Acute Liver Failure with Diffuse Liver Metastasis from Breast Cancer, Not Detected by Computed Tomography: 2 Case Reports

Diffuse liver metastasis is a rare pattern of liver metastasis that is associated with hepatic failure and poor prognosis. We experienced 2 cases of acute liver failure due to diffuse metastasis that could not be detected using computed tomography. In , it was difficult to differentiate diffuse metastasis from alcoholic hepatitis. In , it was difficult to diagnose diffuse liver metastasis because the patient had no history of malignancy. When liver enzyme levels are elevated, it is necessary to consider liver metastasis as a potential cause, regardless of computed tomography findings.
