2024年6月9日 · Aneurysmal Bone Cysts are benign, non-neoplastic, reactive bone lesions that most commonly occur in the femur and tibia. The condition typically presents in patients less than 20 years of age with focal pain and swelling.

Aneurysmal bone cysts are rare skeletal tumors that most commonly occur in the first two decades of life. They primarily develop about the knee but may arise in any portion of the axial or appendicular skeleton. Pathogenesis of these tumors remains controversial and may be vascular, traumatic, or genetic.

The classic aneurysmal bone cyst (ABC) is an expansive and hemorrhagic tumor, usually showing characteristic translocation. About 30% of ABCs are secondary, without translocation; they occur in reaction to another, usually benign, bone lesion.

We have reviewed a series of 150 aneurysmal bone cysts treated over the last 20 years. The lesions were principally located in the tibia, femur, pelvis, humerus, and spine and, in most cases, presented the imaging appearance originally described by Jaffe and Lichtenstein as a blowout with thin cortices.

2023年8月14日 · Aneurysmal bone cysts are non-malignant, tumor-like, vascular lesions that can grow aggressively, be locally destructive, and weaken bones to the point of pathologic fracture. They are more common in pediatric patients and can cause significant morbidity, especially if they involve the growth plate of bones.

Aneurysmal bone cyst is a benign, locally destruc-tive lesion of bone that was first described as a distinct entity by Jaffe and Lichtenstein9 in 1942. Mirra stated that this lesion accounted for approximately 1 percent of all bone tumors that were biopsied (no numbers were given)14.

Aneurysmal bone cysts (ABCs) are benign (not cancerous) lesions in bone, also called benign bone tumors. Although ABCs are not cancer, they can be very destructive to bone and cause pain or pathologic fractures (breaks in the bone caused by a disease rather than an injury).

Aneurysmal bone cyst (ABC) is a benign but locally aggressive lesion that predominantly affects children and young adults. ABC, which accounts for approximately 70% of the cases, is now recognized to be a true neoplasm, whereas ABC-like changes ...

Aneurysmal bone cysts are aggressive benign lesions with high rates of recurrence rendering its treatment uniquely challenging. The standard of treatment remains curettage and grafting to fill the bone void, but the adjuvant or alternative treatment methods to …

2024年11月14日 · Aneurysmal bone cysts (ABC) are benign expansile osteoclastic giant cell-rich bony neoplasms, composed of numerous blood-filled channels and cystic spaces 1. ABC accounts for the 'A' in the popular mnemonic for lucent bone lesions FEGNOMASHIC.
