“…At MR imaging, leiomyoma typically has homogeneously low signal intensity on T1-and T2-weighted images. However, larger tumors show mixed signal intensity on MR images that is caused by myxoid or cystic degeneration, hemorrhage, and calcifications (14,15). Larger tumors are indistinguishable from renal cell carcinoma and leiomyosarcoma with imaging studies.…”

Mesenchymal neoplasms of the kidney in adults cover a wide spectrum with characteristic ontogeny and histologic findings and variable biologic profiles and imaging findings. Benign mesenchymal renal tumors include angiomyolipoma, leiomyoma, hemangioma, lymphangioma, juxtaglomerular cell tumor, renomedullary interstitial cell tumor (medullary fibroma), lipoma, solitary fibrous tumor, and schwannoma. Malignant renal tumors of mesenchymal origin include leiomyosarcoma, rhabdomyosarcoma, angiosarcoma, osteosarcoma, synovial sarcoma, fibrosarcoma, malignant fibrous histiocytoma, and solitary fibrous tumor. Cross-sectional imaging findings for mesenchymal renal tumors in adults are varied. Although angiomyolipomas and lipomas show macroscopic fat, lymphangiomas are cystic in appearance. Renal hemangioma may show phleboliths and a characteristic enhancement pattern. Leiomyoma typically arises from the capsule and causes buckling of the renal cortex. Although osteosarcoma may demonstrate characteristic dense ossification, most renal sarcomas demonstrate imaging features that are indistinguishable from the more common renal cell carcinoma. Although some renal mesenchymal tumors have typical imaging findings, biopsy is warranted to establish a definitive diagnosis. Awareness of the various mesenchymal renal tumors and familiarity with their imaging findings permit optimal patient management.

“…On MRI, they appear homogeneously hypointense due to compact tumor cells on T1 and T2 weighted imaging sequences. 20 Plasmacytoma is a plasma cell neoplasm that may manifest as primary amyloidosis, multiple myeloma, or monoclonal gammopathy of unknown significance. They can have osseous (medullary) or nonosseous (extramedullary) origins.…”

The expanded application of radiologic imaging resulted in an increased incidence of renal masses in the recent decade. Clinically, it is difficult to determine the malignant potential of the renal masses, thus resulting in complex management. Image-guided biopsies are the ongoing standard of care to identify molecular variance but are limited by tumor accessibility and heterogeneity. With the evolving importance of individualized cancer therapies, radiomics has displayed promising results in the identification of tumoral mutation status on routine imaging. This article discusses how magnetic resonance imaging features can guide a radiologist toward identifying renal mass characteristics.

Magnetic resonance imaging with computed tomography of a renal leiomyoma

Abstract: Renal leiomyoma are rare, benign tumors of the kidney. There is little information about the imaging of these tumors with modern modalities. We present a case of computed tomographic (CT) and magnetic resonance (MR) imaging of a large renal leiomyoma.
