title: Erythromycin-induced hepatitis: simulator of malignancy.
abstract: A 67-year-old patient was admitted with a 2-week history of epigastric discomfort that began after an episode of upper respiratory tract infection treated with erythromycin. Results of liver function tests were abnormal. Abdominal ultrasound (US) and computed tomography showed multiple, poorly demarcated irregular lesions in both hepatic lobes, suggestive of diffuse metastatic invasion. Histologic examination of the biopsy specimen revealed drug-induced hepatitis. Ten weeks after withdrawal of the erythromycin, US showed complete resolution of the hyperechogenic liver lesions.
