Background: Orbital cholesterol granuloma is a rare but well-defined entity that occurs due to a foreign body reaction with cholesterol crystals, predominantly involving the diploe of the frontal bone, and usually presenting in the superolateral orbit. Its pathogenesis is unclear; however, it is usually seen in young to middle-aged males with history of trauma.
Case presentation: This study presents a 50-year-old male who presented with a superolateral orbital mass that was diagnosed as cholesterol granuloma after excision biopsy. The patient was operated and the lesion was excised through anterolateral orbitotomy via a sub-brow skin incision with dissection of the soft tissue until reaching the mass. Curettage of the affected bony surface was also carried out. The patient was then discharged.
Conclusion: Ophthalmologists and otolaryngologists should be aware that cholesterol granulomas might be presented as orbital mass lesions in patients with a history of sinusitis or sinus surgery.
