The MRI sequences demonstrate:
- right crescent-shaped hemispheric subdural hematoma (maximum thickness 25 mm), eliciting an iso-to high signal intensity to the cortical grey matter on T1, high signal on T2, FLAIR, and GE sequences, indicating a hyperacute subdural hematoma. A mass effect is noted on the midline structures with no significant subfalcine herniation
- small left subdural hematoma (maximum thickness 6 mm) hyperintense to the cortical grey matter on T1, and FLAIR, and isointense on T2, in keeping with subacute subdural hematoma
- age-related cerebral volume loss with small vessel ischemic disease
MRI features of bilateral subdural hematoma, hyperacute on the right and subacute on the left.
