Nasopalatine duct cyst.Nasopalatine duct cysts are the most corm-non nonodontogenic developmental cysts originating in the incisive canal of the maxillae.(1) These cysts were once formally classified as and called fissural cysts. They were believed to originate in entrapped epithelium in embryonic fissures during the development of the orofacial region. (1) The pathogcnesis is now believed to arise from remnants of the embryonic nasopalatine duct. (2) The case presented here is that of a 50-year-old woman who had a nasopalatine duct cyst cyst, abnormal sac in the body, filled with a fluid or semisolid and enclosed in a membrane. Cysts can be congenital but are usually acquired, the most common locations being the skin and the ovaries. that had been incidentally discovered in the anterior nasopalatine area on computed tomography (CT) (figure 1) and magnetic resonance imaging magnetic resonance imaging (MRI), noninvasive diagnostic technique that uses nuclear magnetic resonance to produce cross-sectional images of organs and other internal body structures.

[FIGURE 1 & 2 OMIITED] A nasopalatine duct cyst can arise at any age, but it is seen most often in patients between 30 and 60 years of age. There is no gender predilection. These cysts are usually asymptomatic; on occasion, they present as a palatal pal·a·tal adj. Palatine. palatal (pal´  t soft-tissue mass.

On MRI, the cyst is identified as a high-intensity, well-marginated lesion in most sequences, which indicates that it contains proteinaceous material. These cysts vary in size; most are less than 2 cm, while others are large enough to cause nasal obstruction. (3) References (1.) Caruso PA, Rincon S, Weber AL.
