  • Objectives:

    Meige syndrome is a movement disorder that includes blepharospasm and oromandibular dystonias. Its etiology may be idiopathic (primary) or it may arise secondary to focal brain injury. Acute respiratory distress as a feature of such dystonias occurs infrequently. A review of the literature on Meige syndrome and the relationship between dystonias and respiratory compromise is presented.

    Methods:

    A 60-year-old woman suffered a cerebral anoxic event secondary to manual strangulation. She developed progressive blepharospasm combined with oromandibular and cervical dystonias. Neuroimaging demonstrated bilateral damage localized to the globus pallidus. Years later, she presented to the emergency department in intermittent respiratory distress associated with facial and cervical muscle spasms.

    Results and conclusions:

    Increasing frequency and severity of the disorder was noted over years. The acute onset of respiratory involvement required intubation and eventual tracheotomy. A partial therapeutic benefit of tetrabenazine was demonstrated.

  • A 27-year-old woman presented with hemotomyelia during pregnancy. Needle drainage of the spinal cord was followed by relief of symptoms. Symptoms recurred during a second pregnancy 4 years later and she presented with an avascular mass in the midcervical spinal cord. This lesion proved to be hemangioma calcificans, a densely calcified and ossified variant of cavernous angioma.
