Adrenal Anatomy

Abnormal adrenal anatomy is effectively identified using high-resolution computed tomography scanning and perhaps magnetic resonance imaging. 

Abnormal adrenal anatomy is effectively identified using high-resolution CT scanning and perhaps MRI. Nodules as small as 1 to 1.5 cm on the adrenal cortex are easily identified by CT. With the use of thin-section scanning, nodules as small as 3 to 5 mm can be visualized. ...

Variant anatomy of the ovarian arteries includes the gonadal artery originating from the renal artery in about 20% of individuals [2]. Very rarely the artery arises from the adrenal, lumbar, or iliac arteries [2]. In some cases, the right ovarian artery passes behind the cava and over the right renal vein. The left ovarian artery will occasionally also pass over the left renal vein [2], There is very rarely a common trunk of left and right gonadal arteries, and occasionally there are multiple gonadal arteries.
