1. MRI显示先前的囊性病变增大了一倍多，现在出现了实性强化。这些影像学发现现在是一个快速增长的恶性肿瘤，经进一步检查证实是恶性横纹肌样瘤（MRT）。肾肿瘤占所有儿童恶性肿瘤的7%。mrt是一种罕见的侵袭性肿瘤，占所有肾恶性肿瘤的不到2%。它通常在0至3岁的儿童中被诊断出来。这种肿瘤通常表现为位于中央的巨大小叶软组织肿块，伴有出血、坏死和边缘钙化[1,3]。我们的患者最初的MRI显示钙化与出血性病变，只是，重复成像显示更多的经典发现，因此鼓励我们考虑肿瘤过程。
1. The MRI showed that the previous cystic lesion had more than doubled in size and now appeared to have areas of solid enhancement. These imaging findings were now concerning for a rapidly growing malignancy, which upon further work-up proved to be a malignant rhabdoid tumor (MRT).Kidney tumors account for 7% of all childhood malignancies. MRTs are a rare, aggressive type of tumor that account for less than 2% of all kidney malignancies [1]. It is generally diagnosed in children between 0 and 3 years of age [2]. This tumor generally presents as a large, centrally located lobular soft-tissue mass with hemorrhage, necrosis, and a calcified rim [1, 3]. Our patient’s initial MRI revealed a calcified vs. hemorrhagic lesion, only, with repeat imaging revealing more of the classic findings, thereby encouraging us to consider an oncologic process.
