Contralateral Hemifacial Spasm Occurred Simultaneously in Acute Bell's Palsy

Hemifacial spasm (HFS) may develop after Bell's palsy (BP). But it was not reported that contralateral HFS occurred simultaneously in acute BP. A 25-year-old woman admitted with left HFS occurred simultaneously in acute right BP for 6 days. Past, family, and social history were unremarkable. Nerve conduction studies (NCS) and blink reflex (BR) test showed bilateral facial neuropathies. Brain MRI and cerebral angiography were normal. The symptoms and signs of HFS and BP were improved slowly after acyclovir and prednisolone therapy. Follow-up serial NCS and BR also showed a rapid improvement.
