Abdominal aortic aneurysm

Case contributed by Dr Jeremy Jones

Presentation

Abdominal pain with a pulsatile abdominal mass.

Patient Data

Age: Elderly
Gender: Male
CT

CT demonstrates an aortic aneurysm, the high attenuation peripherally (axial slices) suggests recent hemorrhage and is a feature of impending rupture.

Apical left ventricular calcification suggests prior anterior MI.

Case Discussion

A nice example of extra-luminal high attenuation in the wall of an aortic aneurysm.

A non-contrast CT should normally be included in the acute assessment of abdominal aortic aneurysm to confirm that the hyperdense crescent is there before you give contrast.
