Acute cerebral dysfunction in diabetic ketoacidosis: survivial followed by panhypopituitarism.

We report a unique case of a 15-yr-old diabetic patient who survived ketoacidosis complicated by acute severe encephalopathy, hypopituitarism, and optic atropy. We reviewed our 25-yr experience with fatal diabetic ketoacidosis; three additional cases resembled the "cerebral edema" syndrome. We observed that (1) cerebral edema is not often documented in this syndrome, (2) the cause of the acute neuronal disturbance in these patients may be hypoxic, with cerebral edema a secondary development, and (3) development of encephalopathy was probably unrelated to overvigorour correction of acidosis and hyperglycemia in our cases.
