We describe a case of classical polyarteritis nodosa (PAN) with viscer
al aneurysms presenting with renal infarction and hypertension. The fe
male patient also had all the laboratory features of the antiphospholi
pid syndrome (APS) and 2 months into her illness developed a large ili
ofemoral thrombosis, She responded well to immunosuppressive therapy a
nd anticoagulation. Repeat arteriogram shelved regression of the visce
ral aneurysms. The link between PAN and APS, and the therapeutic dilem
ma posed by this association, are discussed.
