Summary
Sudden vertigo in a 65-year-old woman was linked to a left parietal lobe infarction. This finding suggests cortical lesions can cause acute vertigo, even without typical vestibular system involvement.
Area of Science:
- Neurology
- Neuroscience
- Vascular Neurology
Background:
- Vertigo is a common symptom with diverse etiologies.
- Parietal lobe lesions are not typically associated with vertigo.
Observation:
- A 65-year-old woman presented with acute, positional vertigo and horizontal nystagmus.
- Magnetic Resonance Imaging (MRI) revealed a left parietal lobe infarction affecting the supramarginal gyrus.
Findings:
- The patient's vertigo resolved spontaneously within days.
- A transient recurrence of vertigo occurred, but repeat MRI and electroencephalogram (EEG) showed no new lesions or abnormalities.
Implications:
- This case suggests that parietal cortical infarction can be a cause of acute vertigo.
- It highlights the importance of considering central nervous system lesions in vertigo evaluation.
- Further research may elucidate the mechanisms linking parietal cortex dysfunction to vestibular symptoms.
