The COVID-19 has a wide range of symptoms. This novel infectious disease may also trigger a vast range of neurological involvements. The current report describes a case of COVID-19 complicated with Bell's palsy. A 64-year-old woman with diabetes was admitted due to abrupt left hemifacial weakness. On examination, her left hemifacial expression ability was impaired so that her face seemed asymmetrical during smiling, and numbness around the left nasolabial fold was detected. Furthermore, her ability to wink was impaired, and her eyebrow drooped. A brain computed tomography (CT) scan did not show any abnormalities. A lung CT scan was performed, which demonstrated bilateral ground-glass opacity (GGO), along with RT-PCR results indicative of COVID-19. A diagnosis of Bell's palsy in the setting of COVID-19 infection was made. She received antiviral agents and corticosteroids. At two week follow-up, her symptoms had improved. During the COVID-19 epidemic, any newly occurred neurological involvement raises the suspicion of COVID-19 infection.
