title: [Intralingual dermoid cyst: imaging features of a giant cyst].
abstract: Dermoid cysts of the oral cavity are rare and most commonly involve the floor of mouth. Intralingual dermoid cysts are extremely rare and usually large at the time of diagnosis in adult patients. We report the case of 6 year old girl with macroglossia and swallowing and respiratory difficulties due to a giant intralingual dermoid cyst. Ultrasonography showed a large cystic intralingual lesion. MRI allowed accurate evaluation of the size, the extension and the relationship of the cystic mass with adjacent structures, the fat component of the cystic mass confirmed the dermoid origin. This case illustrates the diagnostic contribution of US and MRI in this disease.
