No etiology for FHF was apparent with initial evaluation. One patient was found to have nearly complete replacement of hepatic parenchyma by metastasis from an occult small cell lung carcinoma identified postmortem. The other patient had lymphomatous in filtration of the liver detected by a liver biopsy. Imaging studies were performed in the patients and did not reveal any evidence of neoplastic infiltration of the liver. Neoplastic involvement of liver should be considered in the differential diagnosis of FHF of unknown etiology. The imaging studies in this setting can be misleading.展开更多
