CASTRO BONSIGNORE, Lucía  and  HIGGIE REGGIARDO, Juan Ramón. Diabetic striatopathy as a rare complication of diabetes. Case report. Rev. Urug. Med. Int. [online]. 2022, vol.7, n.3, pp.58-64.  Epub Dec 01, 2022. ISSN 2393-6797.

Diabetic striatopathy refers to a clinical-radiological syndrome caused by chorea-ballismus and increased striatal signal in the image, either tomography or magnetic resonance imaging of the skull. Although there are no epidemiological studies, a prevalence of less than 1/100,000 inhabitants is estimated. It has classically been documented in elderly women, Asian descent, with type 2 diabetes and a non-ketotic hyperosmolar hyperglycemic state. But in recent years it has been reported in a wide variety of diabetic patients. It is characterized by being reversible, with specific treatment of hyperglycemia. Some patients require the use of other drugs for symptomatic treatment while euglycemia is achieved. Cases of persistence of movements and atrophy of the caudate have been reported, when an adequate and timely diagnosis and treatment are not performed. Recurrence reaches 4 to 20%, so it is important to establish a close follow-up of these patients. We present two cases of diabetic striatopathy, a 72-year-old woman and a 73-year-old man, both presented with acute hemichorea, but with different evolution and treatment.
