Case report. Computed tomography of the brain in severe hypoglycaemia.
Computed tomographic (CT) findings in a case of extreme hypoglycaemia induced by an overdose of chlorpropamide are described. Brain lesions tend to be preferentially localized along the boundary zones ("watersheds") between the territories of the main cerebral arteries. In our case, generalized brain damage occurred during severe hypoglycaemic coma. Neuropathological changes in this condition have been the subject of previous studies in experimental animals. Computed tomography allows follow-up studies of the human brain damaged by hypoglycaemic coma. Abnormalities revealed by CT probably represent reparative tissue reactions that indirectly reflect the extent of neuronal destruction.
