Real-time sonography of the abdomen indicated a dilated common bile duct (CBD; Figure 1(a)), but the gallbladder, liver, pancreas, spleen, and both kidneys appeared normal. CMV antibodies (IgM 400 and IgG 500). pp65 antigen was also positive, and real-time polymerase chain reaction (PCR) confirmed the presence of CMV DNA. Control sonography of the abdominal organs showed that the CBD had a normal appearance (Figure 1(b)).
