1. Marsupialized nasolabial cyst in left anterior maxilla

A well-defined, air-filled radiolucency is present buccal to the left anterior maxillary alveolar process. A soft tissue periphery surrounds this air-filled space. The buccal surface of the underlying maxillary alveolar process has been remodeled by this air-filled defect. The location of this entity suggests this represents a nasolabial cyst, which has marsupialized and filled with air.

Axial views of left anterior maxilla

These axial cross-sectional images demonstrate the broad-based concavity along the buccal aspect of the left anterior maxillary alveolar process. This remodeling of the alveolar process is a result of a nasolabial cyst, which has marsupialized and is presently occupied by an internal air-like density surrounded by a soft tissue periphery. No communication between this collection of air and the nasal cavity is apparent at this time.

Coronal views of anterior maxilla

These coronal cross-sectional images demonstrate effacement of the left anterior nasal floor by the nasolabial cyst.

Sagittal views of left anterior maxilla

These sagittal cross-sectional images demonstrate pressure remodeling along the buccal aspect of the maxillary alveolar process adjacent to the nasolabial cyst. No signs of odontogenic pathology are present.

Normal post-treatment appearance of tooth 21

Tooth 21 appears normal radiographically. No signs of endodontic or periradicular pathology are present. The buccal cortical plate is intact. Tooth 21 is not the source of the patient's symptoms.

Axial views of tooth 21

These axial cross-sectional images demonstrate the normal appearances of the root and surrounding bone of tooth 21. No signs of root fracture are present.

Buccolingual views of tooth 21

These buccolingual cross-sectional images demonstrate the intact buccal cortical plate overlying the root of tooth 21. The apical lamina dura is also intact, and no signs of periapical pathology are present.

Mesiodistal views of tooth 21

These mesiodistal cross-sectional images demonstrate the normal appearance of the alveolar bone on the mesial and distal surfaces of the root of tooth 21. Tooth 21 is unrelated to the marsupialized nasolabial cyst.
