Coronavirus disease 2019 (COVID-19) is known to be primarily a viral infection affecting the pulmonary system leading to severe pneumonia and acute respiratory distress syndrome. COVID-19 has also been found to affect the neurological system causing various nerve palsies. While some studies have suggested these neurological manifestations may indicate severe disease, cranial nerve palsies in the setting of COVID-19 infection have been linked to improved patient outcomes and mild viral symptoms. We present a case of a 55-year-old male with confirmed COVID-19 infection presenting with third cranial nerve palsy. Since his hospital course remained unremarkable, he was treated supportively for his COVID-19 infection and remained stable on room air during his hospitalization. No causative factors other than COVID-19 were identified as a cause for his cranial three nerve palsy which resolved spontaneously during outpatient follow-up. Although different cranial nerve palsies associated with COVID-19 infection have been identified in the literature, the pathogenesis and prognosis of cranial nerve palsy is still unclear. This case emphasizes the need for continued symptom monitoring and identification in patients diagnosed with COVID-19.
