Case in brief
A 6-year-old child presented with vision loss and was found to have a sizable soft-tissue mass in the left pterygopalatine fossa extending into the inferior orbital fissure. The mass was removed endoscopically through an intranasal prelacrimal recess approach. Postoperative pathology confirmed a schwannoma, and the report describes the removal as successful.
What made this case unusual
The schwannoma arose in the pterygopalatine fossa of a child and presented with vision loss; both the site and pediatric presentation are described as particularly uncommon.
Diagnostic / clinical pearl
A pterygopalatine fossa mass extending into the inferior orbital fissure can present with vision loss; pathology confirmed schwannoma in this case.
Why it matters
The report underscores the diagnostic and therapeutic challenges of pediatric pterygopalatine fossa schwannomas and the role of multidisciplinary management.
