case_images: The patient had a large area of swelling to the left side of the face anterior to the tragus of the ear, along with a 2 cm laceration to the left cheek.

case_images: There was a 2 cm laceration to the left cheek, along with a large area of swelling to the left side of the face anterior to the tragus of the ear (Figure 1).
case_images: An anechoic, pulsatile, rounded, 2x2 cm structure with adjacent irregular pockets of internal echoes.

case_images: Using the high-frequency (4-12 MHz) linear transducer, B-mode scanning revealed an anechoic, pulsatile, 2x2 cm rounded structure with adjacent irregular pockets of internal echoes (Figure 2) (Video S1).
case_images: Pulsatile flow with the largest amplitude at the pseudoaneurysm neck. Not pictured is the decrease in amplitude towards the distal end of the sac. The gain is properly set high enough to detect the change in Doppler shift from blood flow, but not too high that would result in appearance of artifact. Also note how the scale along the right side of the screen is adjusted so that the waveform takes up as much of the screen as possible.
