Spontanous Remission of PAN

Polyarteritis nodosa (PAN) affects mostly medium-sized arteries and sometimes small ones as well. The primary methods used to make the diagnosis are through physical examinations, biopsies of organs that are affected, and/or angiographic studies. Immunosuppressants like glucocorticoids and cyclophosphamide are usually started as soon as possible after a diagnosis. So, it’s not clear if sudden remission of PAN happens or not. Here we present a 42-year-old male who presented with right upper quadrant, right flank pain and fever. CT angiogram Aorta revealed soft tissue rind around the small to medium sized vessel in the abdomen and bilateral cortical renal infarcts of variable age in the right more than the left. A diagnosis of polyarteritis nodosa was made and the patient achieved spontaneous remission with no need for corticosteroids or immunosuppressive therapy.
