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

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 four-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.
