[Acute postoperative mononeuropathy in a patient with type II diabetes mellitus]. / Mononeuropatía aguda postoperatoria en un paciente con diabetes mellitus tipo II.

Diabetes mellitus is an endocrinologic illness that affects multiple systems. One of then is the nervous system. It has been attempted to establish a relationship between metabolic abnormalities associated with diabetes and the degree of nervous system affectation. We present a case of mononeuritis involving the left peroneal nerve which occurred suddenly during the postoperative phase of a thoracoplasty in a patient with type II diabetes mellitus. The clinical picture was associated with a hyperglycemic nonketotic decompensation. We analyze the precipitating factors and their possible prevention.
