Abstract
Although the liver is often involved in sarcoidosis, the majority of patients are asymptomatic and have a normal liver function; therefore, hepatic sarcoidosis may sometimes not be recognized in clinical practice. Radiologically, most hepatic nodules show hypoenhancement on contrast-enhanced computed tomography or magnetic resonance imaging (MRI) and they are hypointense across all sequences of MRI. In this case, hepatic nodules were slightly hyperintense on T2-weighted images and contrasted from the early phases on gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid. We faced difficulties in distinguishing hepatic sarcoidosis from metastatic liver tumors with concurrent duodenal adenocarcinomas. Consequently, this case was diagnosed based on the pathological findings from a laparoscopic lateral segment hepatectomy.
