Renal leiomyomas are not uncommon mesenchymal neoplasms of the kidney, found in 5% of autopsy specimens and comprising 0.3% of all treated tumors. These tumors arise from the smooth muscle cells of the kidney and are mostly located in the renal capsule. Typical imaging features of renal leiomyomas include a peripheral location, well-defined margins, and hyperattenuation on nonenhanced computed tomography (CT) images. The differential diagnosis of renal leiomyomas includes benign and malignant solid neoplasms of the kidney. Familiarity with typical renal leiomyoma imaging findings may help in the management of these patients and prevent unnecessary surgery.
肾平滑肌瘤是肾脏中较为常见的间叶性肿瘤，在5%的尸检标本中可发现，占所有治疗肿瘤的0.3%。这些肿瘤起源于肾脏的平滑肌细胞，大多位于肾包膜。肾平滑肌瘤的典型影像学特征包括位于周边、边界清晰，以及在非增强计算机断层扫描（CT）图像上呈高密度。肾平滑肌瘤的鉴别诊断包括肾脏的良性和恶性实性肿瘤。熟悉典型的肾平滑肌瘤影像学表现可能有助于这些患者的管理，并避免不必要的手术。
