2例骨髓瘤表现为椎体及附件膨胀性溶骨破坏，骨皮质完整或破坏。
影像上表现为囊状、膨胀性透亮影，伴有硬化边，皮质可以保留。
由于其膨胀性生长的特性，确诊粘液囊肿是非常重要的。
1·Imaging shows a lytic, lucent, expansile lesion with sclerotic margins that spares cortex.
影像上表现为囊状、膨胀性透亮影，伴有硬化边，皮质可以保留。
2·Aneurysmal bones cysts are expansile, osteolytic lesions of bone containing thin-walled, blood-filled cystic cavities. They are named for the radiographic appearance.
动脉瘤样骨囊肿是膨胀性、薄壁溶骨性病变，其内充填以血液，因其放射学改变而命名。
3·They have well defined borders without sclerosis. They can have expansile remodeling and septations.
边界清晰，无硬化边，呈膨胀性生长，有分隔。
4·Osseous EH typically has a lytic bubbly appearance often associated with expansile bony remodeling. There may be cortical break-through or surrounding sclerosis.
典型的骨eh表现为囊性的多泡状改变，常常伴有膨胀性骨质重建，皮质可以被穿破或环绕以硬化边。
5·Mucoceles are important diagnoses to make due to their expansile nature.
由于其膨胀性生长的特性，确诊粘液囊肿是非常重要的。
