Case data. (A–B) Preoperative computed tomography angiography (CTA) presented the lesion located in the bifurcation of the left common carotid artery without abundant blood supply in the white arrow and dashed circle area. (C-D) Preoperative magnetic resonance imaging (MRI) presented the non-homogeneous lesion in the red arrow area. (E) Preoperative electrocardiogram (ECG) presented a sinus rhythm with frequent premature ventricular beats as a duality. (F-I) The mass and hematoma were totally removed, and the vagal nerve was intact. (J) Postoperative ECG presented a sinus rhythm with occasional premature ventricular beats. (K-L) HE section presented the spindle cells arranged in small bundles.
