Acquired Brown's syndrome: an unusual cause

Area of Science:

• Ophthalmology
• Oncology

Background:

• Brown's syndrome is a rare condition characterized by mechanical restriction of the superior oblique muscle.
• Acquired Brown's syndrome can result from various orbital pathologies.

Observation:

• A 62-year-old male presented with symptoms consistent with acquired Brown's syndrome.
• Imaging revealed an orbital metastatic deposit as the underlying cause.

Findings:

• Orbital metastasis is identified as a novel cause of acquired Brown's syndrome.
• The case highlights the importance of considering metastatic disease in the differential diagnosis.

Implications:

• This finding expands the known etiologies of acquired Brown's syndrome.
• Early diagnosis and management of orbital metastases can prevent vision-threatening complications.
