Case Report

Multiple Venous Malformations as a Cause of Pulsatile Tinnitus

Figure 1

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).
