Common lesions which show multilocular radiolucency are:
- Ameloblastoma
- Odontogenic keratocyst
- Odontogenic Myxoma
- Central Giant Cell Granuloma
- Central Hemangioma
- Aneurysmal bone cyst
- Cherubism
1. Ameloblastoma
- Soap bubble or honeycombed appearance
- Most common in 3rd molar- ramus area
- Notching is seen in advancing end of tumor
- Root resorption and displacement of adjacent teeth is seen
- Rarely causes perforation
2. Odontogenic Keratocyst
- Soap bubble appearance
- No expansion of cortical plates, because the lesion grows anteroposteriorly
3. Odontogenic myxoma
- Exclusively seen in Jaws, only in tooth-bearing portions
- angular or tennis racket or honeycomb appearance
- May be found in association with an impacted tooth
4. Central giant cell granuloma
- It is a reactive process, but not a neoplasm
- Soap bubble or honeycomb appearance
- a characteristic feature is that the septa are perpendicular to the periphery of the lesion and notching is seen corresponding to outline where septa arise.
5. Central hemangioma
- soap bubble appearance
- Swelling of Jaws, gingival bleeding through sulcus is seen
- " Pumping action " is a characteristic clinical feature. If tooth in the region of the tumor is pushed into the tumor, it will be rebound back to the original.
6. Aneurysmal bone cyst
- history of trauma, the cyst is reactive process secondary to trauma
- honeycomb or soap bubble appearance
- frank blood on aspiration
- pseudocyst
- multinucleated giant cells are seen histologically
7. Cherubism
- seen at 2-6 years of age with a familial history
- When maxilla is involved, the skin over it is stretched with pulling of skin below eyes. The sclera is visible giving "angelic look" or "eyes towards heaven".
- Multiple unerupted teeth are seen which appear to be floating in cyst-like spaces.
