CT confirmed the patient with SIT. (A) Chest CT presented a right-sided view of the heart. (B) Abdominal CT suggested left-right viscera inversion.

Figure 1 illustrates how CT further established the patient's SIT. Figure 1A shows a right-sided image of the heart on chest CT, and Figure 1B shows a left-right visceral inversion (Figure 1B).
Interventional surgery was performed to treat BTAA. (A) Anteroposterior and lateral angiography of bilateral common carotid arteries and bilateral vertebral arteries shows the inverted arrangement of the aortic arch and its upper vessels. (B) An aneurysm (white arrows) in the middle part of the basilar artery, with a diameter of about 3 mm  x  4 mm, and the apex daughter tumor. (C) Arrow indicated successful aneurysm embolization after interventional therapy. (D) Re-examination of cerebral angiography showed a small part of tumor neck residue (arrow indicated) one year after the operation.

The left common carotid artery and the left subclavian artery were identified from an unidentified trunk that was situated on the side of the ascending aorta (Figure 2A). An aneurysm was detected in the middle part of the basilar artery, with a diameter of about 3 mm x 4 mm, and an apex daughter tumor was formed (Figure 2B). Then, a Solitaire-AB (4 mm x 15 mm) stent was released smoothly through the stent catheter, which covered the tumor neck satisfactorily and was sent into the spring coil sequentially through the microcatheter until the embolization degree was satisfied (Figure 2C). Re-examination of cerebral angiography showed a small part of tumor neck residue 1 year after the operation (Figure 2D).
