目的探讨骨恶性纤维组织细胞瘤的X线及MRI表现,提高对该病的诊断水平。方法回顾性分析经手术及病理证实的骨恶性纤维组织细胞瘤患者9例,所有患者均摄病变部位X线正侧位片,其中6例患者行MRI检查。结果本组患者发病部位均为长骨,X线表现为病变区溶骨性破坏,形态不规则,呈地图状、虫咬状或斑片状,与周围正常骨质分界不清,中心无残留骨小梁。骨皮质膨胀变薄,形态不规则。MRI检查T1WI上肿瘤组织呈低等信号,T2WI上呈不均匀高低混杂信号,肿胀软组织表现为长T1、长T2信号,边缘不清。结论骨恶性纤维组织细胞瘤发病部位以长骨多见,X线及MRI表现溶骨性骨质破坏伴软组织肿块,但缺乏特征性,临床确诊依靠组织病理学检查。
Objective To investigate the X-ray and MRI findings of malignant fibrous histiocytoma and to improve the diagnosis of the disease. Methods Nine patients with malignant fibrous histiocytoma confirmed by surgery and pathology were retrospectively analyzed. All the patients underwent X - ray radiography of the lesion and 6 of them were examined by MRI. Results The incidence of this group of patients are long bones, X ray showed lesions of osteolytic destruction, irregular shape, map-like, insect bite or patchy, with the surrounding normal bone demarcation is not clear, the center without residual bone Trabecular. Cortical expansion thinning, irregular shape. Tumor MRI showed low signal intensity on T1WI, uneven high and low mixed signal on T2WI, swollen soft tissue showed long T1 and long T2 signal, and the margin was unclear. Conclusion The incidence of malignant fibrous histiocytoma is mostly seen in long bones. X-ray and MRI show osteolytic bone destruction accompanied by soft tissue mass. However, it is characterized by a lack of characteristic features. The clinical diagnosis depends on histopathological examination.
