Idiopathic Granulomatous Orbital Inflammation with Right Frontal Nerve Involvement: A Case Report

Abstract

Introduction: Idiopathic granulomatous orbital inflammation is a rare subtype of orbital inflammatory disease, and frontal nerve involvement has not been previously described. Case Presentation: This is a case of a 75-year-old female who presented with a 4-week history of a right orbital mass, scalp dysaesthesia, and ptosis. Magnetic resonance imaging of the orbits confirmed a right supraorbital mass originating from the lacrimal gland with frontal nerve enlargement. Biopsy showed non-caseating granulomatous inflammation. Conclusion: The patient was treated with an intralesional triamcinolone injection and oral prednisolone and will continue to be monitored for development of systemic sarcoidosis.
