Hyperglycemic Hyperosmolar Syndrome With Higher Brain Dysfunction in Which Arterial Spin Labeling Revealed Abnormal Cerebral Blood Flow: A Case Report

ABSTRACT

Treatment for hyperglycemic hyperosmolar syndrome (HHS) was initiated for a transferred unconscious patient. Aphasia and agnosia remained even after metabolic improvement. Arterial spin labeling (ASL) indicated increased blood flow in the left temporal and parietal lobes. ASL may provide useful information regarding cerebral perfusion abnormalities in patients with HHS.
