Image Kawasaki Disease: Giant Coronary Arteries Aneurysms Regression and Later Stenosis

Kawasaki disease; coronary aneurysm. Thirty days previously, a five-year-old boy had presented a clinical picture suggestive of Kawasaki disease (fever, generalized erythema, edema and scaling of the extremities, and inflammatory markers, such as erythrocyte sedimentation rate = 100 mm/h, CRP = 50 U, leukocytes 12,000/mm3 and platelets = 540,000/mm3). He received appropriate treatment including gamma globulin- 1g/Kg on the fifth and eighth day together with aspirin. Fig. 1- Giant diffuse left coronary artery aneurysms (1A) with a clear involution some months later (1B), albeit showing a residual giant aneurysm at the anterior descending artery (1C), which decreased progressively until 16 months following the initial treatment (1D), but developed an obstructive lesion (arrow) before th
