Antrochoanal polyps arise from the musosa of maxillary sinus and then extend into the nasal cavity and the choana. These are more common in children. It most commonly originates from the posterolateral wall of the maxillary antrum and passes into the middle meatus through the natural maxillary ostium or occasionally through an accessory maxillary ostium. Although there are many documented cases of polyps exiting the maxillary sinus through the accessory ostium, only three cases have been reported as exiting specifically through the anterior fontanelle. We are hereby presenting such a case antrochoanal polyp exiting through the anterior fontanelle which is very rare presentation of these polyps.
