Thank you Dr. Duminda Suraweera for a great and unique case and presentation of GPA presenting as subacute limb ischemia.
 
Learning points:
–Vasculitides are commonly classified by vessel size (small, medium, large). The diagram below is also a great visual way to think about working up vasculitis when it is suspected
–Common clinical presentations of GPA include constitutional symptoms, and disorders of the upper and lower respiratory tract (e.g., sinusitis, hemoptysis) and renal disease (e.g.,glomerulonephritis).
