Summary
Sudden bilateral cortical deafness is a rare stroke symptom. Prompt stroke diagnosis and treatment are crucial for this time-sensitive, potentially reversible condition.
Area of Science:
- Neurology
- Otolaryngology
Background:
- Sudden-onset bilateral cortical deafness is a rare but critical stroke symptom.
- Early recognition and intervention are vital due to the time-dependent nature of stroke treatment.
Observation:
- A 53-year-old man experienced acute, complete bilateral hearing loss that spontaneously resolved over 4 hours.
- Magnetic resonance imaging revealed a left temporoparietal ischemic lesion involving the insular cortex and a prior right temporoparietal infarction.
Findings:
- The patient's hearing loss was attributed to a stroke affecting the auditory cortex.
- Lesions in these specific brain regions may present with sensory or cognitive deficits rather than motor symptoms, complicating diagnosis.
Implications:
- Sudden bilateral deafness warrants immediate stroke evaluation, prioritizing acute revascularization therapies.
- Recognizing cortical deafness as a stroke manifestation is essential for timely and effective patient management.
