Physical examination revealed a soft, nontender, nonpulsative lump at the right supraclavicular region (Figure 1).
Axial (a) and (b) coronal Multidetector Computed Tomography (MDCT) images following intravenous contrast administration and color Doppler (c) and gray scale (d) ultrasound images of an external jugular vein aneurysm. Ultrasound and MDCT showed the presence of a cystic mass (asterisks) communicating with a short neck (arrow) with the external jugular vein. The lesion presented with venous flow on colour Doppler US examination and intense contrast enhancement on MDCT.
