A hyperosmolar non-ketotic hyperglycemia (glycemia: 86.5 mmol/L; sodium: 171 mEq/L) by a secondary diabetes due to acute pancreatitis. Vital support measures, i.v insulin infusion, i.v. hypotonic saline, and antibiotics were applied. Two computed tomography (CT) scans of the skull were obtained: when first admitted and after 48 hours of evolution.
