Contrast-enhanced CT ((a) coronal; (c) axial) and MRI (T2-weighted; (b) coronal; (d) axial). Note the numerous well-defined soft-tissue densities in the upper neck, which represent dilated, low-flow, venous channels (solid arrows, a-d). To avoid clutter, only some are pointed out. Calcified phleboliths are also notable within the dilated venous channels, which are commonly seen in low-flow venous malformations (arrow heads, b, c).

The patient underwent contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) scans (Figure 1) as part of the workup for her symptoms. The CT scan showed multiple, bilateral, enlarged, venous malformations in the neck and posterior to the ears (Figures 1(a) and 1(c)). The T2-weighted MRI (Figures 1(b) and 1(d)) scan showed similar findings.
