An expansile lytic lesion is a type of bone lesion that may arise from numerous benign or malignant conditions, leading to the destruction of bone tissue. Bone tumors are predominantly benign. Certain bone tumors, like aneurysmal bone cysts and giant cell tumors, are more common in females, but this doesn´t significantly affect their diagnosis and treatment. Aneurysmal bone cysts, classified into primary and secondary types, are expansile lytic lesions with multiple fluid levels, often accompanied by pain and associated with underlying conditions. Epiphyseal lesion in unfused physis usually signifies chondroblastoma, while a lesion in fused physis is more likely to be a giant cell tumor.
