case_images: Echocardiography on admission: (A) apparent right coronary aneurysm and
  (B) apparent aortic-left main trunk connection with no dilation of the
  left coronary arteries.

case_images: Mild dilation (3.2 mm) at the origin of the right coronary artery and small aneurysmal dilation of the right coronary artery (4.6 mm) were suspected (Figure 1A). Although the left main trunk wall was not clearly visible (Figure 1B), there appeared to be an aortic-left main trunk connection with no coronary arterial lesion in the left coronary artery.
case_images: Echocardiography at 12 days of illness: (A and B) right coronary artery
  bifurcated at a very proximal position.

case_images: fig2-11795468211010700
case_images: However, echocardiography at 12 days of illness failed to show the origin of the left main trunk but showed mild dilation of the right coronary artery (4.2 mm) and an abnormal bifurcation at the proximal right coronary artery (Figure 2, arrow).
case_images: Selective right coronary angiography (A) anteroposterior and (B) lateral.
  The entire left coronary artery arises from the right coronary artery,
  and the transverse trunk (arrows) passes anterior to the main pulmonary
  arteries, classified as RII-A using the Lipton criteria.. LAD, left anterior descending coronary artery; LCX, left circumflex
  coronary artery; RCA, right coronary artery; T, transverse trunk.

case_images: fig3-11795468211010700
case_images: Aortography and selective coronary arteriography at 50 days of illness confirmed the diagnosis of a single right coronary artery with no dilation at the origin of the right coronary artery (3.2 mm) (Figure 3).
