Terms in this set (44)
Thin and well demarcated RADIOPAQUE rim of bone at the periphery
Corticated borders
Benign slow-growing
Fuzzy and ill defined (irregular) WITHOUT a thin radiopaque rim at the periphery
Non corticated borders
Malignant or Benign
Exhibits a thin, well demarcated radiopaque rim of bone at the periphery
Unilocular radiolucent lesion Usually indicative of of a benign, slow-growing process
One small space/ compartment
TCDHA Radiology Midterm-Final Review
1/5
, - possess multiple radiolucent compartments
- larger than a unilocular lesion
- exhibits well-defined and corticated margns
- lesions are expansile and tend to displace the buccal and lingual bone plates
Multilocular radiolucent lesions
- benign with aggressive growth potential
AKA soap bubbles
Eg. Odontogenic, keratocyst, ameloblastoma
Eg. Cherubism; aka : chubby cheeks
Multi-focal
( mixed w radiopaque components)
- exhibits both radiopacity and radiolucency
- appear as a radiolucent area w/ central opaque flecks or calcification
Mixed lucent-opaque
Eg. Compound odontoma
Multiple radiopacities that appear to overlap or flow together. Involving multiple quadrants of
the jaw usually represent benign fibro-osseous disorders
Multi-focal confluent
Eg. Osteitis deformans (pagets disease)
Lesion located around the apex of the tooth
Periapical location
Eg. Periapical cyst
Lesion b/w the roots of adjacent teeth
Inter radicular lesion
Eg. Lateral periodontal cyst
A lesion located in an area without teeth. A variety of radiolucent lesions may occur in this
Edentulous zone
zone
A lesion located around the crown of an impacted tooth
Pericoronal lesion
Eg. Dentigerious/ follicular cyst
Irregular ill defined radiolucent borders as well with mixed ill defined radiopaque pattern
areas
Moth eaten pattern
May represent a malignant condition ie. Osteosarcoma and chondrosarcoma
SLOB Same direction - lingual; opposite direction = buccal
