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 case 1, it was difficult to differentiate diffuse metastasis from alcoholic hepatitis. In case 2, 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.
