MRI Flair images. (Left) axial; (Right) coronal. Note the large subdural collection of the left side with effacement of the sulci nearby. Subdurals are recognized by their crescent shape overlying and compressing the brain. In the elderly, they can occur following minor trauma, affecting the so-called bridging veins between the dura and brain.
