“…Benign renal neoplasms are classified into renal cell, metanephric, mesenchymal, mixed epithelial and mesenchymal, neuroendocrine, and germ cell tumors [4,5]. Benign mesenchymal tumors consist of angiomyolipomas, leiomyomas, hemangiomas, lymphangiomas, juxtaglomerular cell tumors, renomedullary interstitial cell tumors (medullary fibromas), lipomas, solitary fibrous tumors, and schwannomas.…”

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, welldefined 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.

“…HCA are often hypervascular and may appear heterogeneous due to the presence of fat, necrosis, or hemorrhage [39,40]. T1-weighted chemical shift or DIXON imaging is useful for detecting intratumoral fat, while the presence of high T1-signal before contrast administration will raise the suspicion of spontaneous hemorrhage.…”

“…On ultrasound, they appear as small hyperechoic or hypoechoic lesions and can demonstrate ringing artifacts (comet tail appearance). On CT, they appear as small cystic lesions of round, oval, or irregular shape without contrast enhancement, although thin rim enhancement may sometimes be present, thus mimicking hypovascular liver metastases [40].…”
