A Case of Polyarteritis Nodosa and Antiphospholipid Antibody Positivity Presenting with Intramuscular Haematoma

Abstract

Polyarteritis nodosa (PAN) is a medium-sized vessel vasculitis often presenting report as both stenotic and aneurysmal lesions. Association with antiphospholipid antibody (aPL) has also been described. Here, we reported a case of PAN with history of cutaneous vasculitis presenting as multiple territory ischemic stroke, mesenteric panniculitis, coronary artery stenosis on imaging; lupus anticoagulant (LA) was also identified, patient was treated with immunosuppressants and anticoagulation. Disease course was, however, complicated by development of thigh haematoma. Clinical manifestation of PAN and its association with aPL will be discussed.
