Summary
A middle cerebral artery aneurysm can cause isolated hyperacusis, a rare symptom. Coil embolization resolved the patient's symptoms, suggesting further investigation for such cases.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Neurology
Background:
- Cerebral aneurysms are abnormal bulges in brain arteries.
- Hyperacusis is an increased sensitivity to everyday sounds.
- Aneurysms rarely present with neurological symptoms other than those directly related to rupture.
Observation:
- A patient presented with isolated hyperacusis as the sole symptom.
- Neuroimaging revealed an unruptured middle cerebral artery aneurysm.
Findings:
- The patient underwent Guglielmi detachable coil (GDC) embolization for the aneurysm.
- Successful GDC embolization led to complete resolution of hyperacusis.
Implications:
- This case highlights a potential, albeit rare, presentation of cerebral aneurysms.
- Suggests considering radiological investigations for young patients with unexplained hyperacusis.
- Further research into the pathophysiological link between aneurysms and hyperacusis is warranted.
