Their presence around the common bile duct (CBD) may lead to diagnostic confusion and inappropriate management.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation:<\/jats:title>\n                    <jats:p>We report the case of a 52-year-old woman with a history of cholecystectomy and post-ERCP pancreatitis who presented with chronic right upper quadrant abdominal pain. MRCP revealed beading and wall thickening of the CBD, raising suspicion for PSC or periductal CCA. Three-phase CT imaging demonstrated dilated paracholedochal collateral veins encasing the CBD. Laboratory investigations showed elevated AST, ALT, ALP, and CA 19\u20139, with declining hemoglobin and platelets during her latest admission.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical discussion:<\/jats:title>\n                    <jats:p>PSCVs can produce external compression and irregularity of the bile duct, mimicking the imaging features of malignant or inflammatory biliary conditions.
