An aneurysmal bone cyst is an expansile osteolytic lesion with a thin wall, containing blood-filled cystic cavities. The term aneurysmal is derived from its radiographic appearance. The clinical manifestation depends on the specific site of involvement. A common presentation includes pain of relatively acute onset that rapidly increases in severity over 6-12 weeks.The accuracy of radiography is high, especially with lesions in the appendicular skeleton. Cross-sectional imaging may be useful in defining the extent of spinal, thoracic cage, and pelvic bone involvement. Cross-sectional imaging may not increase the specificity to a large extent.
Differential includes brown tumors in hyperparathyroidism, expansile metastasis from renal cell carcinoma and thyroid carcinoma, hemophilic pseudotumor with hemorrhage,
infestation of bone by a hydatid cyst and telangiectatic osteosarcoma
