title: Focal laminar cortical MR signal abnormalities after subarachnoid hemorrhage.
abstract: In the autopsy studies of patients with delayed ischemic neurological deficits after subarachnoid hemorrhage, a predominance of cortical lesions has been observed. Similar to the autopsy descriptions in the literature, we present magnetic resonance images visualizing focal laminar cortical lesions around a fissure or sulcus in two patients, who initially did not undergo surgery, with delayed ischemic neurological deficits. This magnetic resonance imaging pattern may provide a clue to the diagnosis if the patient does not present to the emergency room with the acute hemorrhage but with delayed ischemic neurological deficits.
