Abstract:
We report a case of a 31-year-old immunocompetent male who presented with altered mental status and agitation requiring intubation. As sedation was weaned, he demonstrated choreiform movements with associated hemiballismus of the right upper and lower extremities, and he was ultimately diagnosed with cryptococcal meningitis. The patient's chorea did not terminate after the completion of induction antifungal therapy and all pharmacologic options for the management of chorea were ineffective. He underwent a successful unilateral pallidotomy using standard stereotactic methodology targeting the posterior-ventral pallidum, and his choreiform movements dramatically improved post-operatively within 48 hours.
Insights
A 31-year-old man with cryptococcal meningitis experienced severe choreiform movements. Unilateral pallidotomy successfully resolved these involuntary movements when medications failed.
Area of Science:
- Neurology
- Infectious Diseases
- Neurosurgery
Background:
- Cryptococcal meningitis can cause neurological complications.
- Choreiform movements and hemiballismus are rare but severe symptoms.
Observation:
- A 31-year-old immunocompetent male presented with altered mental status, agitation, and subsequent choreiform movements/hemiballismus.
- The patient was diagnosed with cryptococcal meningitis.
- Pharmacological treatments for chorea were ineffective.
Findings:
- Successful unilateral pallidotomy was performed using stereotactic methods targeting the posterior-ventral pallidum.
- The patient experienced dramatic improvement in choreiform movements within 48 hours post-surgery.
Implications:
- Pallidotomy is a viable surgical option for refractory choreiform movements secondary to cryptococcal meningitis.
- This case highlights the importance of considering surgical interventions for severe movement disorders unresponsive to medical management.
- Stereotactic pallidotomy offers a potential solution for debilitating chorea in infectious neurological conditions.
