In Response to the Article “CT of Hepatic Sarcoidosis: Small Nodular Lesions Simulating Metastatic Disease”. Pol J Radiol, 2015; 80: 178–180

Sarcoidosis is a systemic disorder of unknown etiology, characterized by non-caseating epitheloid granulomas. It has been suggested that sarcoidosis results from exposure to antigens like aerosols and infectious agents in genetically predisposed individuals [2]. Virtually any organ system may be involved. Although the involvement of the abdominal viscera is less frequent as compared to pulmonary and mediastinal diseases, when it occurs, it may mimic more common infectious or neoplastic conditions and pose a perplexing diagnostic problem.
