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

Aetiology

Odontogenic

periapical (radicular) cyst (60% of odontogenic cystic lesions ⁴)
periapical abscess
dentigerous (follicular) cyst
odontogenic keratocyst (keratocystic odontic tumour)
ameloblastoma
primordial cyst of the jaw
residual cyst of the jaw
cystic odontoma

Non-odontogenic

Langerhans cell histiocytosis

Gorham disease
