Abstract: Inflammatory pseudotumor is a rare benign tumor, which is histologically composed of stroma with connective tissue and mixed infiltration of lymphocytes, plasma cells, and histiocytes. We experienced a case of inflammatory pseudotumor in the liver diagnosed through the work up of fever of unknown origin (FUO). During the evaluation of FUO, well-encapsulated and hypervascular mass was found in the right lobe of the liver and we confirmed inflammatory pseudotumor through histological findings. This is the first report of pseudotumor in the liver as a cause of fever of unknown origin in Korea.
