There a left hemispheric subdural collection (maximum thickness 2.2 cm) with a mass effect on the midline structures with subfalcine herniation. It elicits high signal on T1W, T2W and FLAIR sequences with internal septations of low signal mainly on T2W and GE, indicating a late subacute subdural hematoma (free methemoglobin). Associated subarachnoid hemorrhage, best visualized on FLAIR sequence.
Case Discussion
MRI features of late subacute subdural hematoma (extracellular methemoglobin) with associated subarachnoid hemorrhage.
