Renal leiomyoma is a challenging diagnostic and therapeutic condition. Given that 90% of leiomyomas originate from the renal capsule, leiomyoma presenting as a renal parenchymal mass is extraordinarily rare.
Herein, we report the clinical and imaging features of a patient with renal leiomyoma occurring in the renal parenchyma and mimicking renal cell carcinoma. We also review the clinical, imaging, and histological features of renal leiomyoma.
An initial partial, simple or radical nephrectomy according to tumor size and patient's underlying condition is suitable for larger, heterogeneous, and non-peripherally located tumors, even if they demonstrate hypointensity on T1- and T2-weighted images, considering the possibility of other diagnoses.
肾平滑肌瘤是一种具有挑战性的诊断和治疗病症。由于 90%的平滑肌瘤起源于肾包膜，因此作为肾实质肿块的平滑肌瘤极为罕见。
本文报告了一例发生在肾实质的肾平滑肌瘤的临床和影像学特征，其表现类似于肾细胞癌。我们还回顾了肾平滑肌瘤的临床、影像学和组织学特征。
根据肿瘤大小和患者的基础情况，初始行部分、单纯或根治性肾切除术适用于较大、异质性和非外周部位的肿瘤，即使它们在 T1 和 T2 加权图像上表现为低信号强度，也需要考虑其他诊断的可能性。
