In cirrhosis, an incidental small liver lesion must first be characterized noninvasively because the main concern is hepatocellular carcinoma. MRI with contrast is the best next step when the lesion is uncertain, larger than about 1 cm, or has suspicious features, since it can distinguish malignant from benign nodules with high accuracy and help determine the correct management. Biopsy is avoided in cirrhosis due to higher bleeding risk from portal hypertension and coagulopathy, and because there’s a risk of tumor seeding along the needle tract; only if imaging cannot establish the diagnosis and the result would change treatment would a biopsy be considered. If the imaging features are clearly benign and the lesion remains stable, serial imaging to monitor over time is appropriate. Immediate surgical resection or chemotherapy is not warranted without a proven malignant diagnosis and proper staging, given the risks in a cirrhotic patient and the lack of indication for such therapy in benign lesions.
