Can a maxillary sinus retention cyst be cancerous?
RE: Maxillary mucous retention cyst. My panoramic dental X-ray shows Lt Maxillary sinus half-size of the Rt due to some growth on the lateral side of Lt Max sinus, top to bottom. ENT Dr says it is mucous retention cyst & not treatable & was quite dismissive. My question is, due to lateral location & large size half of sinus & being unilateral, would a CT scan be in order to rule out any other diagnosis, such as cancer?
