Abstract

An 81 year-old male patient presented with rapid enlargement of left lateral neck mass, diagnosed two months earlier as cervical nontuberculous mycobacterial lymphadenitis. Abscess formation and impending rupture related to aggravation of nontuberculous mycobacterial lymphadenitis was highly suspected. Unexpectedly, blood flow was detected by Doppler ultrasonography, which indicated possible vascular mass. Computed tomography demonstrated a $6.0cm{\times}4.0cm$ sized enhancing mass consistent with pseudoaneurysm of internal carotid artery. The patient underwent pseudoaneurysmectomy. Surgical drainage without adequate evaluation might have led to potentially life-threatening condition. We describe this rare case with importance of imaging screening in a neck mass.

경동맥에서 발생하는 가성동맥류는 비교적 드문 질환으로 주로 외상, 감염, 수술의 합병증 또는 방사선 치료 후에 합병증으로 발생할 수 있다. 비정형 결핵성 림프절염에 의한 경동맥 가성동맥류는 거의 보고된 바 없으며 따라서 비정형 결핵성 림프절염이 동반된 환자에서는 급성악화에 의한 농양형성으로 오인될 수 있다. 비정형 결핵성 림프절염으로 치료중인 81세 남자 환자에서 이러한 경험을 하였기에 문헌고찰과 함께 보고하고자 한다.
