Congenital-infantile, fibrosarcoma is a rare tumour presenting at birth or in the neonatal period. Few such tumours have been reported, and imaging details in particular are scant. The authors describe two neonates with congenital-infantile fibrosarcoma, the first case involving the right thigh and extending into the pelvis, and the second involving the calf and the ankle. In both cases magnetic resonance imaging (MRI) demonstrated well-demarcated, low-signal-intensity soft-tissue masses with t1-weighting and inhomogeneous, high-signal-intensity masses with T2-weighting. MRI was superior to other imaging modalities in the assessment of soft-tissue involvement and proved especially useful in planning therapy and monitoring chemotherapeutic response.
先天性婴儿纤维肉瘤是一种罕见的肿瘤，在出生时或新生儿期出现。此类肿瘤报道较少，尤其是影像学细节稀缺。作者描述了两例先天性婴儿纤维肉瘤的新生儿病例，第一例累及右大腿并延伸至骨盆，第二例累及小腿和脚踝。在这两例病例中，磁共振成像（MRI）在T1加权像上显示为边界清晰的低信号强度软组织肿块，在T2加权像上显示为不均匀的高信号强度肿块。在评估软组织受累方面，MRI优于其他成像方式，并且在规划治疗和监测化疗反应方面证明特别有用。
