RESUMEN
There have been few reports about extrusion of endodontic obturation materials into the maxillary sinus and inducing fungal sinusitis. Endodontic materials and fungus balls both are seen as high attenuation in a CT scan so may be overlooked. We report such a case in which the surgeon and radiologist had missed the foreign materials on preoperative CT scans, and recognized the filling defect on the alveolar bone and a foreign body in the nasal cavity postoperatively.
