A 57-year-old woman with sarcoidosis was referred because of the appearance of multiple small low-attenuation areas in the liver on computed tomography (CT). A liver biopsy specimen showed chronic active hepatitis accompanied by sarcoid granulomas. The patient received prednisolone and, later, interferon-alpha. CT at 5 months of prednisolone treatment showed disappearance of the hepatic low-attenuation nodules. During long-term follow-up, however, these nodules reappeared on CT and liver cirrhosis finally developed. We present this case for two reasons: (1) hepatic sarcoidosis was associated with chronic active hepatitis C; (2) hepatic nodular lesions were evaluated by CT throughout the entire course, with CT scans having been taken from 2 years prior to their appearance.
