Aneurysmal bone cyst on the left zygomatic arch concomitant with bilateral inferior turbinate gasification in an adult female: A case report

Abstract

The simultaneous occurrence of an aneurysmal bone cyst (ABC) on a zygomatic arch with bilateral inferior turbinate gasification is extremely rare, and no previous studies are available. Here we report the case of a 34-year-old Chinese Han female who presented with hyperplasia of the left maxillary bone for one and a half years. The patient was observed to have an ABC on the left zygomatic arch concomitant with bilateral inferior turbinate gasification, as indicated by X-ray computed tomography, contrast-enhanced computed tomography and three-dimensional maxillofacial reconstruction. The patient underwent surgical resection of the cyst, and no postoperative symptoms were observed during the 4 years of follow-up. The etiology of this case is considered to be associated with a gene abnormality.

Keywords: aneurysmal bone cyst; inferior turbinate gasification; zygomatic arch.

Figure 1.
X-ray computed tomography images of the paranasal sinus revealed bilateral inferior turbinate gasification (green arrows) and a round, alveolate high-density cyst on the left zygomatic arch (red arrow). The cyst had a clear boundary and was close to the lateral wall of the left maxillary sinus.

Figure 2.
Contrast-enhanced computed tomography images of the paranasal sinus, revealing a round, alveolate high-density cyst on the left zygomatic arch (green arrow). There were no distinctive enhancement characteristics in either the arterial (red arrow) or venous phases (blue arrow).
Figure 3.
Figure 3.
Three-dimensional reconstruction of the left maxillary bone, demonstrating a round cyst located in the area where the left zygomatic arch intersects the maxillary bone (green arrow). The surface of the cyst was fairly smooth, and the superior wall of the left maxillary sinus was intact.

Biopsy examination of the cyst. The blood lacuna and connective tissue compartment, revealing tissue cells and osteoclastic multinuclear giant cells (black arrow). No evidence of new reactive bone formation was observed. Hematoxylin-eosin staining. Magnification, ×200.
