Multiple Choice

In what scenarios is a liver biopsy essential in the workup of a liver mass?

Biopsy is used when you need a definite tissue diagnosis to guide what to do next. In liver masses, imaging with contrast-enhanced CT or MRI can often distinguish most benign from malignant lesions, or even identify a specific tumor type. Therefore biopsy is not done for every lesion. The biopsy is essential when imaging cannot give a clear diagnosis (non-diagnostic imaging) or when knowing the exact histology would change the treatment plan—for example, distinguishing hepatocellular carcinoma from metastasis or cholangiocarcinoma, or when the tumor type would determine a specific systemic therapy or clinical trial. Avoiding biopsy is favored when imaging is already diagnostic and biopsy wouldn’t change management, because biopsy carries risks such as bleeding and, rarely, tumor seeding along the needle track.
