an·eu·rys·mal bone cyst

[MIM*606179]
a solitary benign osteolytic lesion expanding a long bone or within a vertebra, consisting of blood-filled spaces, and separated by fibrous tissue containing multinucleated giant cells; may cause swelling, pain, and tenderness and compromise the structural integrity of the involved bone.

aneurysmal bone cyst

a cystic lesion that tends to develop in the metaphyseal region of long bones but may occur in any bone, including a vertebra. It may produce pain and swelling and generally increases in size gradually. Skin temperature around the bone may increase. It is usually removed surgically, but radiation may be used in cases when the tumor is not readily accessible.

aneurysmal bone cyst

A tumour-like osteolytic lesion most commonly seen in patients age 10 to 20, more common in females, often located in the metaphysis of long bones, vertebrae and flat bones.

Imaging
Physaliferous (soap-bubble-like), osteolytic, eccentric expansion of bone with cortical erosion and destruction, and scant periosteal neo-osteogenesis.
 
Management
Curette bone defects, fill with bone chips.
