Pseudocirrhosis due to liver metastasis from lung adenocarcinoma.

Pseudocirrhosis is a radiological diagnosis of cirrhosis without histological evidence and occurs as a complication of liver metastases from solid tumors. A 50-year-old man without any previous history of liver disease was diagnosed with adenocarcinoma of the left upper lung lobe and liver metastasis. After chemotherapy, the liver metastases shrank; however, over time, the liver shrank and showed cirrhosis-like morphological changes. His performance status deteriorated due to ascites and leg edema, and chemotherapy was terminated. Physicians treating lung adenocarcinoma with liver metastases should be aware that pseudocirrhosis is a rare but important complication that can worsen performance status (PS) and hinder treatment continuation.
