Pseudocyst of the maxillary sinus.
A case report is presented involving the endodontic retreatment of a maxillary second molar associated with a sinus radiopacity. Disappearance of sinus pathosis occurred within 6 days after root canal debridement. A direct relationship between apical pathosis and a pseudocyst of the maxillary sinus is suggested. Thirteen-month recall shows no recurrence.
