Man with a Forehead Mass: Detection of a Forehead Pseudoaneurysm with Bedside Ultrasonography
Figure 1
Ultrasound images of patient’s pseudoaneurysm. (a) B-mode ultrasonography shows a fluctuant mass with internal echoes similar to an abscess. Dynamic images would reveal wave-like flow through the mass suggestive of communication with a vessel lumen. (b) Color Doppler ultrasonography confirms vascular communication and pulsatile flow. (c) Color Doppler ultrasonography zoomed in on the pseudoaneurysm neck further confirms communication of pseudoaneurysm with an arterial lumen (see Supplementary material which is available online at http://dx.doi.org/10.1155/2014/647175).
