial resolution, and the ability to image in real-time, ultrasound is the main imaging modality for assessing the gallbladder (GB). The application of contrast-enhanced ultrasound (CEUS) of the GB is now increasingly recognized as a useful addition to ultrasound and other cross-sectional imaging in the assessment of neoplastic and non-neoplastic GB disease. With the ability to image microcirculation and optimal contrast resolution, CEUS allows high-quality delineation in real-time, allowing for increased diagnostic confidence...

An analysis of premalignant lesions, risk factors and models of carcinogenesis of gallbladder cancer (GBC) involves the concept of organ specificity. In GBC, the dysplasia-carcinoma sequence and metaplasia-dysplasia-carcinoma sequence are considered to be more important models of carcinogenesis than the adenoma-carcinoma sequence. Cholecystectomy is recommended for gallbladder polyps ≥1.0 cm, and all pre-invasive adenomas and papillary neoplasms ≥1.0 cm are defined as intracholecystic papillary-tubular neoplasms (ICPTNs)...

BACKGROUND: Gallbladder adenomyomatosis (GA) is a benign gallbladder entity discovered as an asymptomatic gallbladder mass. Since gallbladder cancer is in the differential diagnosis for gallbladder masses, the ability to differentiate benign disease avoids a more extensive oncologic resection. This study sought to review imaging modalities used to diagnose GA. METHODS: PubMed and SciVerse Scopus were systematically searched using the terms: "gallbladder adenomyomatosis" and "gallbladder imaging" for articles published between January 2000 and January 2015...
