【摘要】：目的回顾性分析下肢骨巨细胞瘤CT和MRI表现与术后复发的相关性,为预测术后复发及制定临床诊疗方案提供影像学依据。方法回顾1999年至2014年59例下肢骨单发骨巨细胞瘤患者术后复发情况,分析其术前CT与MRI影像资料。观察CT骨棘与骨皮质破坏表现及MRI囊性变、周围组织水肿、瘤内液化坏死出血、软组织侵袭及肿瘤边缘低信号是否完整等表现,并分析以上表现与复发的相关性。结果 MRI所示的瘤内出血液化坏死表现在复发与无复发两组中具有统计学差异(P0.05)。其余影像学表现在复发与无复发两组中均无统计学差异。结论骨巨细胞瘤MRI所示的瘤内出血液化坏死表现与肿瘤术后复发相关,对临床治疗方案的制定具有指导意义。
[Abstract]:Objective to retrospectively analyze the correlation between CT and MRI findings of giant cell tumor of lower limb and postoperative recurrence. Methods from 1999 to 2014, 59 patients with single giant cell tumor of lower extremity bone were retrospectively reviewed. The CT and MRI imaging data were analyzed before operation. The destruction of bone spine and bone cortex, MRI cystic degeneration, edema of surrounding tissue, liquefaction necrosis and hemorrhage in tumor, soft tissue invasion and the integrity of tumor edge were observed. The correlation between the above findings and recurrence was analyzed. Results there was a significant difference between recurrent and non-recurrence groups in the manifestation of liquefaction necrosis of tumor bleeding in MRI. The other imaging findings were not uniform in both groups. Conclusion the manifestation of hemorrhage and liquefaction necrosis in giant cell tumor of bone (MRI) is related to the recurrence of tumor after operation. It is of guiding significance to the formulation of clinical treatment plan.
