MR Neuroimaging Findings in Adult Diabetic Patients- Two Case Reports

Abstract

Diabetes Mellitus (DM) can affect any part of the central and peripheral nervous systems. Significant variations in glucose levels are often symptomatic. Hypoglycaemia as well as hyperglycaemia can present a wide variety of clinical symptoms. Imaging helps by suggesting the correct diagnosis and ensuring early treatment. We hereby present two cases, one of hypoglycaemic encephalopathy and a case of diabetic striatopathy. A 40-year-old female with a 25-year-old history of type 2 diabetes was brought into the emergency room in an unresponsive state since afternoon. The blood glucose was 28 mg/dL, and immediate administration of D 25%x2 stat was done. MRI revealed hyperintensities in the bilateral hippocampi and in the cortex of the bilateral high parietal region on T2WI/FLAIR. Despite intensive medical treatment the patient’s neurologic condition didn’t improve, due to irreversible brain tissue damage, and the patient ultimately died. A 63-year-old male was brought by relatives to causality with complaints of involuntary movements of the right-side of the body since three months, but symptoms have exaggerated since three days. Newly diagnosed DM since three months was on medication T.Metformin 500 mg BD. MRI revealed T1 hyperintensities in posterior half of left putamen. Patient was put on Inj. haloperidol 0.5 mg SOS, T.Aspirin 150 mg OD, T.Atorva 20 mg HS, T.sodium valproate 200 mg BD, T.tetrabenazine 25 mg BD and T.Serenace 0.5 mg BD and patient had improved symptomatically after 15 days of treatment. Imaging can play a crucial role in diagnosis and guide treatment and markedly influence the prognosis of patient.
