Bilateral nasolabial cysts: a case report

View Article: PubMed Central - PubMed

ABSTRACT

Background: Nasoalveolar cysts are rare non-odontogenic cysts that occur beneath the nasal alar region. Few cases of bilateral nasoalveolar cysts have been described.

Case presentation: We report a rare case of a 67-year-old Japanese woman with bilateral nasoalveolar cysts who presented to our department with the chief complaint of a swollen left nasal alar base. Panoramic radiography revealed no abnormalities. Computed tomography and magnetic resonance imaging revealed a well-circumscribed oval lesion at both alar bases. Therefore, bilateral nasoalveolar cysts were clinically diagnosed. Furthermore, these cysts were extirpated under general anesthesia; the aforementioned diagnosis was histopathologically confirmed. No recurrence has been observed 1 year after surgery.

Conclusions: Nasoalveolar cysts are rare. It is necessary to be careful because nasoalveolar cysts can show bilateral occurrence.

No MeSH data available.


Computed tomography image obtained at the first examination. A well-circumscribed oval lesion, approximately 19 × 14 × 12 mm in size, was found inferior to the left nasal alar base. A small high-density area was observed adjacent to the right piriform aperture

Fig3: Computed tomography image obtained at the first examination. A well-circumscribed oval lesion, approximately 19 × 14 × 12 mm in size, was found inferior to the left nasal alar base. A small high-density area was observed adjacent to the right piriform aperture

Mentions: A panoramic radiograph showed no abnormal findings (Fig. 2); however, apical periodontitis of her left upper central incisor was observed. Computed tomography (CT) findings revealed a well-circumscribed oval lesion, approximately 19×14×12 mm in size, inferior to her left nasal alar base (Fig. 3). The lesion was relatively homogeneous and showed a lower density than the muscle. Absorption of the maxilla and nasal septum was not clearly identifiable on the CT images. Although an area of high density was observed adjacent to the right piriform aperture, it was difficult to confirm the presence of a lesion.Fig. 3
