Lymph-node-first Kawasaki disease and giant coronary artery aneurysm

A 8-year-old Irish ethnicity girl presented with 3 days of fever with right-sided neck swelling which was first thought as acute tonsillitis with right-sided lymphadenitis. She was started on intravenous antibiotics. At day 7 of illness, she was diagnosed to have Kawasaki disease with clinical and biochemical evidence. Echocardiogram at day 9 of illness and subsequently CT cardiac angiogram performed revealed giant aneurysm at the right coronary artery with non-obstructing thrombus seen. The patient then commenced on clopidogrel and continued with a regular dose of aspirin. Due to the evidence of thrombus with a giant coronary aneurysm, she was also put on long-term warfarin therapy with regular monitoring of her international normalised ratio to be kept at the range of 2.0–3.0.
