Polyarteritis Nodosa With Reversible FDG Accumulation in Vessels and Kidneys

A 59-year-old man presented with fever and lower extremity myalgia. Laboratory studies revealed elevated C-reactive protein. 18F-FDG PET/CT demonstrated FDG uptake not only in the brachial arteries, femoral arteries, and their main ramifications, which were equivalent to small- to medium-sized arteries but also in the kidneys. Angiography revealed a renal aneurysm, confirming the diagnosis of polyarteritis nodosa. The increased FDG uptake in the vessels and kidneys resolved after 6 months of glucocorticoid treatment.
