ObjectiveTo explore the etiological agent, clinical manifestations, imaging findings, pathologic characteristics, diagnosis, treatment, and prognosis of xanthogranulomatous cholecystitis(XGC). MethodThe clinical data of 48 patients with XGC diagnosed by postoperative pathology from January 2003 to December 2012 were collected and analyzed. ResultsIn these 48 patients with XGC, the clinical manifestations included 40(83.3%)patients with upper right abdominal pain, 18(37.5%)patients with jaundice, 12(25.0%)patients with fever. B ultrasound examination was performed in 45 cases, in which 42 cases were diagnosed with cholecystitis, 38 cases together with cholecystolithiasis, 15 cases together with cholecystolithiasis and gallbladder neoplasm, and 3 cases together with choledocholith with bile duct dilatation. CT was performed in 30 cases, in which 25 cases were diagnosed with cholecystitis together with cholecystolithiasis, 11 cases were diagnosed with gallbladder neoplasm. MRI was performed in 22 cases, in which 18 cases were diagnosed with cholecystitis together with cholecystolithiasis, 4 cases were diagnosed with gallbladder carcinoma. Thirty-three cases were treated with open cholecystectomy, 9 patients with laparoscopic cholecystectomy, 4 patients with cholecystectomy plus choledocholithotomy and T-tube drainage, 2 patients with cholecystectomy plus partial hepatectomy. All the patients were diagnosed with XGC by postoperative pathology and recovered well without recurrence and canceration. ConclusionsXGC is a kind of benign and invasive disease without specific clinical manifestation. Bultrasound, CT, or MRI play an important role in diagnosis, but final diagnosis is mainly based on pathological detection, and surgery is the most effective treatment. The prognosis of XGC is favorable if gallbladder is completely resected.
ObjectiveTo investigate clinical value of MRI examination in diagnosis of xanthogranulomatous cholecystitis (XGC), and to analyze pathologic correlation of various imaging findings. MethodsMRI imaging data of 7 patients with XGC proved by surgery and pathology who underwent entire MRI sequences examination in Sichuan Provincial People's Hospital from Jan. 2013 to Dec. 2015, were analyzed retrospectively. The thickness and contrast enhancement of gallbladder wall, gallbladder wall nodules, completeness of gallbladder mucosa lines, gallbladder stones, and the changes around the gallbladder were focused in every patient. ResultsIn 7 patients with XGC: gallbladder wall thickening occurred in all patients, in which 2 patients were local thickening, 5 patients were diffuse thickening; ‘hypodense band sign' was found by enhance scan in 4 patients; the multiple intramural nodules were presented in 5 patients, which were low signal intensity on T1WI image and high signal intensity on T2WI image; the mucosal lines were continuous in 6 patients and discontinuous in 1 patient; 6 patients combined with cholecystolithiasis. The fat layer around the gallbladder was found fuzz in 7 patients, liver and gallbladder boundaries were not clear in 7 patients; temporal enhancement of arterial phase in liver parenchyma was observed in all patients, and 1 patient combined with liver abscess. Hilar bile duct narrowed and intra-hepatic bile duct dilated in 2 patients, intra-hepatic and extra-hepatic bile duct slightly dilated in 2 patients (lower part of the choledochus stone was found in 1 patient), liver cyst was observed in 3 patients, single or double kidney cyst was observed in 4 patients; all patients were not found intraperitoneal or retroperitoneal swelling lymph nodes. ConclusionMRI examination can accurately describe various imaging features of XGC, so MRI has important value in diagnosis of XGC.
ObjectiveTo investigate clinical value of magnetic resonance imaging (MRI) in differentiating xanthogranulomatous cholecystitis (XGC) with gallbladder cancer (GBC). MethodsMRI data of 7 patients with XGC and 13 patients with GBC proved by surgery and pathology were analyzed retrospectively. The main contents of the observation included:①Maximum thickness of gallbladder wall; ②Diffuse thickening or localized thickening of gallbladder wall; ③Enhancement pattern (uniform or nonuniform) of gallbladder wall; ④Gallbladder wall sandwiches enhancement; ⑤Gallbladder wall nodules; ⑥Completeness of gallbladder mucosa lines; ⑦Obstruction of biliary tract; ⑧Calculus in gallbladder or bile duct; ⑨Involvement of adjacent liver; ⑩Definition of surrounding fat layer; Lymphadenopathy. ResultsIn above 11 MRI comparing features, these features such as the gallbladder wall sandwiches enhancement, the gallbladder wall nodules, the completeness of gallbladder mucosa lines, the biliary obstruction, and the lymphadenopathy were statistically significant between the XGC and the GBC (P < 0.05), while the rest features such as the maximum thickness of gallbladder wall, the type of gallbladder wall thickening, the gallbladder wall enhancement pattern, the calculus in gallbladder or bile duct, the involvement of adjacent liver, and the definition of surrounding fat layer were not statistically significant between the XGC and the GBC (P > 0.05). ConclusionMRI has important values in differentiating XGC with GBC.
