Angiographic findings of the left internal cerebral artery. MCA occlusion was shown (A, arrow). Image after thrombectomy showed revascularization of the occluded artery (B). MCA: middle cerebral artery.

Endovascular thrombectomy was performed and subsequent imaging showed successful revascularization (Fig. 1).
TEE revealed a pedunculate tumor-like lesion approximately 7 mm in size (A, short axis view, arrow), the thrombus was highly mobile and located on the proximal ascending aorta (B, long axis view, arrow). TEE: trans-esophageal echocardiogram.

TEE revealed a pedunculate tumor-like lesion on the proximal ascending aorta (Fig. 2).
Cardiac CT images showed a corresponding contrast medium filling defect on the ascending aorta. The aorta itself did not show atherosclerotic changes (A, short axis view, arrow; B long axis view, arrow). CTA images taken 2 days before cardiac CT were not able to detect the lesion (C, short axis view; D, long axis view). CT: computed tomography, CTA: CT angiography.

Cardiac CT showed a corresponding contrast medium filling defect (Fig. 3).
Follow-up cardiac CT images and TEE at 3 weeks post-stroke showed complete resolution of the aortic thrombus (A, cardiac CT; C, TEE). There was no recurrent thrombus in the follow-up images at 6 weeks post-stroke (B, cardiac CT; D, TEE). CT: computed tomography, TEE: trans-esophageal echocardiogram.

Follow-up TEE was performed 3 weeks after admission, and showed complete resolution of the thrombus (Fig. 4). He had no recurrent lesion on TEE or cardiac CT at the 6-week follow-up (Fig. 4) and was transferred to a rehabilitation hospital.
