Granulomatous infiltration with replacement of liver parenchyma: first case report

A 76-year-old man presented with fever, weight loss and abnormal liver function tests. Imaging demonstrated a diffusely abnormal liver, and a liver biopsy revealed a fibrosing granulomatous process infiltrating and replacing liver parenchyma. There was no clinical, radiological or laboratory evidence of autoimmune liver disease, sarcoidosis, lymphoma or tuberculosis. Treatment with steroids resulted in a remarkable resolution of the clinical symptoms and radiology. This is the first case of granulomatous infiltration of the liver replacing normal hepatic parenchyma.
