Abstract

Brachiocephalic venous aneurysm (BVA) development is an extremely rare, particularly as a primary vascular disorder. BVAs may be misinterpreted as lymphadenopathies owing to the variable degrees of enhancement seen in imaging studies, especially among patients with underlying malignancy. We report a BVA that mimicked lymph node metastasis on CT in a 60-year-old female who had undergone subtotal gastrectomy for stomach cancer. After follow-up chest CT with different bolus times and Doppler ultrasonography, a venous aneurysm originating from the brachiocephalic vein was diagnosed. We emphasize that, to make an accurate diagnosis, physicians should be aware of the potential diagnostic pitfalls and have a high index of suspicion for BVA when encountering certain lesions in the cervical area.

팔머리정맥류는 극히 드문 혈관질환으로서 선천성, 혹은 외상이나 염증 등의 후천성 원인에 의해 발생한다. 팔머리정맥류는 영상검사에서 다양한 정도의 조영증강을 보이기 때문에 암환자에서 경부 전이성 림프절로 오인 될 수 있다. 본 증례에서는 위암으로 위부분절제술을 받은 60세 여환에서 시행한 흉부 컴퓨터단층촬영에서 우측 빗장위부위에 조영증강되는 결절성 병변이 발견되었다. 전이성 림프절의 가능성을 고려하여 도플러 초음파 및 추적 컴퓨터단층촬영을 시행하였고 팔머리정맥에 생긴 정맥류로 진단하였다. 본 저자들은 암 환자에서 경부전이성 림프절로 의심되는 병변이 발견되었을 경우 팔머리정맥류의 가능성도 고려할 수 있어야 함을 강조한다.
