title: Eosinophilic granuloma masquerading as fracture of the orbital roof: case report.
abstract: Orbital involvement of eosinophilic granuloma accounts for less than 1% of all orbital tumors. The most common presenting sign of eosinophilic granuloma is bilateral or unilateral proptosis; rarely, neural parenchyma involvement is observed. This article features a case report of a 16-year-old male patient who presented to the authors after minor trauma that simulated a fracture near the orbital apex. The authors conclude that the diagnosis of eosinophilic granuloma should be considered if there is unusual location of apparent "fracture," a mass in the region of the fracture, lysis of bone, and recurrence of inflammation after the initial injury has subsided. Timely intervention with appropriate excision, histologic confirmation, and reconstruction with proper follow-up are the cornerstones of therapy for this rare disorder.
