Cranial nerve disease outside the skull base is a common cause of facial and/or neck pain, which causes significant disability for patients and frustration for clinicians. Neuropathy in this region can be traumatic, idiopathic, or iatrogenic secondary to dental and surgical procedures. MR neurography is a modification of conventional MRI techniques dedicated to evaluation of peripheral nerves and is being increasingly used for imaging of peripheral neuropathies at various sites in the body. MR neurography facilitates assessment of different causes of craniofacial pain and cranial nerves and allows elegant depiction of a multitude of regional neuropathies. This article discusses the anatomy, pathologic conditions, and imaging findings of the commonly implicated but difficult to image infratentorial nerves, such as the peripheral trigeminal nerve and its branches, facial nerve, glossopharyngeal nerve, vagus nerve, hypoglossal nerve, and greater and lesser occipital nerves.

颅外神经疾病是面部和/或颈部疼痛的常见原因，会给患者带来严重的残疾和临床医生的挫败感。该区域的神经病变可能是创伤性、特发性或医源性的，继发于牙科和外科手术。MR 神经成像技术是常规 MRI 技术的一种改进，专门用于评估周围神经，并且越来越多地用于身体不同部位的周围神经病变成像。MR 神经成像有助于评估颅面部疼痛和颅神经的不同原因，并可以优雅地描绘出多种区域性神经病变。本文讨论了常见但难以成像的颅后窝神经（如外周三叉神经及其分支、面神经、舌咽神经、迷走神经、舌下神经以及枕大神经和枕小神经）的解剖、病理状况和影像学表现。RSNA，2018 年。
