目的 分析软骨肉瘤的影像学特点,为其临床诊断提供参考.方法 选取2010年2月至2014年1月于右江民族医学院附属医院就诊的30例软骨肉瘤患者,其中14例接受数字化X线摄影、CT及磁共振成像(MRI)检查,12例接受X线及CT检查,4例接受CT及MRI检查;9例接受增强CT检查,3例接受增强MRI检查.回顾性分析患者影像学资料并分析其特点.结果 30例患者中15例软骨肉瘤起源于骨盆三角.临床病理分型26例为原发型,4例为继发型.原发型患者中普通型23例,黏液型、透明细胞型及去分化型各1例.3例普通型及1例透明细胞型X线表现为扇贝样压迫性骨破坏.CT表现多为密度低或稍低的肿块影,23例普通型及1例黏液型患者病灶区域可见散在的点状、弧状、环状及绒毛状钙化灶.MRI表现:普通型软骨肉瘤T1WI呈等信号或略低信号,T2WI呈等信号或略高信号;黏液型软骨肉瘤T1WI呈等信号或低混杂信号,T2WI呈略高或略低的混杂信号;钙化灶T2 WI呈低信号;去分化型T1WI主要呈低信号,且可见散在斑片状稍高信号,而T2WI表现为双相征的不均匀高信号;透明细胞型软骨肉瘤T1WI及T2WI呈均匀的等信号,边缘可见扇贝样压迹.9例患者接受增强CT扫描,3例患者接受增强MRI检查,其中普通型及继发型患者可出现环形、间隔样中等强化灶,去分化型及黏液型呈不均匀中等强化灶,内部可见散在小房间隔样强化.结论 CT及X线可以作为软骨肉瘤患者的首选检查方式,MRI显示病变范围更加清晰、准确,可以为临床诊断此类患者提供参考.
目的 分析軟骨肉瘤的影像學特點,為其臨床診斷提供參攷.方法 選取2010年2月至2014年1月于右江民族醫學院附屬醫院就診的30例軟骨肉瘤患者,其中14例接受數字化X線攝影、CT及磁共振成像(MRI)檢查,12例接受X線及CT檢查,4例接受CT及MRI檢查;9例接受增彊CT檢查,3例接受增彊MRI檢查.迴顧性分析患者影像學資料併分析其特點.結果 30例患者中15例軟骨肉瘤起源于骨盆三角.臨床病理分型26例為原髮型,4例為繼髮型.原髮型患者中普通型23例,黏液型、透明細胞型及去分化型各1例.3例普通型及1例透明細胞型X線錶現為扇貝樣壓迫性骨破壞.CT錶現多為密度低或稍低的腫塊影,23例普通型及1例黏液型患者病竈區域可見散在的點狀、弧狀、環狀及絨毛狀鈣化竈.MRI錶現:普通型軟骨肉瘤T1WI呈等信號或略低信號,T2WI呈等信號或略高信號;黏液型軟骨肉瘤T1WI呈等信號或低混雜信號,T2WI呈略高或略低的混雜信號;鈣化竈T2 WI呈低信號;去分化型T1WI主要呈低信號,且可見散在斑片狀稍高信號,而T2WI錶現為雙相徵的不均勻高信號;透明細胞型軟骨肉瘤T1WI及T2WI呈均勻的等信號,邊緣可見扇貝樣壓跡.9例患者接受增彊CT掃描,3例患者接受增彊MRI檢查,其中普通型及繼髮型患者可齣現環形、間隔樣中等彊化竈,去分化型及黏液型呈不均勻中等彊化竈,內部可見散在小房間隔樣彊化.結論 CT及X線可以作為軟骨肉瘤患者的首選檢查方式,MRI顯示病變範圍更加清晰、準確,可以為臨床診斷此類患者提供參攷.

Objective To analyze the imaging features of chondrosarcoma.Methods Inaging data of 30 patients with chondrosarcoma from February 2010 to January 2014 were retrospectively analyzed.Forteen patients underwent digital X-ray camera system (DR), CT and magnetic resonance imaging (MRI), 12 underwent DR and CT examination, 4 patients underwent CT and MRI;enhanced CT was performed in 9 cases and enhanced MRI was performed in 3 cases.The imaging features were analyzed.Results Most of the chondrosarcomas originated from pelvis triangle.According to the clinical pathological type, 26 cases were primary type (including 3 of conventional type, 1 of mucinous type, 1 of clear cell type and 1 of de-differentiation type) and 4 cases were secondary type.In X-ray image, scallop like compression destruction of the bone was shown in 3 cases of common type and 1 case of clear cell type.In CT, the lesions manifested as low or slightly low density masses;the spotty, arcus, cyclic and villous calcifications were scattered in the lesions in 23 cases of common types and 1 tpye of mucinous type.In MRI, the chondrosarcomas of common type manifested as isointense or slight low signal in T1 weighted imaging (T1 WI) and isointense or slight high signal in T2WI;the chondrosarcomas of mucinous type manifested as isointense or low hybrid signal in T1 WI and slight low or high hybrid signal in T2WI;the calcifications in T2WI showed as low signal;the chondrosarcomas of de-differentiation type mainly manifested as low signal with sporadic patchy slight high signal in T1WI and a biphasic sign of uneven high signal in T2WI;the chondrosarcomas of clear cell type showed homogeneous isointensity signal on T1 WI and T2 WI, with scallop like impression on the edge.In 9 cases undergoing enhanced CT and 3 cases undergoing enhanced MRI, annular and septal moderate enhancement were observed in common type and secondary type;inhomogeneous moderate enhancement with small room enhancement scattering was observed in de-differentiation type and mucous type.Conclusions CT and X-ray are the preferred method to diagnose chondrosarcoma;MRI shows the lesions range more clearly and accurately, and can provide important reference for clinical treatment.
