Leiomyosarcoma of the Renal Vein: Imaging and Surgical Reconstruction

Renal vein leiomyosarcoma and renal cell carcinoma presenting together: A case report and discussion on the follow up.

“…5 Kaushik described the typical CT appearance as a homogenous, well-circumcised solid mass with minimal contrast enhancement in the region of the renal hilum, 7 as seen in our case. Recently Maturen and colleagues reviewed the radiological imaging for 5 cases of renal vein leiomyosarcoma.…”

Leiomyosarcoma of the renal vein: Arterial encasement on contrast‐enhanced dynamic computed tomography

“…1 Primary leiomyosarcomas originating from renal veins are extremely rare and approximately 30 cases have been reported in the published English language literature. 2,3 We report a case of leiomyosarcoma of the renal vein encasing the renal artery, inconsistent with previously reported manifestation.…”

Multidetector CT and MR Imaging Findings of Renal Vein Leiomyosarcoma with Both Extraluminal and Intraluminal Components: A Case Report

“…Primary leiomyosarcoma originating from the renal vein is quite uncommon with 50 to 60 years as prevalence peak age. It more commonly arises from the right renal vein compared to the left renal vein (2,4). Long-term outcomes are closely related to tumor size and the feasibility of complete tumor resection (5).…”

“…The renal vein leiomyosarcoma is grossly classified into three subtypes: completely extravascular; completely intravascular and mixed (1,4). To the best of our knowledge, there have been only few reports detailing the imaging findings of renal leiomyosarcoma with both extra-and intravascular components (1,4). We report an uncommon case of left renal vein leiomyosarcoma with combined components, focusing on the multidetector computed tomography (MDCT) and MR imaging findings with review of the literature.…”

“…After the first report of Varela and Garro in 1967, only about 30 cases have been reported in the published medical literature (2,3). The renal vein leiomyosarcoma is grossly classified into three subtypes: completely extravascular; completely intravascular and mixed (1,4). To the best of our knowledge, there have been only few reports detailing the imaging findings of renal leiomyosarcoma with both extra-and intravascular components (1,4).…”
