软骨样脂肪瘤是一种罕见的脂肪瘤变体，病理学上类似脂肪肉瘤或其他肉瘤。脂肪瘤的变体，包括软骨样脂肪瘤，可能会显示肿瘤内脂肪的放射学证据，但在影像学研究中往往显示异质性特征，使临床诊断困难。由于软骨样脂肪瘤的罕见性，缺乏大量关于其影像学特征的集体经验。我们报告一位37岁的女性，发生于大腿上部的软骨样脂肪瘤，肿瘤内有化生性骨形成。影像学上，肿瘤表现为一个巨大的软组织肿块，伴有钙化和骨化。虽然在传统的脂肪瘤中化生骨的形成是很好的描述，但很少报告发生在软骨样脂肪瘤中，并且没有病理学记录或说明。影像学表现和组织病理学这一不寻常的肿瘤，沿着的文献回顾。
Chondroid lipoma is a rare variant of lipoma that pathologically can mimic liposarcoma or possibly other sarcomas. Variants of lipoma, including chondroid lipoma, may demonstrate radiological evidence of fat within the tumor, but often display heterogeneous features on imaging studies, making a clinical diagnosis difficult. A large collective experience with the imaging characteristics of chondroid lipoma is lacking due to the rarity of this tumor. We present a case of chondroid lipoma of the upper thigh in a 37-year-old woman who had regions of metaplastic bone formation within the tumor. Radiologically, the tumor presented as a large soft tissue mass with calcification and ossification. Although metaplastic bone formation in conventional lipoma is well described, it has been rarely reported to occur in chondroid lipoma and has not been pathologically documented or illustrated. The imaging findings and histopathology of this unusual tumor are presented, along with a review of the literature.
