Summary table for nonketotic hyperglycemia

Etiology:	Controversial, leading hypothesis states hyperintense T1-weighted signal is secondary to unwrapping of myelin sheath and swollen gemistocytes [3,5]
Incidence:	Rare; largest published case series consists of 53 patients, majority of reported cases involve Asians [2]
Gender ratio:	Of the 53 cases with gender available, 30 females and 17 males (ratio of F to M: 1.76) [2]
Age predilection:	Range: 22–92 years, mean age of 71.1 years [2]
Risk factors:	History of poorly controlled diabetes mellitus [2]
Treatment:	Normalization of blood glucose levels with appropriate insulin therapy [2]
Prognosis:	Excellent with timely instillation of insulin therapy [2]
Findings on imaging:	MR: unilateral or asymmetric T1-weighted hyperintense BG lesion, T2-variable, susceptibility and diffusion - variable, often enhances [2]
