目的探讨髂骨恶性骨肿瘤的临床表现及MRI在其诊断中的价值。方法回顾性分析2010年3月至2014年11月经手术病理和(或)临床随访证实的18例髂骨恶性肿瘤患者的临床及MRI影像资料。结果 20例中,骨转移瘤17例,骨肉瘤3例。转移瘤均伴骨盆等处多发病灶。本组骨肉瘤均为髂骨及周围孤立性病变、分布连续、界清而僵硬。MRI均表现为髂骨骨质破坏,呈T1WI低T2WI及抑脂序列高信号。MRI发现了7例X线阴性的髂骨早期转移性病变。结论 MRI是评价髂骨恶性骨肿瘤较佳的影像学方法。
Objective To investigate the clinical manifestations of iliac malignant bone tumor and the value of MRI in its diagnosis. Methods The clinical and MRI images of 18 patients with iliac malignancies confirmed by surgical pathology and / or clinical follow-up from March 2010 to November 2014 were retrospectively analyzed. Results Of the 20 cases, 17 were bone metastases and 3 were osteosarcomas. Metastases are associated with multiple lesions such as the pelvis. The group of osteosarcoma are isolated iliac lesions and around the distribution of continuous, clear and rigid boundaries. MRI showed the destruction of iliac bone, T1WI low T2WI and high fat signal sequence. MRI found 7 cases of X-ray negative early iliac metastatic disease. Conclusion MRI is a better imaging method for evaluating iliac malignant bone tumors.
