A 35-year-old female presents with a 6-month history of dull right upper quadrant discomfort. She takes oral contraceptives. Contrast-enhanced CT scan of the abdomen shows a well-circumscribed, 6 cm hypodense mass in segment IV of the liver with a central scar that enhances on delayed phases. What is the most likely diagnosis?
- A.Hepatic adenoma
- B.Focal nodular hyperplasiaCorrect answer
- C.Cholangiocarcinoma
- D.Hepatic hemangioma
Solution
Focal nodular hyperplasia (FNH) is a benign liver lesion characterized pathologically by a central fibrous scar with radiating septa. It classically shows a central scar with avid arterial enhancement and delayed enhancement of the scar on CT/MRI. Unlike hepatic adenomas, it has no malignant potential and is not strongly linked to rupture.
