A 17-Year-Old Girl With Unilateral Headache and Double Vision

Area of Science:

• Neuro-ophthalmology
• Pediatric Neurology
• Radiology

Background:

• Tolosa-Hunt syndrome (THS) is a rare condition causing painful ophthalmoplegia due to granulomatous inflammation affecting the cavernous sinus or orbital apex.
• Clinical presentation includes painful ophthalmoplegia with potential involvement of cranial nerves II-VI.
• Magnetic resonance imaging (MRI) is key, revealing characteristic enhancement of the cavernous sinus and/or orbital apex.

Observation:

• THS is exceptionally rare in pediatric populations.
• A case of a pediatric patient with neurological symptoms and a unilateral cavernous sinus MRI abnormality is presented.
• The diagnostic process for this rare pediatric presentation is detailed.

Findings:

• The study highlights the diagnostic challenge of THS in children, emphasizing its rarity.
• Differential diagnoses for unilateral cavernous sinus lesions are extensive, including vascular, inflammatory, neoplastic, and infectious causes.
• The described case underscores the importance of considering THS in the pediatric differential diagnosis.

Implications:

• This case report emphasizes the need for a high index of suspicion for Tolosa-Hunt syndrome in children presenting with painful ophthalmoplegia.
• Accurate and timely diagnosis is critical for appropriate management and to differentiate from other serious cavernous sinus pathologies.
• The findings contribute to the understanding of THS in pediatric neurology and neuro-ophthalmology, guiding diagnostic strategies.
