Atypical CT Findings in Plexiform Ameloblastoma

Ameloblastoma is an uncommon epithelial odontogenic neoplasm that is nonmineralized, locally aggressive, and, in most cases, benign. Most ameloblastomas develop in the molar-ramus region of the mandible with 70% of them arising in the molar-ramus area. Radiologically they are unilocular or multilocular radiolucency with a honeycomb or soap bubble appearance. The radiographic appearance of ameloblastoma can vary according to the type of tumor. CT is usually helpful in determining the contours of the lesion, its contents, and its extension into soft and hard tissues. Through this case we would bring to light some of the unusual CT findings which include the destruction of the surrounding structures by the lesion which appeared to be normal routine lesion when viewed clinically
