Abnormal findings on chest x-ray may be found in Kawasaki disease, however, they are non-specific and may include peribronchial cuffing, reticulogranular pattern, pleural effusion, atelectasis, and air trapping. In rare circumstances, several years after resolution of the first episode within the elderly population, calcifications of the coronary artery will lead to coronary artery aneurysms. These aneurysms may be visualized using a plain radiograph. This presentation is described as an “Aunt Minnie” sequelae of Kawasaki disease.

• Non-specific findings on chest x-ray in Kawasaki disease may include the following:^[1]
  • Peribronchial cuffing
  • Reticulogranular pattern
  • Pleural effusion
  • Atelectasis
  • Air trapping
• Within the elderly population in rare circumstances, years after resolution of the first episode, calcifications of the coronary artery will lead to coronary artery aneurysms. These aneurysms may be visualized using a plan radiograph. This presentation is described as an “Aunt Minnie” sequelae of Kawasaki disease.^[2]
