Masses of
developmental and genetic origin affecting the paediatric craniofacial skeleton. Typical manifestations of nevoid basal cell carcinoma syndrome (NBCCS) in a 16-year-old boy. a Orthopantomography (OPT) shows cystic lesions of the mandible and maxilla (arrows), with unilocular and multilocular pattern and smooth or scalloped borders associated with displaced and unerupted permanent teeth. b Coronal CT scan (bone window) shows ectopic calcifications of the falx cerebri and tentorium cerebelli (arrows) and spotted meningeal calcifications (arrowheads). Brain MRI reveals a cavum veli interpositi on axial T2 (asterisk in c) and coronal contrast-enhanced T1 (asterisk in d) and also vermian dysgenesis (arrowheads in d)
Mandibular
Ameloblastoma. A) Hypodense lesion in the mandibular body with cortical thining (arrows). B) A cystic extension/loculation is visible anteriorly to the right portion of the mandibular body, causing cortical bone disruption (thick arrow).
Mandibular
Ameloblastoma. A) and B) The cystic extension/loculation is visible anteriorly to the right mandibular body, showing an anterior enhancing septum (arrows).
Mandibular
Ameloblastoma. Large bubbly lucent lesion in the mandibular body (arrows).

Lucent lesions of the mandible are not uncommon and may be the result of odontogenic or non-odontogenic processes. Lucency may be conferred by a cystic process (e.g. periapical cyst) or a lytic process (e.g. mandibular metastases).
Pathology
Etiology
Odontogenic
- periapical (radicular) cyst (60% of odontogenic cystic lesions )
- periapical abscess
- dentigerous (follicular) cyst
- odontogenic keratocyst (keratocystic odontic tumor)
- ameloblastoma
- primordial cyst of the jaw
- residual cyst of the jaw
- cystic odontoma
Non-odontogenic
- fibrous dysplasia/cherubism
- mandibular metastases
- squamous cell carcinoma invading mandible
- multiple myeloma
- giant cell granuloma
- aneurysmal bone cyst
- peripheral nerve sheath tumor of mandible
- traumatic bone cyst of jaw (simple cyst)
- Stafne cyst
- brown tumor
- Langerhans cell histiocytosis
- Gorham disease
