Background Although osteoma is a common benign tumor of the paranasal sinuses, its orbital extension is not common. Secondary orbital cellulitis has rarely been reported in association with sino‐orbital osteoma. Case A 30‐year‐old woman presented with left side proptosis, orbital pain and inflammation. Orbital CT scan showed a well‐defined giant osteoma in the superonasal part of the left orbit originating from the left ethmoidal sinus associated with opacity of the ipsilateral ethmoidal sinus and infiltration of orbital soft tissue. After treatment by systemic antibiotics, osteoma was resected with combined external and endoscopic surgery and the patient recovered uneventfully. Conclusion Sino‐orbital osteoma may manifest primarily as orbital cellulitis and needs early surgical intervention.
