Summary
Lateral inferior pontine infarction is rare. This study presents two cases, highlighting diverse presentations and potential mimicry of labyrinthine lesions, emphasizing the importance of advanced imaging for diagnosis.
Area of Science:
- Neurology
- Neuroimaging
- Cerebrovascular Diseases
Background:
- Lateral inferior pontine infarction is an uncommon cerebrovascular event.
- Understanding its diverse clinical and radiological manifestations is crucial for accurate diagnosis.
Observation:
- Two rare cases of lateral inferior pontine infarction were analyzed.
- Magnetic resonance imaging (MRI) provided detailed correlations for both cases.
- Case presentations included involvement of the entire territory or the tegmental area, with additional involvement of the middle cerebellar peduncle and cerebellum in one case.
Findings:
- One case presented with a classical alternate syndrome.
- The second case demonstrated acute vertigo, mimicking a labyrinthine lesion due to anterior inferior cerebellar artery territory involvement.
Implications:
- These findings underscore the variability in clinical presentation of lateral inferior pontine infarction.
- Accurate diagnosis relies on detailed neuroimaging, particularly MRI.
- Recognition of atypical symptoms like vertigo is essential to avoid misdiagnosis and ensure timely intervention.
