The nasopalatine duct cyst is characterized radiographically by an ovoid radiolucency, which can sometimes appear heart-shaped due to the anatomical structures surrounding it, particularly the incisive papilla and the shape of the anterior maxilla. This cyst typically occurs in the midline of the anterior maxilla, between the central incisors, and is the most common non-odontogenic cyst of the oral cavity.

The ovoid shape is a result of the cyst's location and the space it occupies in the bone. The heart-shaped appearance can occur if the cyst is superiorly positioned in relation to the incisive papilla, particularly if it is somewhat elongated or if the surrounding bony contour creates that visual effect. This feature is essential in distinguishing it from other types of cysts and lesions.

Recognizing the characteristic appearance of the nasopalatine duct cyst on radiographs is crucial for diagnosis and management in dental practice.
