Background: Hemifacial spasm is characterised by twitching of the muscles innervated by facial nerve. It is believed to result from hyperexcitability of the facial nerve nucleus or ephaptic transmission within the proximal facial nerve segment of the facial nerve nucleus. Often we observe spasm in an awakening situation. Actually contractions persist during sleep. To our knowledge, there were no reports on how it manifests under disturbance of consciousness. Herein we report a case whose symptoms sustained under coma status.Case presentation: A 74-year-old female suffered from right side primary hemifacial spasm for 20 years and used to accept botulinum toxin injection in our clinic. Unfortunately she was carried to emergency department in our hospital after traumatic right pneumothorax by accident. During emergency rescue cardiac arrest and apnea happened. She was then hospitalized in emergency intensive care unit for further therapy. During hospitalization, she was under coma status. Vital signs were stable and symptoms of hemifacial spasm sustained. A multidisciplinary consultation was request to identify whether it was focal cortical seizures involving the right side facial muscles. Physical examination revealed brief involuntary clonic or tonic contractions accompanied with the ‘Babinski-2’ sign. Synthesize the relevant data including past history, clinical manifestation and negative head computed tomography scanning, diagnosis was made as hemifacial spasm. Herein symptoms of hemifacial spasm were not life threatening and anti-epileptic drug was not necessary.Conclusions: It’s better for nonspecialists to prompt diagnose instead of under or misdiagnose the symptoms as seizures as inappropriate diagnostic or therapeutic measures may be taken inadvertently.

Background Hemifacial spasm (HFS) is a movement disorder caused by mechanical compression of the facial nerve after it has left the brainstem and is characterized by brief or sustained twitching of the muscles innervated by that nerve. Often we observe spasm in an awakening situation. Actually contractions persist during sleep. To our knowledge, there were no reports on how HFS manifests under disturbance of consciousness. Here, we report a case of primary HFS in which the patient's symptoms persisted in a coma. Case presentation A 74-year-old female with right-sided primary HFS for 20 years and had received botulinum toxin injections in our hospital. Unfortunately she was carried to emergency department after traumatic right pneumothorax by accident. During the emergency treatment, she lost consciousness due to simultaneous cardiac arrest and respiratory arrest. She was then admitted to the emergency intensive care unit for further treatment. During her hospitalization, she was in a coma with stable vital signs and persisting symptoms of HFS. Thus, a multidisciplinary consultation was requested to identify whether it was focal cortical seizures involving the right-side facial muscles. Physical examination revealed brief involuntary clonic or tonic contractions accompanied with the ‘Babinski-2 sign’. A combination of relevant data, including her past history, clinical presentation and a negative computed tomography scan of the head, led to a diagnosis of right-sided HFS. As the symptoms of HFS are not life-threatening, the use of anticonvulsants is unnecessary. Conclusions For the layperson, it is crucial to seek a multidisciplinary consultation to obtain a correct diagnosis.
