软骨肉瘤(CS)是一种影响骨骼的恶性肿瘤,而非典型软骨肿瘤(ACTs)是具有中等细胞性的软骨肿瘤,轻度非典型性,伴有粘液样改变和轻度转移能力。如果没有足够早的识别,两者都可能具有最差的预后之一。磁共振成像(MRI)一直是检测此类肿瘤的方式之一,我们的目标是确定筛查CS或ACT时要看到的共同特征和特征。我们对以前发表的报告进行了系统的回顾,这些报告研究了MRI的诊断能力以及可以区分ACTs和高级软骨肉瘤(HGCS)的报道特征。进行了全面的相关数据库搜索,以包括所有相关研究。在这些研究中,七项研究调查了不同软骨瘤类型分类的总体准确性。此外,许多研究根据MRI结果报道了每个肿瘤的特征性发现。这些特征主要包括被困脂肪,骨髓水肿,皮质损伤,和软组织扩张。因此,应进一步注意这些标准,以便更好地评估,分化,和有利的结果。MRI可以有效地识别ACTs和HGCS的一些特征。然而,将其与其他放射学模式相结合可能会导致更好的区分。以前在文献中一直怀疑仅使用MRI检测ACTs和HGCS病变。
Chondrosarcoma (CS) is a malignant tumor affecting the bones while atypical cartilaginous tumors (ACTs) are chondral tumors with moderate cellularity, mild atypia, and with myxoid changes and mild metastatic ability. Both can have one of the worst prognoses if not identified early enough. Magnetic resonance imaging (MRI) has been one of the modalities to detect such tumors and we aim to determine the common characteristic and features to be seen while screening for CS or ACTs. We conducted a systematic review of the previously published reports that investigated the diagnostic ability of MRI and the reported characteristics that can differentiate between ACTs and high-grade chondrosarcomas (HGCS). A comprehensive relevant database search was performed to include all the relevant studies. Among these studies, seven studies investigated the overall accuracy in the classification of the different chondroma types. Additionally, many studies reported the characteristic findings of each tumor according to the MRI results. These characteristics mainly included trapped fat, bone marrow edema, cortical damage, and soft-tissue expansion. Therefore, further attention should be given to these criteria for better assessment, differentiation, and favorable outcomes. MRI can efficiently identify some of the characteristics of both ACTs and HGCS. However, combining it with other radiological modalities may lead to a better differentiation. The detection of ACTs and HGCS lesions with MRI solely has been doubted before in the literature.
