Retropharyngeal haematoma is a rare cause of rapid neck swelling that may result in fatal upper respiratory airway obstruction. Reported causes include trauma, surgery, retropharyngeal inflammation, carotid aneurysm, aberrant artery at the thoracic inlet and bleeding diathesis. We report a 90-year-old man who developed rapid and progressive neck swelling following a minor traumatic episode. Computed tomography showed a large low-density retropharyngeal haematoma extending from the skull base to the mediastinum, with suspected extravasation. The right vertebral artery angiogram confirmed contrast agent extravasation arising from a small branch artery. This was treated with temporary distal flow arrest and particle embolisation.
咽后血肿是颈部迅速肿胀的罕见原因，可能导致致命的上呼吸道梗阻。报告的病因包括创伤、手术、咽后炎症、颈动脉动脉瘤、胸廓入口处的异常动脉和出血素质。我们报告一名90岁男性，在一次轻微创伤事件后出现迅速进展的颈部肿胀。计算机断层扫描显示一个巨大的低密度咽后血肿，从颅底延伸至纵隔，怀疑有造影剂外渗。右侧椎动脉血管造影证实造影剂外渗来自一条小分支动脉。采用临时远端血流阻断和颗粒栓塞治疗。
