The main imagistic method for characterization of renal lesions is contrast enhanced computed tomography (CECT). Disadvantages of CECT are a contrast-induced nephropathy in patients with renal impairment, allergic reactions and high costs. Contrast-enhanced ultrasound (CEUS) evaluation of hepatic and non-hepatic lesions is a relatively new, but increasingly utilised, diagnostic method. In 2011 the European Federation of Societies of Ultrasound in Medicine and Biology (EFSUMB) updated the Guidelines and Recommendations on the Clinical Practice of CEUS and included in the recommendation the renal pathology. However, there are several possible new indications that have not been discussed (pyelocaliceal masses and renal vein thrombosis) and several issues that remain controversial such as the differentiation of benign and malignant tumours or the differentiation of lymphoma and metastasis.This study aims to review literature data, as well as reveal the latest findings in the field of renal CEUS.

“…Gerst et al noted that while most ccRCCs showed peak intensity greater than cortex, the few ccRCCs in their study that did not were all lesions with greater than 16% necrosis or hyalinization [12]. Lu et al showed that ccRCC has a shorter TTP and RT than AML (RT was defined slightly differently on their study, as the time over which contrast increased from 10% to 90% of peak intensity) [38]. Overall enhancement of ccRCC is more commonly heterogeneous than the other subtypes and AML [37].…”

E568Cite as: Can Urol Assoc J 2015;9(7-8):E568-71. http://dx.doi.org/10.5489/cuaj.2749 Published online August 10, 2015. AbstractRenal angiomyolipomas (AML), consisting of fatty tissue, blood vessels, and smooth muscular cells in various proportions, is a relatively common benign renal neoplasm. Simultaneous involvement of the kidney and lymph nodes is uncommon and might be confused with an advanced renal cancer. AML is divided into minimal fat AML and fat-predominant AML. However, minimal fat AML with lymph node involvement is extremely rare and difficult to differentiate from RCC on images. We report such a case and review the literature.
