A patient presented with transoral hemorrhage 3 months after CT-guided percutaneous biopsy of the masticator space, prompting concern about sentinel hemorrhage from impending carotid artery rupture related to prior radical head and neck surgery and radiation therapy. Angiographic evaluation showed the internal carotid artery to be normal but demonstrated a pseudoaneurysm of the buccal branch of the internal maxillary artery exactly corresponding to the site of prior fine-needle biopsy.
一名患者在咀嚼肌间隙CT引导下经皮穿刺活检3个月后出现经口出血，这引发了对因先前根治性头颈部手术和放疗导致颈动脉即将破裂而引起的哨兵出血的担忧。血管造影评估显示颈内动脉正常，但显示上颌内动脉颊支存在假性动脉瘤，其位置与先前细针活检部位完全对应。
