| Popis: | CLINICAL PRESENTATION An 18-year-old woman was referred to the maxillofacial outpatient clinic by a dentist owing to a radiolucent lesion discovered incidentally on a routine panoramic radiograph. The oral examination found swelling at the area of the left maxillary premolars. The swelling was bony-hard, nontender, and approximately 1 cm in size, and the overlying mucosa was normal. The adjacent teeth tested vital, and no evidence of periodontal disease or caries was detected. There was no tooth mobility, and the occlusion remained unchanged. The patient was asymptomatic, was otherwise healthy, and reported a noncontributory medical and dental history. No history of trauma was recorded. The panoramic radiograph of the patient showed a wellcircumscribed, unilocular, radiolucent lesion, interspersed with opaque formations, at the area of the left maxillary premolars (Figure 1). The unusual opacity in the area of the maxillary midline was a piece of nose-piercing jewelry. The lesion was further investigated with a computed tomography (CT) scan, which found a well-demarcated lesion, measuring 3 2.8 2.5 cm. The lesion had caused expansion of the buccal cortex, in conjunction with elevation of the floor of the maxillary sinus. No bony erosion was identified. The lesion was not homogeneous, with an average density of 190 Hounsfield units, and also contained multiple hyperdense spots, representing calcified structures (Figure 2). |
