    Lateral medullary syndrome is a common brainstem stroke associated with a classical triad of Horner's Syndrome, ipsilateral ataxia and hypalgesia and thermoanasthesia of ipsilateral face.We report a case of a 49-year-old diabetic, non-hypertensive, postmenopausal female who presented with symptoms involving the left dorsal medulla along with right sided hemiparesis and left UMN-type facial palsy. Contralateral hemiparesis was explained by caudal extension of infarct involving the pyramids before decussation at the medulla, known as Babinski-Nageotte Syndrome. UMN-type facial palsy was attributed to involvement of hypothetical supranuclear aberrant corticobulbar fibres of facial nerve which descend down in the contralateral ventromedial medulla, decussate at level of upper medulla and then ascend in the dorsolateral medulla to reach the facial nerve nucleus. Association of these two entities with Wallenberg's Syndrome have been reported separately in literature, but not together as in this case. © The Author(s) 2019

    Abstract Background The novel coronavirus disease (COVID-19) has claimed innumerable lives globally since its onset and several extrapulmonary manifestations of the disease have been reported in association with COVID-19. Although optic neuropathy has been previously linked to a variety of infections, neuro-ophthalmological associations of SARS-CoV-2 have been sparsely reported till date. Our aim was to report the clinical profile and outcome of patients diagnosed with parainfectious/postinfectious optic neuritis (ON) associated with COVID-19. Case presentation In this case series, we have discussed the clinical presentation, laboratory parameters and outcome in a series of three patients of ON associated with COVID-19 and also compared those findings against existing literature. Among the three patients, two patients (Case 1, 3) were incidentally diagnosed with COVID-19 during the course of hospital admission and contributed to a parainfectious association with ON, while one patient (Case 2) had an antecedent history of COVID-19 as evidenced by her antibody titers thus contributing to a postinfectious association. Notably, all these patients were asymptomatic or had mild manifestations of COVID-19 and all of them tested negative for myelin oligodendrocyte glycoprotein (MOG) antibodies. They were treated accordingly and their visual outcomes were noted in follow-up. Conclusion ON with or without MOG seropositivity, probably attributed to molecular mimicry has surfaced up considerably in association with COVID-19. This article provides a comprehensive overview of clinical presentation and outcome of ON associated with parainfectious/postinfectious COVID-19 in three cases and a critical analysis of existing literature
