Review Article: Aneurysmal Bone Cysts of the Jaws

Abstract

Aneurysmal bone cyst (ABC) is a osteolytic bone lesion that rarely involves the jaws. To date, a total of 92 cases of JABCs have been described in detail in English literature. They prevalently occur in the first 2 decades (72.8%) with slight female predilection. It affects the mandible more often (68.5%) with a predominant location in the mandibular ramus (31.3%) and its posterior regions (20.4%). A painless (54.7%) or painful (43.2%) bone swelling is the most frequent clinical sign. Radiologically 93.8% of the lesions present as a radiolucency; in 69.4% multilocular in appearance. 15.2% of JABCs were secondary in nature, including 8 cases associated with fibrous dysplasia. The recurrence rate (13.3%) did not differ significantly when comparing the surgical technique (curettage, 15.2%; resection, 11.8%). JABCs are known for their different clinical and radiographic features, therefore often posing a diagnostic dilemma. Some JABC's may be secondary in nature. Careful curettage is considered to be suitable as treatment for JABCs.

Mandibular aneurysmal bone cyst in a child misdiagnosed as acute osteomyelitis: a case report and a review of the literature

“…The characteristic fluid-fluid levels may be demonstrated by both CT and MRI, with the MRI being the more sensitive procedure [1]. Although the MRI scan usually is very helpful for diagnosis, a number of osteolytic lesions must be considered as differential diagnosis including odontogenic cysts and tumors, traumatic bone cysts, and giant cell tumors, as well as other primary and metastatic tumors [15]. Therefore, definitive diagnosis requires the histopathological examination of the surgical specimen.…”

“…In some cases, localization and extend of the cysts can make resection impossible and curettage difficult due to potential hemorrhage. Thus, reported recurrence rates vary widely from 13% to 70% [5,11,15,16], depending on the location and treatment modalities. In our case, the tumor was dissected completely although the prolongated diagnostic process complicated the excision due to continuous tumor growth.…”

“…Clinical presentation ranges from small indolent to rapidly growing destructive lesions [4,15]. It was first described by Jaffé and Lichtenstein in 1942 who distinguished ABC from other cystic lesions and giant cell tumors [8].…”

Aneurysmal bone cyst of mandibular condyle: A case report and review of the literature

“…It represents about 1.5% of all nonodontogenic and non-epithelial cyst-like lesions in the jaws (Padwa et al, 1997). In the jaws, ABC affects the mandible more frequently (twice as frequently as the maxilla) and is most commonly located in the mandibular posterior ramus (Sun et al, 2009). Only rarely has involvement of the mandibular condyle been reported.…”

Cemento-Osseous Dysplasia-Like Lesion and Complex Odontoma Associated with an Impacted Third Molar

“…Association of benign fibro-osseous lesions of the jaws with simple bone cysts [4] and aneurysmal bone cysts [5,6] has been previously reported. Herein, we present a case of a benign fibro-osseous lesion consistent with COD that was located coronally to the crown of an impacted mandibular third molar, and which was also associated with a complex odontoma.…”
