Clinical Case
Case 1
A 4-year-old previously healthy girl is brought to the pediatrician for a 2-month history of intermittent, colicky abdominal pain. Over the past two weeks, her parents have noticed her eyes appear yellow, and she has been less energetic. Physical examination reveals scleral icterus, a soft, non-tender abdomen, and a palpable, smooth, round mass in the right upper quadrant. Vital signs are normal. A right upper quadrant ultrasound reveals a 4 cm cystic structure separate from the gallbladder, with associated dilation of the common hepatic duct. Liver function tests show a total bilirubin of 4.2 mg/dL (direct 3.8 mg/dL), AST 85 U/L, and ALT 110 U/L.
Q1: What is the most appropriate next diagnostic step to confirm the diagnosis and plan surgical management?
