Diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) are potentially life-threatening complications of diabetes mellitus. Although DKA and HHS share similar features, they are distinct clinical entities requiring different treatment measures.This case illustrates that the clinical distinction between these two entities can be difficult at times, especially in children who can present with an overlapping picture.We report an interesting case of a 12-year-old whose initial presentation of diabetes was a mixed picture of hyperosmolar DKA and HHS coma complicated by myocardial strain and acute renal insufficiency. The myocardial strain resolved completely with resolution of the metabolic abnormalities.Emergency physicians should be cognizant of varied presentations of hyperglycemic emergencies in children to initiate appropriate management for better outcomes.
