Question

A 35-year-old woman undergoes abdominal imaging for nonspecific right upper quadrant pain. A liver mass is identified and surgically excised. The gross specimen is shown. What is the most likely diagnosis?

• A. Hepatocellular carcinoma
• B. Focal nodular hyperplasia
• C. Hepatic adenoma
• D. Metastasis

Hint:

Benign liver mass with central stellate scar = focal nodular hyperplasia.

Answer 1

The Correct Option is B

Concept: Focal nodular hyperplasia is a benign liver lesion, often seen in young to middle-aged women. Grossly, it classically shows a central stellate scar.

Step 1: Identify patient profile.
A young woman with an incidental liver mass suggests a benign liver lesion.

Step 2: Recall gross appearance.
Focal nodular hyperplasia typically has: \[ \text{Central stellate scar} \]

Step 3: Choose the diagnosis.
Among the options, central scar and benign liver mass most strongly indicate: \[ \text{Focal nodular hyperplasia} \] Therefore, the correct answer is Focal nodular hyperplasia.
