Sclerotherapy and Bone Marrow Injection In Aneurysmal Bone Cyst

Plain-language summary

Aneurysmal bone cysts (ABCs) are benign, locally destructive growing bone tumors, which were first described in 1942 by Jaffé and Lichtenstein (1). They are most often diagnosed in childhood and early adulthood. The literature reports that ABCs comprise 1-6% of all primary benign bone tumors (2). Most cases of ABCs (75-90%) are reported for patients younger than 20 years, with a slightly higher incidence for females (3). Most common localizations are the pelvis, the metaphysis of long bones and the spine, but ABCs can also affect any other localization(2). ABCs that are associated with a preexisting osseous lesion are defined as secondary ABCs. They represent approximately 30% of all ABCs (2). Secondary ABCs can occur, e.g., in cases of a giant cell tumor, chondroblastoma or telangiectatic osteosarcoma
