Abstract

Introduction: Clear cell sarcoma (CCS) of the soft tissue is a type of tumor that primarily affects the deep soft tissues of the extremities and trunk. We report a case of CCS of soft tissue arising in the first metacarpal of the hand, focusing on the imaging features of CCS combined with the clinicopathological and immunological results.

Case presentation: In this case, computed tomography images showed a soft tissue mass at the first metacarpal, with heterogeneous density, unclear boundaries, and bone destruction. On magnetic resonance imaging (MRI), the mass showed slightly higher signal intensity on T1-weighted images and mixed hyperintensity on T2-weighted images, with inhomogeneous enhancements. On both T1-weighted and T2-weighted sequences, there were some hypointense strips. No significant enhancements were found in these hypointense strips.

Conclusion: We suggest that hypointense strips on MRI should lead to the inclusion of CCS in differential diagnoses.

磁共振成像能提供具体诊断吗？手部第一掌骨软组织透明细胞肉瘤病例报告。

简介软组织透明细胞肉瘤（CCS）是一种主要侵犯四肢和躯干深部软组织的肿瘤。我们报告了一例发生于手部第一掌骨的软组织透明细胞肉瘤，重点介绍了透明细胞肉瘤的影像学特征以及临床病理学和免疫学结果：该病例的计算机断层扫描图像显示，第一掌骨处有一软组织肿块，密度不均，边界不清，骨质破坏。磁共振成像（MRI）显示，该肿块在 T1 加权图像上信号强度稍高，在 T2 加权图像上呈混合高密度，并伴有不均匀强化。在 T1 加权和 T2 加权序列上，都有一些低密度条带。结论：我们建议，磁共振成像上的低密度条带应导致将 CCS 纳入鉴别诊断。
