In this case report we present a diabetic patient with isolated, pupil-sparing, incomplete inferior division third cranial nerve palsy. Laboratory tests for the evaluation of thyroid function, infection, myasthenia gravis and autoimmune diseases were normal. Cranial computed tomography, magnetic resonance imaging and magnetic resonance angiography also showed normal findings. Accordingly, diabetes related vasculopathic third nerve palsy was suggested. The ocular signs of oculomotor palsy completely disappeared 2 months later. Although this clinical entity is rarely reported, differential diagnosis with pupil-sparing third nerve palsy of other etiologies such as compression by an aneurysm or tumor still need to be investigated.
在本病例报告中，我们呈现了一名患有孤立性、瞳孔保留、不完全性动眼神经下支麻痹的糖尿病患者。评估甲状腺功能、感染、重症肌无力和自身免疫性疾病的实验室检查均正常。头颅计算机断层扫描、磁共振成像和磁共振血管造影也显示正常结果。因此，提示为糖尿病相关性血管病变性动眼神经麻痹。2个月后动眼神经麻痹的眼部体征完全消失。尽管这种临床情况很少被报道，但仍需对其与其他病因（如动脉瘤或肿瘤压迫）导致的瞳孔保留性动眼神经麻痹进行鉴别诊断。
