Chronic Subdural Hematomas - MRI

Note nicely depicted compartmental anatomy of the bilateral frontal Chronic Subdural Hematomas. Subdural space being only a potential anatomic compartment and only visible in case of such fluid collections. Note especially on FLAIR the high signal of fluid collections that is due to high protein content. Also observe the normal subarachnoid space (black - CSF signal) that follows sulci.
