A rare case of peliosis hepatis associated with idiopathic restrictive cardiomyopathy is reported. A 75-year-old man was admitted for evaluation of marked edema and jaundice. Serum total bilirubin was elevated above 20 mg/dl. The liver biopsy under laparoscopy revealed marked sinusoidal dilatation and retention of red blood cells, which was consistent with a diagnosis of peliosis hepatis. Cardiac catheterization revealed right ventricular filling disturbance without specific findings on endomyocardial biopsy, suggesting idiopathic restrictive cardiomyopathy. The level of serum total bilirubin decreased in association with improvement of edema after drip infusion of furosemide therapy.
