Bilateral crescent-shaped frontoparietal subdural hematoma of high signal intensity on T1, T2, and FLAIR sequences with internal sediments of low signal, indicating a late subacute subdural hematoma (methemoglobin free). Note the symmetrical mass effect on the midline structures.
Subarachnoid FLAIR hyperintensities at the frontoparietal regions most likely associated subarachnoid hemorrhage.
Case Discussion
MRI features of late bilateral subacute subdural hematoma (extracellular methemoglobin).with associated subarachnoid hemorrhage.
