    Summary

    Facial myokymia, a rare dyskinesia, typically stems from brain stem lesions. This case highlights brain stem astrocytoma as a cause of facial myokymia.

    Area of Science:

    • Neurology
    • Neuroscience
    • Oncology

    Background:

    • Facial myokymia is an uncommon neurological disorder characterized by muscle fasciculations.
    • It is often associated with lesions in the brain stem, a critical part of the central nervous system.

    Observation:

    • A specific case of facial myokymia is presented.
    • The patient's electromyogram (EMG) findings were characteristic of the condition.

    Findings:

    • The underlying cause of facial myokymia in this reported case was identified as an astrocytoma.
    • The astrocytoma was located in the brain stem.

    Implications:

    • This case underscores the importance of considering brain stem tumors in the differential diagnosis of facial myokymia.
    • Further research into the neuro-oncological origins of dyskinesias may be warranted.
