CT
Axial C+ arterial phase
Axial C+ delayed
Contrast-enhanced 4-slice CT scan of the whole aorta (only the abdominal slices are shown) in the arterial phase and subsequent scan of the abdomen 2 min. post administration of i.v. contrast.
The main finding of the arterial phase is a ruptured aneurysm of the left common iliac artery which extends into the external iliac artery. It has a maximum diameter of 10 cm and extends over a length of 14 cm. Active extravasation of contrast-enhanced blood can be seen into the large retroperitoneal haematoma.
The subsequent scan reveals massive continuing bleeding and with a notable increase of the size of the retroperitoneal hematoma which now also involves the contralateral retroperitoneum and measures about 20 x 10 x 26 cm.
