A case of concurrent silent sinus syndrome, thyroid eye disease, idiopathic orbital inflammatory syndrome, and dacryoadenitis.

This is a retrospective case description of a single female patient found to have concomitant bilateral silent sinus syndrome, bilateral thyroid eye disease, unilateral dacryoadenitis, and idiopathic orbital inflammation that presented as progressive unilateral right-sided proptosis. The spectrum of inflammatory orbital diseases can make discerning between different entities challenging, but more unique in this case was the simultaneous presentation with bilateral silent sinus syndrome, a rare entity in its own right. Identifying each of these concurrent disease processes is important to establishing a multidisciplinary treatment approach to address all the patient's orbital and peri-orbital pathology. We hope to highlight the clinical and radiographic findings unique to each of these entities and share our approach to treatment in this complex case.
