Small left adrenal homogeneous mild hypodense lesion, suggestive of adrenal adenoma.

Morgagni hernias are more often right-sided (~90%), most often contain omental fat (~90%) and tend to occur in overweight, middle-aged, women. They are generally asymptomatic and incidentally found in chest radiological studies.
