Summary
Pontine hemorrhage can rarely cause delayed trigeminal motor denervation, leading to muscle atrophy. This case highlights a rare complication following brainstem stroke.
Area of Science:
- Neurology
- Neuroscience
- Clinical Medicine
Background:
- Pontine hemorrhage is a critical neurological emergency with significant mortality and disability.
- Trigeminal denervation typically results from neoplasms or trauma, with rare occurrences post-pontine hemorrhage.
Observation:
- A patient presented with progressive atrophy of the right temporalis and masseter muscles.
- This muscle atrophy was observed one year after the initial pontine hemorrhage event.
Findings:
- The case demonstrates a rare instance of delayed trigeminal motor denervation following pontine hemorrhage.
- The study details the pathogenesis and correlates clinical, electrophysiological, and radiological findings.
Implications:
- This case expands the understanding of potential neurological sequelae of pontine hemorrhage.
- It underscores the importance of considering rare complications in the long-term management of brainstem stroke patients.
