Which liver lesion is described as metastases and is the most frequent liver mass in cancer spread?

• A. METs
• B. Hepatoblastoma
• C. Lymphoma
• D. Kaposi sarcoma

Answer: (A)

Metastases to the liver are the most common liver mass seen with cancer spread. The liver’s dual blood supply, receiving blood from the portal vein and hepatic artery, makes it a prime target for circulating tumor cells to seed and grow. Because of this, metastatic lesions are typically the dominant liver finding in patients with cancer, often presenting as multiple nodules with variable imaging characteristics. Primary liver tumors like hepatoblastoma are mainly pediatric and not the typical lesion in adult cancer spread. Lymphoma and Kaposi sarcoma can involve the liver but are less commonly the predominant liver mass in the setting of metastatic disease. Thus, metastases best fits the description.
