A 40-year-old man with no history of trauma or previous sinus surgery complained sudden right diplopia after vigorous sneezing. The patient was submitted elsewhere to a MRI study for persisting diplopia, with inconclusive findings. One week later the patient was submitted to a maxillofacial cone beam CT (CBCT) in our Institution. A blowout fracture of the right orbital floor and lateral orbital wall with an intact orbital rim and a ipsilateral maxillary sinus effusion with an air liquid level, were detected at the CBCT study. Our conclusion, confirmed by the clinician, was the patient had a barotraumatic, isolated, pure blowout fracture of the right orbit consequence of the episode of vigorous sneezing. The patient was treated by steroid and antibiotic therapy and diplopia resolved after two weeks. Clinicians and radiologists should be aware that a barotraumatic blowout fracture of the orbit after sneezing should be included among the unusual causes of sudden diplopia.
