Which is the second most common benign liver mass?

• A. Hemangioma
• B. Focal Nodular Hyperplasia (FNH)
• C. Infantile Hemangioendothelioma
• D. Kasabach-Merritt Syndrome

Answer: (B)

The question tests how common benign liver masses are, specifically which lesion stands as the second most frequent after hemangioma. Hemangiomas are the most common benign liver tumor in adults, and focal nodular hyperplasia (FNH) is the next most common. FNH is a benign hepatocellular lesion that often occurs in women of reproductive age and is typically discovered incidentally. On imaging, it commonly has features of a hypervascular lesion with a characteristic central scar. The scar and the overall enhancement pattern help distinguish it from other masses. The other options don’t fit as the second most common benign liver mass: infantile hemangioendothelioma occurs in infancy, and Kasabach-Merritt syndrome is a coagulopathy associated with certain vascular tumors rather than a common benign liver mass.
