Abstract
Introduction and importance: Aneurysmal bone cysts (ABCs) are benign, non-neoplastic cystic lesions composed of multiple
blood-filled cavities, which are separated by connective tissue septa and they constitute ~6 and 1.5% of all cases of the skull and
jaws lesions, respectively.
Case presentation: Herein, the case of an 80-year-old male with a histologically confirmed diagnosis of ABC involving the body of
the left mandible was presented. The patient underwent partial mandiblectomy after confirmation of the diagnosis using
orthopantomography, a computed tomography scan, and a tissue biopsy. The patient was free from pain after 1-year of follow-up,
and the control orthopantomography showed no evidence of recurrence. This was followed by reconstruction of the healed part of
the bone with titanium plates and a piece of bone from the lateral two-thirds of the left femur and thereafter he was cosmetically well.
Clinical discussion: Patients with ABCs present with expansile and radiolucent bone lesions, which may be associated with
displacement and loss of teeth due to alveolar bone erosion. Complete excision of the lesions is mandatory for the prevention of
recurrence and increased morbidity.
Conclusion: ABCs that involve the jaws are extremely rare and are more likely to pose a diagnostic challenge as they are more likely
to be confused clinically with other expansile radiolucent bone lesions such as ameloblastoma, osteoblastoma, and giant cell tumor
among many others. Also, those with extensive bone matrix formation may sometimes be confused histologically with other bone
forming tumors including osteosarcoma. Recurrence is common but it can be avoided or minimized by complete resection of the
lesion.
