Abstract:
A study was conducted to evaluate CT imaging in differentiating nonodontogenic nasopalatine duct cysts from odontogenic radicular cysts. The patient's palatine cystic lesion was analyzed by CT and excised with postoperative microscopic identification. CT findings of a nasopalatine cyst are midline location, smooth expansion with sclerotic margins and displacement of teeth apices. Radicular cysts differ in that the teeth apices are within the cyst rather than being displaced. We concluded that differentiation is clearly demonstrated by CT images.
