A=Aortic aneurysm

arrow=mural thrombus.

T1MRI image with GADOLINIUM revealed

aorta(A)surrounded by mural thrombus.

Reference:BiblioMed Textbook-Computed Body Tomography

short arrow=intimal calcification in anterior or posterior wall

long arrow=intact calcified intimal flap

look first to calcified intimal flap,if it is disrupted this indicate dissecting aneurysm,if it is

intact ,this will be calcification in the anterior or posterior wall of aortic aneurysm............................

Reference:BiblioMed Textbook-Computed Body Tomography

Dissection of the aorta usually originates in the thorax but sometimes extends into the abdomen. Its diagnosis is based on demonstration of an intimal flap with enhancement of both the true and false lumina after intravenous administration of contrast medium



Reference:BiblioMed Textbook-Computed Body Tomography

An infected atherosclerotic aortic aneurysm, likewise, can be demonstrated on CT as multiple air bubbles seen in the wall of the aneurysm.

after contrast

A mycotic aneurysm usually has a saccular, irregular contour, and it contains little or no mural calcification. It enhances to a degree similar to the adjacent normal appearing aorta .
