Figure 3. CT angiogram abdominal aorta and bilateral iliofemoral lower extremity runoff with contrast showing a large hematoma (green arrows) extending from the pelvis to the iliopsoas musculature measuring approximately 25 x 10 x 6 cm at the level of the pelvis without extravasation of contrast. The arterial vasculature of the bilateral lower extremities is patent bilaterally (red arrows) but there is greatly impaired venous return at the level of the pelvis with compression of the left common iliac vein by the large hematoma. (Blue arrow is pointing to right femoral vein. Left femoral vein is compressed and not visible.).
