Multiple Giant Coronary Artery Aneurysms in a Pediatric Patient with Granulomatosis with Polyangiitis

Granulomatosis with polyangiitis (GPA) is characterized by necrotizing vasculitis of small and medium sized vessels and is rarely present in the pediatric population. Cardiac manifestations in pediatric patients with GPA are extremely uncommon, with only two known reported cases associated with coronary artery aneurysms (Rehani and Nelson in Pediatrics 147:e20200932, 2021, 10.1542/peds.2020-0932;Aghaei Moghadam et al. in Case Rep Cardiol 2020:3417910, 2020, 10.1155/2020/3417910). We report a case of a 14-year-old male who presented with a 1 month history of fatigue and shortness of breath. He ultimately was found to have multiple giant coronary aneurysms in both the left and right coronaries including a giant aneurysm in the posterior descending; this has not been previously reported. The case highlights the need for complete multi-modality imaging of the coronary arteries in patients with GPA.
