Diabetes is the most common cause of neuropathy. Focal diabetic neuropathy, although less common than entrapment neuropathy, clinically mimics entrapment neuropathy. This article depicts the spectrum of MR abnormalities in diabetic subjects- from abnormal T2 hyperintensity and fascicular enlargement in the acute and subacute stages to atrophic-appearing fascicles with intraepineurial fat deposition in the chronic stage-on high-resolution high-field (3-T) MRI.
A spectrum of imaging abnormalities is observed in diabetic neuropathy. It is important for radiologists to understand the pathophysiology and recognize high-resolution MR appearances of these lesions and of related entities in the differential diagnosis for appropriate diagnosis and patient treatment.
糖尿病是神经病的最常见病因。局灶性糖尿病性神经病虽然不如嵌压性神经病常见,但临床上与嵌压性神经病相似。本文描述了高分辨率高场(3-T)MRI 下糖尿病患者的磁共振异常表现范围——从急性和亚急性期的 T2 高信号异常和束状增粗到慢性期的束状萎缩伴神经内膜脂肪沉积。
糖尿病性神经病可见一系列影像学异常。放射科医生了解这些病变的病理生理学以及认识到相关病变的高分辨率 MR 表现,对于正确诊断和患者治疗非常重要。
