A New Onset of Vocal Tic in an Adult Lady Secondary to Brain Metastasis

Tics are neuropsychiatric events characterized by brief, rapid motor movements or vocalizations in response to irresistible premonitory urges. They start in childhood and may or may not persist in adulthood. Adulthood-onset tics are usually an extinction of undiagnosed tics in childhood. Secondary tic disorders may be due to brain tumors, medications, or neurological disorders. In this article, we are describing a woman in her 60s who presented with a new-onset vocal tic a few years after being diagnosed with gluteal sarcoma that metastasized to the lung and brain, involving the left temporal and right occipital lobes. This case is similar to previously reported case reports of secondary tic disorders, although the type of tic, the brain region involved, and the primary tumors are different.
