Hepatic sarcoidosis with atypical radiological manifestations: A case report

Sarcoidosis is a multisystemic inflammatory disease of unknown origin characterized by the formation of noncaseating granulomas and accumulation of inflammatory cells. Sarcoidosis most commonly affects the lungs and lymphoid system. However, the liver can also be involved in 50%-65% of cases. On magnetic resonance imaging, sarcoidosis lesions usually present as hypointense lesions on all sequences. However, we present a rare case of nodular liver sarcoidosis presenting with T2 hyperintense lesions. In addition, while most cases of hepatic nodular sarcoidosis present with multiple small hepatic nodules, liver masses of our case are larger than usual. Moreover, this case suggested that when intact vascular structures penetrating liver nodular lesions are observed as in the current case, liver sarcoidosis can be included in a list of differential diagnosis.
