Rare primary bone sarcomas are challenging entities both radiologically and pathologically. These include the diagnoses of spindle cell sarcoma (leiomyosarcoma, fibrosarcoma, synovial sarcoma, and malignant peripheral nerve sheath tumor), pleomorphic liposarcoma, and undifferentiated pleomorphic sarcoma. The radiographic and cross-sectional imaging features of each of these tumors are presented, along with current key pathological concepts. Frequently non-specific, the radiological appearances must be correlated with all clinical and pathological information available to enable an accurate diagnosis.
罕见的原发性骨肉瘤在影像学和病理学上都是具有挑战性的实体。这些包括梭形细胞肉瘤（平滑肌肉瘤、纤维肉瘤、滑膜肉瘤和恶性外周神经鞘肿瘤）、多形性脂肪瘤和未分化多形性肉瘤的诊断。本文介绍了这些肿瘤的每一种的影像学和横断面成像特征，以及当前的关键病理学概念。这些影像学表现通常不具有特异性，必须与所有可用的临床和病理学信息相关联，以做出准确的诊断。
