Metastasen in der Mandibula
Radiolucent
lesions of the mandible: a pattern-based approach to diagnosis. Condylar metastasis from adenocarcinoma. OPT (a) with osteolytic ill-defined lesion of the mandibular condyle (arrow). b Sagittal PET/CT image shows high metabolism with SUV = 12 (arrow). c Axial, contrast-enhanced, fat-saturated T1-weighted image. The infiltrative, bulky lesion invades the condyle (arrow), the internal pterygoid muscle (dashed arrow) and part of the parotid gland (thin arrow). d Intraoperative view. Extensive condylar involvement. e Histology (haematoxylin-eosin stain, original magnification 80×): large atypical polygonal cells, some with several nuclei (arrow)

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
