Figure 1

Significant extravascular findings that provide an alternative explanation of clinical symptoms. The patient presented to the emergency room with history of motor cycle accident with acute chest pain. Computed tomographic angiography of the whole aorta shows no significant vascular finding. However, there were two significant extravascular findings that can explain clinical symptoms, i.e. fracture sternum and fracture lateral right 8th and 9th ribs and right hemopneumothorax.

Significant extravascular findings that required radiological follow up or further investigation. Patient came to hospital with history of hemoptysis and computed tomographic angiography of the whole aorta shows no significant vascular finding. However, there is a large heterogenous enhancing mass at the apex of left lung. Lung metastasis from renal cell carcinoma was diagnosed after biopsy.

Significant vascular findings. The patient presented with a history of a pulsatile abdominal mass. Computed tomographic angiography of the whole aorta shows there is a dissected aneurysm extending from the proximal descending aorta to the level of aortic bifurcation with a thrombosed false lumen.
