[Atypical Cogan's syndrome. Based on a case]

Area of Science:

• Ophthalmology
• Rheumatology
• Otorhinolaryngology

Background:

• Cogan's syndrome is a rare systemic inflammatory disorder.
• It classically presents with ocular inflammation (interstitial keratitis) and hearing loss or dizziness.
• Systemic vasculitis is a known complication.

Observation:

• This report details a 64-year-old woman with an atypical presentation of Cogan's syndrome.
• Her primary ocular manifestation was anterior uveitis, not the typical interstitial keratitis.

Findings:

• The patient's case highlights the variability in Cogan's syndrome presentations.
• Anterior uveitis can be a key ocular feature in atypical Cogan's syndrome.

Implications:

• Recognizing atypical ocular signs like anterior uveitis is crucial for diagnosing Cogan's syndrome.
• Early diagnosis and management of Cogan's syndrome can prevent severe systemic and ocular complications.
