The complete features of the neurological complications of coronavirus disease 2019 (COVID-19) still need to be elucidated, including associated cranial nerve involvement. In the present study we describe cranial nerve lesions seen in magnetic resonance imaging (MRI) of six cases of confirmed COVID-19, involving the olfactory bulb, optic nerve, abducens nerve, and facial nerve. Cranial nerve involvement was associated with COVID-19, but whether by direct viral invasion or autoimmunity needs to be clarified. The development of neurological symptoms after initial respiratory symptoms and the absence of the virus in the cerebrospinal fluid (CSF) suggest the possibility of autoimmunity.

仍需要阐明 2019 年冠状病毒病 (COVID-19) 的神经系统并发症的完整特征，包括相关的颅神经受累。在本研究中，我们描述了在 6 例确诊 COVID-19 病例的磁共振成像 (MRI) 中看到的颅神经病变，涉及嗅球、视神经、外展神经和面神经。颅神经受累与 COVID-19 相关，但需要澄清是直接病毒入侵还是自身免疫。在最初的呼吸道症状后出现神经系统症状并且脑脊液 (CSF) 中没有病毒表明存在自身免疫的可能性。
