摘要
目的:分析股骨上段动脉瘤样骨囊肿的影像诊断及鉴别诊断。方法:回顾性分析46例通过手术病理证实的动脉瘤样骨囊肿患者的术前数字X线摄影(DR)、X射线计算机断层成像(CT)及磁共振成像(MRI)的影像表现,得出该病的特异性影像学表现。结果:1CT平扫显示股骨上段不规则状膨胀性骨质透亮影,其内可见多少不一、粗细不均的骨嵴或分隔,部分病变周边可见完整或不完整的骨质硬化边,部分病变突向邻近软组织内,其中8例病变内可见液-液平面,增强后可见边缘及分隔的强度强化;2MRI平扫显示大部分病变呈长T_1和长T_2信号影,周边可见长T_1和短T_2信号影,病变内可见分隔,其中8例病变内可见液-液平面影像,部分病变突向邻近软组织内,增强后可见边缘及分隔强度强化。结论:结合X射线、CT及MRI检查,可以提高动脉瘤样骨囊肿的特异性及诊断准确性,有助于与股骨上段其余骨肿瘤的鉴别诊断。
Objective: To analyze imaging diagnosis and differential diagnosis of upper femur aneurysmal bone cyst. Methods: The pre-operation imaging appearances about digital radiography(DR), computerized tomography (CT) and magnetic resonance imaging (MRI) of 46 aneurysmal bone cyst cases confirmed by operation and pathology were retrospectively analyzed, and then these special imaging appearances were gained and analyzed. Results: ①CT plain scans showed the irregular expansile lucency shadow in the upper femur with the uneven bone septum image; the complete or incomplete osteosclerosis edge can be found in some parts of lesions; some lesions extend to adjacent soft tissue, and the liquid-liquid levelcan be found in lesion of 8 cases, and their edge and separated intensity strengthening were visible after signals were enhanced.②MRI plain scans revealed that most lesions showed long T1, T2 signals, the periphery of lesions showed longT1, short T2 signal shadows, and septum image was visible within lesions, and the liquid-liquid level can be found inlesion of 8 cases; some lesions extend to adjacent soft tissue, and their edge and separated intensity strengthening were visible after signals were enhanced. Conclusion: Through combined examination of DR, CT and MRI, the specialty and diagnostic accuracy of aneurysmal bone cyst could be improved, and it was helpful in the differential diagnosis of other upper femur bone tumors.
