Rupturing aortic aneurysm with IMH. (a) Transverse nonenhanced CT sections demonstrate a 6-cm descending aortic aneurysm (A). IMH (open arrow) is present at inferior margin of the aneurysm associated with displaced intimal calcification (thin arrow) and directly contiguous with hemorrhage in the middle mediastinum (thick arrows). (b) Oblique thin-slab MIP of a CT angiogram shows the IMH (open arrow) at the inferior margin of the aneurysm (A) and the long track of blood (solid arrows) extending through the mediastinum and into the pleural space where a large hematoma (H) occupies nearly half of the right hemithorax and is distinct from lesser-attenuating pleural fluid and enhanced atelectatic right lung.
