Radio-Opacities of the Cervical Region on Panoramic Radiographs: Report of 3 Cases

Objectives: The objective of this case report was to determine radioopacities of the cervical region on panoramic radiographs using doppler ultrasound. Methods: 3 patients with radio-opacities of the cervical region on digital panoramic radiographs were referred to doppler ultrasound for further diagnosis. Results: In 2 cases carotid artery calcifications were identified as an irregular radio-opaque mass on panoramic radiographs. The calcifications in the third case were diagnosed as calcified lymph nodes due to a previous cervical abscess. Conclusions: Calcifications detected by panoramic radiographs may be due to the carotid arteries and various anatomic structures like the hyoid bone, cervical lymph nodes, epiglottis, stylohyoid ligament etc. In the present report, calcifications in the carotid arteries should be distinguished from other radio-opacities in this area as they may be an early sign of cardiovascular diseases.
