Abstract

The case history is detailed of a 55-year-old woman who was investigated for persistent pyrexia and anaemia. A liver biopsy specimen showed an unusual lesion of the small intrahepatic arteries. Many of these vessels showed circumferential replacement of their adventitial coat by a non-caseating granuloma whilst others showed localized granulomata focally interrupting the adventitial coat. The medial and intimal coats of the affected arteries were normal.

This was an intrahepatic granulomatous arteriopathy of unknown origin. The patient responded promptly and completely to steroid therapy.
