In Patient 2, ECHO showed RCA dilated to 9 mm at 16 days of illness (a). At 30 days of illness, thrombus with relatively high density (2.6 × 3.2 mm, b-red arrow) was found and convex to the lumen in RCA (b). The thrombolytic treatment began six days later, and the thrombus disappeared after 10 days treatment (c). Coronary artery CTCA showed aneurysm in RCA and distal blood flow were clearly at 30 days of illness (d). At 17 months of illness onset, CTCA at a different hospital detected reoccurred thrombosis at the distal end of RCA, and it blocked the blood flow (e). After thrombolysis treatment for 2 months, the distal blood flow almost recovered (f)
