Diagnosis of mucosal cyst in the maxillary sinus using advanced MR imaging techniques: Report of a case

In the present study, new MRI techniques were used to evaluated the pathologic condition of a mucosal cyst in the maxillary sinus. The contrast enhancement technique using Gd-DTPA clearly revealed the cystic nature of the lesion. The diagnostic information about the relationship between the mucosal cyst and periodontal disease, and the precise location of the cyst in relation to the walls of the maxillary sinus were obtained by panoramic MR image and alternate positioning of the patient.
