Horner’s syndrome in the course of COVID-19: a case report

In December 2019, in China appeared a new infectious disease — coronavirus disease-2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Immediately it has spread worldwide. The disease manifests itself in different ways. It may be asymptomatic. It can also cause various, non-specific symptoms such as cough, fever, sore throat, rhinitis, malaise, headache, muscle pain, diarrhea, loss of smell and taste, or rash. Sometimes, the infection leads to severe pneumonia, which may cause respiratory failure and death. But there are also less frequent manifestations of the disease. For example, increasing numbers of studies reported neurological complications, such as cerebrovascular events, seizures, meningoencephalitis, encephalopathies, acute myelitis, acute facial nerve palsy, or Guillain-Barre syndrome. In our knowledge, up to now, only a few cases of Horner’s Syndrome due to COVID-19 were described. Thus, in this article, we present the case of a patient with COVID-19 pneumonia complicated by Horner’s Syndrome.
