What type of benign liver neoplasm is characterized by large blood-filled cystic spaces?

• A. Adenoma
• B. Simple cyst
• C. Cystadenoma
• D. Cavernous hemangioma

Answer: (D)

The type of benign liver neoplasm that is characterized by large blood-filled cystic spaces is a cavernous hemangioma. This type of neoplasm consists of a mass of blood vessels that form a benign tumor in the liver. The vascular nature of cavernous hemangiomas leads to the formation of large cystic spaces filled with blood instead of fluid, which is a key feature distinguishing them from other types of liver lesions. Cavernous hemangiomas typically do not cause symptoms and are often found incidentally during imaging studies. They are the most common benign vascular tumors of the liver and can vary in size, with larger ones being more likely to be discovered during imaging for other reasons. Understanding the vascular composition and the appearance on ultrasound or other imaging modalities is essential for accurate diagnosis and differentiation from other liver lesions.
