Background: Prevalence of neuropathy in Diabetes in the pediatric age group is very low. Moreover, it is often a late complication of diabetes mellitus (DM) and usually related to the duration of diabetes, poor glycemic control and advanced age. We present here an interesting case of motor neuropathy as a first manifestation of Type 1 diabetes in an adolescent. Case presentation: A previously fit fourteen years old girl presented with sudden onset right foot drop. There was a history of osmotic symptoms and weight loss over the preceding last few months before presentation. Investigations revealed Type 1 diabetes mellitus. So, our patient was started on Multiple Daily Insulin Injection Regimen (MDI) as per protocol and the foot drop recovered within a period of two months. Conclusion: Mononeuropathy as a first presentation of diabetes is extremely rare. It is extremely important to assess the blood glucose in patients with peripheral neuropathy. Normalizing blood glucose levels leads to rapid neuronal recovery.
