경부 종물로 발현된 원발성 경정맥류

Abstract

Venous ectasia, also called phlebectasia or venous aneurysm, is an isolated saccular or fusiform dilatation of a vein. Ectasia of the internal jugular vein was once considered rare, but is increasing in apparent frequency due to the wide use of noninvasive diagnostic modalities. A 57-year-old woman was referred for right neck discomfort that had developed 1 month earlier. She complained of a non-painful right neck swelling, located anteromedial to the sternocleidomastoid muscle. Computed tomography and color Doppler ultrasonography showed a 2×1.7-cm right internal jugular venous ectasia. The size of the jugular venous ectasia decreased after compression with a probe and increased during the Valsalva maneuver. Here, we report the first Korean case of primary internal jugular venous ectasia, which presented as an asymptomatic right neck swelling.
