Case Studies
Explore some diagnostic radiology findings that were identified on routine CBCT scans. Each case emphasizes radiological observations that influence diagnosis, treatment planning and referral recommendations.
Study 1
Finding: Circumferential radiodensities within the soft tissues posterior to anterior arch of atlas representing vertebral artery calcification.
Study 2
Finding: A low-density, destructive bony lesion is associated with endodontically treated tooth #30 and has eroded the adjacent buccal cortex. Codman triangle is evident at the buccal cortex, and the surrounding trabeculation appears sclerotic. These imaging findings are suggestive of a chronic inflammatory process or malignancy.
Study 3
Finding: There is an osteolytic lesion involving the right mandibular arch, characterized by effacement and expansion of the buccal and lingual cortices. Notably, there is destruction of the alveolar crest, and the cortical boundaries of the mandibular canal are eroded. These imaging findings are highly suggestive of a malignant lesion.
Study 4
Finding: A mixed-density lesion is observed at the mandibular arch, characterized by varying levels of internal radiodensity surrounded by regions of low-density. The lesion has caused expansion and resorption of the adjacent cortical plates. No root resorption is detected in the associated teeth. These imaging findings are indicative of florid cemento-osseous dysplasia.
