Abstract
Gallbladder (GB) disease is classified into two broad categories: GB wall-thickening and protuberant lesions, which include various lesions, such as adenomyomatosis, cholecystitis, GB polyps, and GB carcinoma. This review summarizes recent advances in the differential diagnosis of GB lesions, focusing primarily on endoscopic ultrasound (EUS) and related technologies. Fundamental B-mode EUS and contrast-enhanced harmonic EUS (CH-EUS) have been reported to be useful for the diagnosis of GB diseases because they can evaluate the thickening of the GB wall and protuberant lesions in detail. We also outline the current status of EUS-guided fine-needle aspiration (EUS-FNA) for GB lesions, as there have been scattered reports on EUS-FNA in recent years. Furthermore, artificial intelligence (AI) technologies, ranging from machine learning to deep learning, have become popular in healthcare for disease diagnosis, drug discovery, drug development, and patient risk identification. In this review, we outline the current status of AI in the diagnosis of GB.

Abstract
Xanthogranulomatous (XG) inflammatory disease is a rare benign disease involving various organs, including the gallbladder, bile duct, pancreas, spleen, stomach, small bowel, colon, appendix, kidney, adrenal gland, urachus, urinary bladder, retroperitoneum, and female genital organs. The imaging features of XG inflammatory disease are nonspecific, usually presenting as a heterogeneous solid or cystic mass. The disease may also extend to adjacent structures. Due to its aggressive nature, it is occasionally misdiagnosed as a malignant neoplasm. Herein, we review the radiological features and clinical manifestations of XG inflammatory diseases in various organs of the abdomen and pelvis.

Xanthogranulomatous cholecystitis in a patient with ulcerative colitis and primary sclerosing cholangitis: A case report. Radiol Case Rep 2023; 18:3513-3521. [PMID: 37547791 PMCID: PMC10403711 DOI: 10.1016/j.radcr.2023.07.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 07/06/2023] [Accepted: 07/10/2023] [Indexed: 08/08/2023] Open
Abstract
Chronic gallbladder disease due to xanthogranulomatous cholecystitis is uncommon, and its symptoms are generally vague. While there is no firm evidence to link xanthogranulomatous cholecystitis to primary sclerosing cholangitis or ulcerative colitis. The patient is a 41-year-old male with a history of ulcerative colitis, primary sclerosing cholangitis, and biliary stenting who complained of symptoms of anorexia, jaundice, and pruritus. In the initial ultrasound exam, there was evidence of intrahepatic and extra-hepatic bile duct dilation along with a significant and mass-like circumferential thickening of the gallbladder wall. Magnetic resonance cholangiopancreatography was performed for further evaluation, which indicated increased gallbladder wall thickness, containing multiple T2 hyper-signal nodules while the mucosal layer was intact. There was also a filling defect in the common bile duct's distal portion. These findings matched a xanthogranulomatous cholecystitis diagnosis and a possibly malignant lesion in the distal of the common bile duct. The patient ultimately had a cholecystectomy, and pathology findings confirmed the diagnosis of xanthogranulomatous cholecystitis. Biopsy specimens obtained from the distal of the common bile duct lesion were microscopically identified as intramucosal adenocarcinoma. In patients with a history of primary sclerosing cholangitis who present with nonspecific symptoms suggesting chronic gallbladder disease and radiologic evidence of circumferential gallbladder wall thickening containing intramural nodules and intact mucosa, xanthogranulomatous cholecystitis should be kept in mind.

Abstract
BACKGROUND The accurate characterization of gallbladder wall thickening (GWT) into benign or malignant on ultrasound (US) is a significant challenge. METHODS We searched the MEDLINE and EMBASE databases for studies reporting two-dimensional grayscale US in benign and malignant GWT. The pooled prevalence was calculated using a generalized linear mixed method with a random-effects model. The pooled sensitivity and specificity were calculated using a bivariate random-effects model. RESULTS Of the 7309 studies screened by titles, 73 studies with 18,008 patients were included. The most common findings in xanthogranulomatous cholecystitis (XGC) were lack of wall disruption and intramural hypoechoic nodules while adenomyomatosis (ADM) was frequently associated with intramural cysts and intramural echogenic foci. Echogenic foci, lack of gallbladder wall disruption, and hypoechoic nodules had a sensitivity of 89%, 77%, and 66% and specificity of 86%, 51%, and 80%, respectively for the diagnosis of benign GWT. Focal thickening and indistinct liver interface had a sensitivity of 75% and 55% and specificity of 64% and 69%, respectively for the diagnosis of malignant GWT. CONCLUSION intramural features (echogenic foci, hypoechoic nodules), gallbladder wall disruption, and liver interface are useful US features for the characterization of GWT.

Abstract
Acute cholecystitis is a common cause of right upper quadrant pain in patients presenting to the emergency department. Ultrasound, computed tomography, HIDA scans, and magnetic resonance imaging are increasingly utilized to evaluate suspected cases. The prognosis of acute cholecystitis is usually excellent with timely diagnosis and management. However, complications associated with cholecystitis pose a considerable challenge to the clinician and radiologist. Complications of acute cholecystitis may result from secondary bacterial infection or mural ischemia secondary to increased intramural pressure. The recognized subtypes of complicated cholecystitis are hemorrhagic, gangrenous, and emphysematous cholecystitis, as well as gallbladder perforation. Acute acalculous cholecystitis is a form of cholecystitis that occurs as a complication of severe illness in the absence of gallstones or without gallstone-related inflammation. Complicated cholecystitis may cause significant morbidity and mortality, and early diagnosis and recognition play a pivotal role in the management and early surgical planning. As appropriate utilization of imaging resources plays an essential role in diagnosis and management, the emergency radiologist should be aware of the spectrum of complications related to cholecystitis and the characteristic imaging features. This article aims to offer a comprehensive contemporary review of clinical and cross-sectional imaging findings of complications associated with cholecystitis. In conclusion, cross-sectional imaging is pivotal in identifying the complications related to cholecystitis. Preoperative detection of this complicated cholecystitis can help the care providers and operating surgeon to be prepared for a potentially more complicated procedure and course of recovery.

How Can We Manage Gallbladder Lesions by Transabdominal Ultrasound? Diagnostics (Basel) 2021; 11:diagnostics11050784.

Abstract
The most important role of ultrasound (US) in the management of gallbladder (GB) lesions is to detect lesions earlier and differentiate them from GB carcinoma (GBC). To avoid overlooking lesions, postural changes and high-frequency transducers with magnified images should be employed. GB lesions are divided into polypoid lesions (GPLs) and wall thickening (GWT). For GPLs, classification into pedunculated and sessile types should be done first. This classification is useful not only for the differential diagnosis but also for the depth diagnosis, as pedunculated carcinomas are confined to the mucosa. Both rapid GB wall blood flow (GWBF) and the irregularity of color signal patterns on Doppler imaging, and heterogeneous enhancement in the venous phase on contrast-enhanced ultrasound (CEUS) suggest GBC. Since GWT occurs in various conditions, subdividing into diffuse and focal forms is important. Unlike diffuse GWT, focal GWT is specific for GB and has a higher incidence of GBC. The discontinuity and irregularity of the innermost hyperechoic layer and irregular or disrupted GB wall layer structure suggest GBC. Rapid GWBF is also useful for the diagnosis of wall-thickened type GBC and pancreaticobiliary maljunction. Detailed B-mode evaluation using high-frequency transducers, combined with Doppler imaging and CEUS, enables a more accurate diagnosis.

Abstract
Introduction: Xanthogranulomatous cholecystitis (XGC) is a rare inflammatory disease of the gallbladder (GB). XGC surgery is a difficult process due to its clinical, radiological, and intraoperative findings. In this study, our aim is to show the difficulties of XGC surgery and to find out if laparoscopic surgery is a sufficient procedure. Materials and Methods: Histological findings of 3339 cholecystectomy patients, who were operated between January 2015 and January 2020, were retrospectively reviewed. Age, gender, radiological results, clinical features, intraoperative findings, and surgical management of the patients with XGC were recorded. Results: XGC was observed in 70 patients (2.09%). The average age was 53.75. M:F ratio was 1.2. In radiological examinations, gallstones were found in 94.2% of the patients and GB wall thickness (≥3 mm) was increased in 58.5% of the patients. Around 45.7% of the patients came to the clinic with chronic cholecystitis and 32.9% with acute cholecystitis. In the intraoperative period, adhesions were observed in 80% and increase in GB wall thickness was observed in 77.1% of the patients. The operation started laparoscopically in 66 patients. In 14 patients (21.2%), it was converted to open surgery usually due to insufficient dissection of Calot's triangle. Gallbladder carcinoma (GBC) was suspected in 6 patients, but none of them had malignancy in frozen sections or histology. Conclusions: XGC surgery is difficult due to its radiological, clinical, and intraoperative features and mimicking GBC. It can be converted to open cholecystectomy due to difficulties in laparoscopic dissection. However, since conversion cholecystectomy rates are reasonable, laparoscopic surgery is recommended in patients with suspected XGC.

Abstract
Diseases associated with gallbladder wall thickening include benign entities such as adenomyomatosis of the gallbladder, acute and chronic cholecystitis, and hyperplasia associated with pancreaticobiliary maljunction, and also cancer. Unique conditions such as sclerosing cholecystitis and cholecystitis associated with immune checkpoint inhibitor treatment can also manifest as wall thickening, as in some systemic inflammatory conditions. Gallbladder cancer, the most serious disease that can show wall thickening, can be difficult to diagnose early and to distinguish from benign causes of wall thickening, contributing to a poor prognosis. Differentiating between xanthogranulomatous cholecystitis and gallbladder cancer with wall thickening can be particularly problematic. Cancers that thicken the wall while coexisting with benign lesions that cause wall thickening represent another potential pitfall. In contrast, some benign gallbladder lesions that can cause wall thickening, such as adenomyomatosis and acute cholecystitis, typically show characteristic ultrasonographic features that, together with clinical findings, permit easier diagnosis. In this review of the literature, we describe B-mode abdominal ultrasonographic diagnosis of gallbladder lesions showing wall thickening.

Abstract
Hepatobiliary infections account for a small but clinically important proportion of emergency department presentations. They present a clinical challenge due to the broad range of imaging characteristics on presentation. Recognition of complications is imperative to drive appropriate patient care and resource utilization to avoid diagnostic pitfalls and avert adverse patient outcomes. A thorough understanding of anatomy infectious pathology of hepatobiliary system is essential in the emergency setting to confidently diagnose and guide medical intervention. Many presentations of hepatobiliary infection have characteristic imaging features on individual imaging modalities with others requiring the assimilation of findings of multiple imaging modalities along with incorporating the clinical context and multispecialist consultation. Familiarity with the strengths of individual imaging modalities in the radiologists' arsenal is imperative to guide the appropriate utilization of resources, particularly in the emergent time sensitive setting. Accurate identification and diagnosis of hepatobiliary infections is vital for appropriate patient care and management stratification.

Abstract
Xanthogranulomatous cholecystitis (XGC) is an uncommon variant of chronic cholecystitis, characterized by focal or diffuse destructive inflammatory process. The importance of XGC is that it mimics gallbladder carcinoma (GBC) both preoperatively and intra-operatively, since it can present with pericholecystic infiltration, hepatic involvement and lymphadenopathy. As a result of this misdiagnosis which is not infrequent, the patient may need to undergo an unnecessary radical cholecystectomy rather than only a cholecystectomy which is associated with greater morbidity and mortality. Patients who underwent gallbladder and gallbladder-related operations during period of 5 years between 2010 and 2014 were reviewed (n = 462). A comparison of clinical, biochemical, radiological and operative features were made between patients with carcinoma gallbladder (n = 101) and xanthogranulomatous cholecystitis (n = 22). Patient with a long history of recurrent abdominal pain with leucocytosis and who on imaging are found to have a diffusely thickened gallbladder wall (p < 0.01), with cholelithiasis, choledocholithiasis and sub-mucosal hypoattenuated nodules (p < 0.05) are likely to have XGC while those with anorexia, weight loss, focal thickening of the gallbladder wall on imaging (p < 0.01) and dense local organ infiltration are more likely to have GBC. The presence of lymph nodes on imaging and the loss of fat plane interface between the liver and gallbladder are not differentiating factors. Differentiating XGC from GBC in preoperative setting is necessary to avoid radical procedures being done for a benign process. Certain clinical, radiological and intra-operative features aid in differentiating these benign and malignant process. However, the definitive diagnosis still remains a histopathological examination to avoid radical resection in patients who have a benign condition.

Abstract
Xanthogranulomatous pancreatitis (XGP) is an extremely rare cause of a cystic pancreatic mass. The pathophysiology of this process is not entirely clear but likely results from a combination of duct obstruction, infection, and repeated hemorrhage. It is difficult to differentiate this inflammatory lesion from a cystic neoplasm and, therefore, in the majority of cases XGP is misdiagnosed as a neoplasm on preoperative imaging. In this report, we describe a case of XGP, the imaging characteristics of XGP, and a differential diagnosis for a cystic pancreatic lesion.

Abstract
BACKGROUND Xanthogranulomatous cholecystitis (XGC) is an uncommon variant of chronic cholecystitis, characterized by a focal or diffuse destructive inflammatory process. The importance of XGC is that it mimics gall bladder carcinoma (GBC) both preoperatively and intra-operatively, as it can present with pericholecystic infiltration, hepatic involvement and lymphadenopathy. As a result of a misdiagnosis, which is not infrequent, the patient may undergo an unnecessary radical cholecystectomy rather than only a cholecystectomy, which is associated with a greater morbidity and mortality. The main aim of the study is to formulate a simple preoperative scoring system for diagnosis of XGC which might benefit patients by avoiding radical procedures. METHODS A retrospective study was done from all the patients who underwent gall bladder and gall bladder-related operations (benign and malignant), during a 5-year time period from 2010 to 2014 in a tertiary care centre were reviewed (n = 462). RESULTS Initial analyses of all the clinical and imaging parameters were done. Patients with a long history of recurrent abdominal pain with leucocytosis and who on imaging are found to have a diffusely thickened gall bladder wall, cholelithiasis, choledocholithiasis and submucosal hypoattenuated nodules are likely to have XGC while those with anorexia, weight loss, focal thickening of the gall bladder wall on imaging and dense local organ infiltration are more likely to have GBC. The presence of lymph nodes on imaging and the loss of a fat plane interface between the liver and gall bladder are not differentiating factors. A scoring system was made by taking statistically significant features (n = 13) of clinical and imaging parameters in initial assessment to identify the features of XGC. The same scoring system was subsequently applied to the patients who underwent cholecystectomy to study the effectiveness and the results were reviewed. CONCLUSION High value scores (≥11/13) helps in diagnosing XGC in preoperative setting. Hence, intra-operative frozen section analysis can be avoided in such cases to differentiate XGC and GBC. However in difficult cases with high suspicion of malignancy based on clinical experience, definitive diagnosis still remains a histopathological examination to avoid radical resection in patients who have a benign condition.

Abstract
Background/Aim. To assess whether the diagnostic power of longitudinal multiplanar reformat (MPR) images is superior to that of conventional horizontal images for gallbladder cancer (GBC). Methods. Between 2006 and 2010, a total of 54 consecutive patients with preoperatively diagnosed gallbladder neoplasms located in gallbladder bed were analyzed. These patients underwent cholecystectomy with resection of the adjacent liver parenchyma. The patients were divided into the GBC group (n = 30) and the benign group (n = 24). MPR images obtained by preoperative multidetector row CT (MDCT) were assessed. Results. Mucosal line was more significantly disrupted in GBC group than that in benign group (93% [28/30 patients] versus 13% [3/24], p < 0.001). Maximum (9.3 [4.2-24.8] versus 7.0 mm [2.4-22.6], p = 0.29) and minimum (1.2 [1.0-2.4] versus 1.3 mm [1.0-2.6], p = 0.23) wall thicknesses on a single MPR plane did not differ significantly; however, the wall thickness ratio (max/min) differed significantly (6.8 [1.92-14.0] versus 5.83 [2.3-8.69], p = 0.04). Partial liver enhancement adjacent to tumor on longitudinal images was more common in GBC (40.0% [12/30 patients] versus 12.5% [3/24], p = 0.03). Mucosal line disruption was the most reliable independent predictor of diagnosis (odds ratio, 8.5; 95% CI, 5.99-28.1, p < 0.001). Conclusion. Longitudinal MPR images are more useful than horizontal images for the diagnosis of GBC.

Abstract
INTRODUCTION Xanthogranulomatous cholecystitis (XGC) is often mistaken for, and may predispose to, gallbladder carcinoma (GB Ca). This study reviews the worldwide variation of the incidence, investigations, management and outcome of patients with XGC. METHODS Data from 29 studies, cumulatively containing 1599 patients, were reviewed and results summarized by geographical region (Europe, India, Far East and Americas) with 95% confidence intervals (CIs) to present variability within regions. The main study outcomes were incidence, association with GB Ca and treatment of patients with XGC. RESULTS Overall, the incidence of XGC was 1.3-1.9%, with the exception of India where it was 8.8%. The incidence of GB Ca associated with XGC was lowest in European studies (3.3%) varying from 5.1-5.9% in the remaining regions. Confusion with or undiagnosed GB Ca led to 10.2% of patients receiving over or under treatment. CONCLUSIONS XGC is a global disease and is associated with GB Ca. Characteristic pathological, radiological and clinical features are shared with GB Ca and contribute to considerable treatment inaccuracy. Tissue sampling by pre-operative endoscopic ultrasound or intra-operative frozen section is required to accurately diagnose gallbladder pathology and should be performed before any extensive resection is performed.

Abstract
INTRODUCTION: Xanthogranulomatous cholecystitis (XGC) is a rare variant of cholecystitis and reported incidence of XGC varies from different geographic region from 0.7% -9%. Most of the clinicians are not aware of the pathology and less evidence is available regarding the optimal treatment of this less common form of cholecystitis in the present era of laparoscopic surgery. MATERIALS AND METHODS: A retrospective cohort study was conducted in a tertiary care university hospital from 1989 to 2009. Histopathologically confirmed XGC study patients (N=27) were compared with non-Xanthogranulomatous cholecystitis (NXGC) control group (N=27). The outcomes variables were operative time, complication rate and laparoscopic to open cholecystectomy conversion rate. The study group (XGC) was further divided in to three sub groups; group I open cholecystectomy (OC), laparoscopic cholecystectomy (LC) and laparoscopic converted to open cholecystectomy (LCO) for comparative analysis to identify the significant variables. RESULTS: During the study period 6878 underwent cholecystectomy including open cholecystectomy in 2309 and laparoscopic cholecystectomy in 4569 patients. Histopathology confirmed xanthogranulomatous cholecystitis in 30 patients (0.43% of all cholecystectomies) and 27 patients qualified for the inclusion criterion. Gallbladder carcinoma was reported in 100 patients (1.45%) during the study period and no association was found with XGC. The mean age of patients with XGC was 49.8 year (range: 29-79), with male to female ratio of 1:3. The most common clinical features were abdominal pain and tenderness in right hypochondrium. Biliary colic and acute cholecystitis were the most common preoperative diagnosis. Ultrasonogram was performed in all patients and CT scan abdomen in 5 patients. In study population (XGC), 10 were patients in group I, 8 in group II and 9 in group III. Conversion rate from laparoscopy to open was 53 % (n=9), surgical site infection rate of 14.8% (n=4) and common bile duct injury occurred one patient in open cholecystectomy group (3.7%). Statistically significant differences between group I and group II were raised total leukocyte count: 10.6±3.05 vs. 7.05±1.8 (P-Value 0.02) and duration of surgery in minutes: 248.75±165 vs. 109±39.7 (P-Value 0.04). The differences between group III and group II were duration of surgery in minutes: 208.75±58 vs. 109±39.7 (P-Value 0.03) and duration of symptoms in days: 3±1.8 vs. 9.8±8.8 (P-Value 0.04). The mean hospital stay in group I was 9.7 days, group II 5.6 days and in group III 10.5 days. Two patients underwent extended cholecystectomy based on clinical suspicion of carcinoma. No mortality was observed in this study population. Duration of surgery was higher in XGC group as compared to controls (NXGC) (203±129 vs.128±4, p-value=0.008) and no statistically significant difference in incidence proportion of operative complication rate were observed among the group (25.9% vs. 14.8%, p-value=0.25. Laparoscopic surgery was introduced in 1994 and 17 patients underwent laparoscopic cholecystectomy and higher conversion rate from laparoscopic to open cholecystectomy was observed in 17 study group (XGC) as compared to 27 Control group (NXGC) 53%vs.3.3% with P-value of < 0.023. CONCLUSION: XGC is a rare entity of cholecystitis and preoperative diagnosis is a challenging task. Difficult dissection was encountered in open as well in laparoscopic cholecystectomy with increased operation time. Laparoscopic cholecystectomy was carried out with high conversion rate to improve the safety of procedure. Per operative clinical suspicion of malignancy was high but no association of XGC was found with gallbladder carcinoma, therefore frozen section is recommended before embarking on radical surgery.

Abstract
OBJECTIVE To describe the differential diagnosis and treatment options for xanthogranulomatous cholecystitis (XGC), the presentations and management of 68 patients were described. SUBJECTS AND METHODS Demographical and clinical data from 68 cases of XGC treated between January 2004 and January 2010 were analyzed. Clinical characteristics, radiological and surgical findings, histopathological features and postoperative recoveries were recorded. Clinical features of laparoscopic cholecystectomy versus open surgery and XGC versus gallbladder (GB) cancer were compared. RESULTS The CA19-9 levels of XGC and coexisting GB cancer were significantly different (p = 0.0034). In radiological findings, focal thickening of the GB wall was more frequent in coexisting GB cancer, early enhancement of the GB was observed more often in coexisting GB cancer, and lymph node enlargement was seen more often in coexisting GB cancer (p < 0.05). There were also significant differences between laparoscopic and open surgery for CA19-9, intramural hypoattenuated nodule, pericholecystic invasion, lymph node enlargement and maximum thickness, focal thickening, heterogeneous enhancement and early enhancement of the GB wall (p < 0.05). These findings were confirmed by multivariate analysis. CONCLUSIONS Ultrasound, computed tomography scan and intraoperative frozen section were the helpful modalities for XGC diagnosis. CA19-9 (>37 kU/l), pericholecystic invasion, lymph node enlargement (>10 mm), and focal thickening and early enhancement of the GB wall were the criteria for open surgery. In some selected cases, laparoscopic cholecystectomy was preferable.

Abstract
Xanthogranulomatous cholecystitis is an unusual inflammatory disease of the gallbladder characterised by severe proliferative fibrosis and the accumulation of lipid-laden macrophages in areas of destructive inflammation. Its macroscopic appearance may occasionally be confused with gallbladder carcinoma. The authors present a case of xanthogranulomatous cholecystitis with type 3 choledochal cyst in a 20-year-old man who was referred to our hospital with a 1-week history of abdominal pain and fever. He underwent endoscopic sphincterotomy and then open cholecystectomy. A histological diagnosis of xanthogranulomatous cholecystitis was made.

Abstract
Xanthogranulomatous cholecystitis is an unusual inflammatory disease of the gallbladder characterized by severe proliferative fibrosis and the accumulation of lipid-laden macrophages in areas of destructive inflammation. Its macroscopic appearance may occasionally be confused with gallbladder carcinoma. We present a case of perforated xanthogranulomatous cholecystitis presenting as biloma. An 80-year-old woman was referred to our hospital with a 1-week history of abdominal pain and febrile sensation. Abdominal CT showed a biloma in the subhepatic area. The follow-up CT showed that the biloma increased in size. Therefore, ultrasonography-guided aspiration was performed. The aspirated fluid/serum bilirubin ratio was greater than 5, which was strongly suggestive of bile leakage complicated by perforated cholecystitis. She underwent a laparoscopic cholecystectomy with cyst aspiration and adhesiolysis. A histological diagnosis of perforated xanthogranulomatous cholecystitis was made.

Abstract
OBJECTIVE The purpose of this presentation is to review the sonographic spectrum of disease entities evaluated by right upper quadrant (RUQ) sonography on an emergent basis. METHODS Right upper quadrant sonography was performed on an emergent basis in patients who came to the emergency department with signs and symptoms suspicious for or simulating acute cholecystitis or diseases of the liver and biliary tree. RESULTS A wide gamut of acute and chronic cholecystitis and diseases of the liver and biliary tree were visualized on RUQ sonography. Several other entities in addition to hepatic and biliary disease were also suspected on sonography and further evaluated by computed tomography. CONCLUSIONS Right upper quadrant sonography is the first line of imaging in patients with signs and symptoms of hepatic, gallbladder, or biliary disease as well as RUQ pain. Patient triage or additional imaging may be obtained on the basis of emergent RUQ sonographic findings.

Abstract
INTRODUCTION Xanthogranulomatous cholecystitis (XGC) is an uncommon variant of chronic cholecystitis characterised by marked thickening of the gallbladder wall and dense local adhesions. Pre-operative and intra-operative diagnosis is difficult and it often mimics a gallbladder carcinoma (GBC). Laparoscopic cholecystectomy (LC) is frequently unsuccessful with a high conversion rate. A series of patients with this condition led us to review our experience with XGC and to try to develop a care pathway for its management. PATIENTS AND METHODS A retrospective review of the medical records of 1296 consecutive patients who had undergone cholecystectomy between January 2000 and April 2005 at our hospital was performed. Twenty-nine cases of XGC were identified among these cholecystectomies. The clinical, radiological and operative details of these patients have been analysed. RESULTS The incidence of XGC was 2.2% in our study. The mean age at presentation was 60.3 years with a female:male ratio of 1.4:1. Twenty-three patients (79%) required an emergency surgical admission at first presentation. In three patients, a GBC was suspected both radiologically and at operation (10.3%), but was later disproved on histology. Seventeen patients (59%) had obstructive jaundice at first presentation and required an endoscopic retrograde cholangiopancreatography (ERCP) before LC. Of these, five had common bile duct stones. Abdominal ultrasound scan showed marked thickening of the gallbladder wall in 16 cases (55%). LC was attempted in 24 patients, but required conversion to an open procedure in 11 patients (46% conversion rate). A total cholecystectomy was possible in 18 patients and a partial cholecystectomy was the choice in 11 (38%). The average operative time was 96 min. Three patients developed a postoperative bile leak, one of whom required ERCP and placement of a biliary stent. The average length of stay in the hospital was 6.3 days. CONCLUSIONS Severe xanthogranulomatous cholecystitis often mimics a gallbladder carcinoma. Currently, a correct pre-operative diagnosis is rarely made. With increased awareness and a high index of suspicion, radiological diagnosis is possible. Preoperative counselling of these patients should include possible intra-operative difficulties and the differential diagnosis of gallbladder cancer. Laparoscopic cholecystectomy is frequently unsuccessful and a partial cholecystectomy is often the procedure of choice.

Abstract
AIM: To determine the sonographic features of xantho-granulomatous cholecystitis (XGC), which could improve imaging diagnosis.
METHODS: The sonographic features of 32 patients with surgically resected XGC were retrospectively evaluated on the basis of the surgical and pathological findings. The patients were 15 women and 17 men, aged from 21 to 88 (mean 55.3) years.
RESULTS: The gallbladder wall was thickened in all patients. Among the 32 cases, 15 (46.9%) were between 4 mm to 6 mm; 14 (43.8%) were between 7 mm to 10 mm; 3 (9.3%) were between 11 mm to 22 mm. On the membranous surface of the gallbladder wall, 20 (62.5%) were smooth, while 12 (37.5%) were uneven. Other manifestations included intramural hypoechoic nodule in 5 (15.6%), intramural cholelithiasis in 1 (3.1%), and cholelithiasis 30 (93.8%), respectively. Two patients (6.3%) had liver hypoechoic or iso-echoic mass resulted from the infiltration of XGC.
CONCLUSION: Sonographic manifestations present thickened gallbladder wall, with intramural hypoechoic nodules and/or cholelithiasis. Sonographic examination can reveal the surgical and pathological findings of the XGC.

Abstract
A diverse spectrum of benign tumors and tumorlike lesions arises from the gallbladder and bile ducts, and despite their diversity, these lesions share common embryologic origins and histologic characteristics. Although these lesions are relatively uncommon, their importance lies in their ability to mimic malignant lesions in these locations. Benign neoplasms are derived from the epithelial and nonepithelial structures that compose the normal gallbladder and bile ducts. The epithelium gives rise to adenomas, cystadenomas, and the unusual condition of biliary papillomatosis. Granular cell tumors, neurofibromas, ganglioneuromas, paragangliomas, and leiomyomas are examples of benign tumors that may originate from nonepithelial structures. Tumorlike lesions are more commonly found in the gallbladder and include xanthogranulomatous cholecystitis, adenomyomatous hyperplasia, cholesterol polyps, and heterotopias. In the clinical setting of a patient with nonspecific abdominal complaints or symptoms of biliary obstruction, the discovery of a gallbladder or bile duct polyp or mass, gallbladder wall thickening, or biliary stricture is most often indicative of malignancy. However, the differential diagnosis should include benign tumors and tumorlike lesions. The preoperative determination of a benign lesion may significantly alter therapy and patient prognosis.

Abstract
OBJECTIVE The purpose of our study was to evaluate the sonographic and CT features of xanthogranulomatous cholecystitis, correlating the pathologic and surgical findings. MATERIALS AND METHODS Xanthogranulomatous cholecystitis was pathologically diagnosed in 26 patients from January 1996 to August 1998. The patients were 15 women and 11 men with a mean age of 63 years. All patients had preoperative sonography and nine also underwent CT In five patients, sonography was performed on the surgical specimen. Clinical indications for imaging included cholecystitis (14 patients), biliary colic (six patients), stone-induced pancreatitis (three patients), tumor (two patients), and gallstone ileus (one patient). RESULTS The most characteristic sonographic finding, confirmed by sonographic study of the surgical specimens, was the presence of hypoechoic nodules or bands in the gallbladder wall, which were seen in 35% of the patients. Cholelithiasis and a thickened gallbladder wall were frequent findings. The most characteristic (specific) CT finding was a hypodense band in the gallbladder wall, seen in 33% of the patients. Two of twelve patients who underwent laparoscopic cholecystectomy required conversion to open surgery. CONCLUSION Although the preoperative imaging diagnosis of xanthoganulomatous cholecystitis is difficult, the presence of hypoechoic nodules or bands in the gallbladder wall on sonography or of a hypodense band around the gallbladder on CT, is highly suggestive of this disease.
