Abstract
Tumoural and cystic lesions are common findings in the daily practice of dental professionals and maxillofacial radiologists. However, simultaneous lesions are rare and represent a diagnostic challenge to overcome. Among tumoural pathologies, odontomas are the most common odontogenic tumour of the jaws. Cystic transformation or development from the tumoural capsule are well recognized in situations such as ameloblastomas originated from a dentigerous cyst. Otherwise, despite literature reports, dentigerous cysts arising from odontomas are very rare and could lead to misdiagnosis. Here, we report a case of a complex odontoma associated with a dentigerous cyst in the maxillary sinus, focussing on the tomographic features and a differential imaging approach to the diagnosis of these lesions.
