Abstract
BACKGROUND AND OVERVIEW: Cone-beam computerized tomographic (CBCT) imaging is increasingly used in the maxillofacial region for various purposes. The volumetric dataset created by means of CBCT increases the possibility of detecting incidental findings.
CASE DESCRIPTION: In this case report, the authors describe an otherwise healthy 45-year-old man who was referred from the Sjogren's Syndrome Center in Jerusalem, Israel, for bilateral parotid CBCT sialographic imaging owing to xerostomia lasting for 4 months. CBCT sialographic imaging using iodine contrast material showed normal glandular structure and activity according to the postcannulation panoramic imaging. CBCT sialographic imaging routine volume interpretation revealed a lesion in the mandibular area causing destruction and perforation of the cortical plates, partial disappearance of adjacent lamina dura, and resorption of adjacent teeth, suggesting an aggressive benign tumor. Histopathologic examination confirmed mural cystic ameloblastoma, which was resected with preservation of the mental nerve and the lower mandibular border. The patient received bone graft and implants, with regular follow-ups and no recurrence after 4 years.
CONCLUSIONS AND PRACTICAL IMPLICATIONS: This case strengthens the need for thorough examination of the whole CBCT imaging volume within and outside the region of interest to detect incidental findings with clinical importance.
