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.

They found p63 overexpression in roughly 30% of chondroblastomas and aneurysmal bone cysts, but not in giant cell reparative granulomas, pigmented villonodular synovitides, or tenosynovial giant cell tumors.
The 2 previous studies did not show evidence of p63 overexpression in cases of tenosynovial giant cell tumors, giant cell reparative granulomas, or pigmented villonodular synovitides, and the degree of p63 expression in aneurysmal bone cysts and chondroblastomas was significantly lower.
Because osteoblastoma can be very hemorrhagic and show secondary aneurysmal bone cyst changes, and conversely, because primary aneurysmal bone cyst can show extensive reactive new bone production that resembles osteoblastoma, it can be challenging to tell them apart in some cases.
Giant cell tumor, however, can show a variety of secondary histologic changes including osteoid and woven bone formation and secondary aneurysmal bone cyst changes that mimic osteoblastoma.
Aneurysmal bone cyst is rare in extraskeletal locations, especially if compared to the incidence of other proliferative lesions of chondro-osteoid lineage that can occur outside bones.
Aneurysmal bone cyst should be considered in the differential diagnosis of a laryngeal lesion containing giant cells.
Likewise, EG, chondroblastoma, solitary and aneurysmal bone cysts are rarely seen in adults >30 yrs.
There is low signal on T1 and variable T2 MRI signal, which may include hyperintense regions or fluid levels secondary to aneurysmal bone cysts.
