(A) April 22, 2015. Heart ultrasound showed an inner diameter of 40 mm in the ascending aorta; the descending aorta was widened with a wide inner diameter of 45 mm; there was a strip of light band and a group of low echoes with a range of approximately 21 × 18 mm. The diagnosis was aneurysm and aortic dissection. (B) April 3, 2016. Chest x-ray showed circular soft tissue density at the right cardiophrenic angle, suggesting elongation of the descending segment in the aorta. The diagnosis was aneurysm and aortic dissection. (C) July 27, 2017. Chest computed tomography showed that the descending aorta and abdominal aorta were widened, and a separation was visible. The curved high-density shadow in the right thoracic cavity was seen, and the thickest part was approximately 18 mm. The right chest wall was thickened. The diagnosis was ruptured aneurysm, aortic dissection, and right pleural effusion. (D, E) July 30, 2017. Chest computed tomography angiography showed that the ascending aorta and aortic arch were evenly thick. The descending aorta and abdominal aorta showed a floating band sign. The curved high-density shadow was seen in the bilateral thoracic cavities, and the thickest part was approximately 94 mm. The right chest wall was significantly thickened. The diagnosis was ruptured aneurysm, aortic dissection, and bilateral pleural effusion. (F) After 6 months of follow-up, chest computed tomography showed that the manifestations of chronic aneurysm and aortic dissection were still visible, while only a small arc-like liquid low-density shadow in bilateral thoracic cavities was seen, and the thickness of the chest wall on both sides was basically the same.
