Megadolichobasilar anomaly can cause serious neurological issues. A patient with this condition and a basilar artery aneurysm experienced vertigo and deafness due to blocked blood flow, with deafness being permanent.
Area of Science:
- Vascular Neurology
- Neuro-otology
Background:
- Megadolichobasilar anomaly is a basilar artery dilation linked to hypertension.
- It can lead to cerebellopontine angle syndromes or vertebrobasilar infarcts.
Observation:
- A patient with megadolichobasilar anomaly and a partially thrombosed fusiform basilar artery aneurysm presented with sudden vertigo.
- This was followed by hearing loss attributed to thromboembolic occlusion of the labyrinthine artery.
Findings:
- The patient's vertigo resolved over time, consistent with a vascular etiology.
- However, the deafness resulting from labyrinthine artery occlusion persisted.
Implications:
- This case highlights the potential for complex vascular events in megadolichobasilar anomaly.
- It underscores the varied and sometimes permanent neurological deficits that can arise from basilar artery pathology.
