Fatal intrahepatic haemorrhage in a patient with rheumatoid vasculitis: an autopsy case report

Rheumatoid vasculitis (RV) is an extra-articular complication characterised by small-to-medium vessel vasculitis associated with rheumatoid arthritis, leading to various organ involvements. However, there are few reports of RV associated with aneurysms causing intra-abdominal haemorrhage. Although the incidence of RV has recently decreased, its prognosis remains poor. We herein report a case of RV in a patient with a 1.5-year history of treatment for late-onset rheumatoid arthritis. The patient died of intrahepatic haemorrhage caused by the rupture of a hepatic artery aneurysm. RV can be challenging to diagnose clinically and is sometimes only identified at autopsy. When inflammatory findings arise that do not correspond to the activity of arthritis, careful differential diagnosis is essential.
