In diabetic ketoacidosis, hyperglycemia and ketosis result in cerebral vasculitis, which can cause cerebral edema and thrombosis. A previously healthy, 12-year-old girl visited the emergency department with a history of vomiting, polydipsia, polyuria, decreased mentality, and a 7 kg (12%) weight loss within 1 week. She showed laboratory features of severe diabetic ketoacidosis, stuporous mentality, respiratory failure, and unilateral fixed mydriasis with contralateral hemiparesis. However, brain magnetic resonance imaging showed multifocal ischemic stroke mainly involving the left posterior cerebral artery territory, instead of uncal herniation. This case highlights the possible occurrence of ischemic stroke in children with early-stage diabetes mellitus.

Although advances in multi-detector computed tomography (CT) technique make it possible to evaluate peripheral subsegmental pulmonary arteries, several studies have reported that small peripheral embolisms may still be missed. Recently, some reports demonstrated that dual-energy CT improved the capability to detect peripheral pulmonary embolism. We report a case of lymphoma presenting as disseminated microvascular pulmonary tumor embolism, detected by perfusion images using dual energy CT.
