case_images: Bedside ultrasound of the posterior right thigh was performed and revealed an area of hypoechogencity without Doppler color flow concerning for a fluid collection (Figures 1 and 2).
case_images: Color Doppler ultrasound of posterior thigh hematoma.. Yellow box shows absent flow within area of hypoechogencity suggesting the
  presence of a fluid collection. The two punctate areas of color are likely
  due to either subtle movement of ultrasound probe or due to the active
  extravasation of blood noted on CT scan imaging.
