Article Abstract
Xanthogranulomatous cholecystitis (XGC) is an uncommon inflammatory disease of the gallbladder. We report a case of XGC with elevated activity of 18F-FDG and 68Ga-FAPI (fibroblast activating protein inhibitor), which mimics malignancy. Our case suggests that XGS should be considered in the differential diagnosis of cancer-like gallbladder lesions with increased 68Ga-FAPI uptake.

Type 1 autoimmune pancreatitis (AIP), IgG4-related sclerosing cholangitis (IgG4-SC), and IgG4-related cholecystitis are recognized as IgG4-related pancreatobiliary diseases. Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasonography (EUS) are crucial diagnostic modalities for these conditions. In the diagnosis of AIP, EUS-guided tissue acquisition plays an important role in obtaining histological confirmation and excluding pancreatic cancer (PC).

Objectives: To evaluate the value of contrast-enhanced ultrasound (CEUS) combined with two-dimensional shear wave elastography (2D-SWE) in the differential diagnosis of xanthogranulomatous cholecystitis (XGC) and gallbladder carcinoma (GBC).
Methods: This study included 90 patients who underwent surgical treatment from December 2021 to September 2023. Pathological results divided them into XGC (22 cases) and GBC (68 cases) groups.

Xanthogranulomatous cholecystitis (XGC) is a benign yet locally aggressive inflammatory condition that often mimics gallbladder adenocarcinoma (GBC) in clinical, radiological, and intraoperative presentation, leading to diagnostic uncertainty and potential overtreatment. This retrospective study aimed to identify distinguishing features between XGC and GBC by analyzing demographic, clinical, biochemical, radiological, and histopathological data from 133 patients who underwent cholecystectomy between 2013 and 2024. Among them, 115 were diagnosed with XGC and 18 with GBC.
