Shoulder ‘Brightness’ on Ultrasound May Be a Sign of Diabetes

A shoulder muscle that appears unusually bright on ultrasound may be a warning sign of diabetes, according to a study presented at RSNA 2018.

More than 10 years ago, musculoskeletal radiologist Steven B. Soliman, DO, from Henry Ford Hospital in Detroit, began noticing a pattern when images of the deltoid muscle, the largest muscle of the shoulder, appeared bright on ultrasound. “Every time we would ask one of these patients if they were diabetic, they would say ‘yes’ or they would tell us they were borderline and not taking any medications,” Soliman said.

The observations prompted Soliman and colleagues at Henry Ford to conduct a study to see whether the brightness, or echogenicity, of the shoulder muscle could be predictive of diabetes. The results revealed that by using the echogenicity of the muscle, radiologists were able to predict type 2 diabetes, the most common type of diabetes, in almost nine out of 10 patients.

Brightness on ultrasound also was an accurate predictor of prediabetes, a condition of abnormally high blood sugar that generally progresses to diabetes without changes in lifestyle.

Worth Repeating
