Outline the Bilateral Subdural Hematomas

(Left) MRI axial T1 weighted image; (Right) MRI coronal T2 weighted image. 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. Note the bilateral subdurals, more prominent on the left. On both T1 and T2 scans, the subdurals are bright, denoting extracelluar methemoglobuin.
