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-Barré 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.
