Sonography of Isolated Internal Jugular Vein Impingement and Thrombosis

Abstract

This case illustrates incidental findings of internal jugular vein (IJV) impingement and thrombosis caused by a metastatic tumor. Sonography of an asymptomatic adult female demonstrated nonocclusive deep venous thrombosis in the left IJV and an impinging vascular mass. Contrast-enhanced computed tomography confirmed compression, displacement, and obstruction of the IJV and metastasis. This case highlights the utility of sonography to identify unsuspected pathologies.
