“…However, this figure is significantly lower than that in other studies. Xu et al (22) reported noting rim-like enhancement in 79.6% (74/93) of RCCs. This difference may be due to the small size of the masses in the current study and the study by Jiang et al (20).…”

“…On CEUS and CECT minimal fat AMLs (both TAML and EAML types), show a centripetal enhancement in corticomedullary phase with homogeneous peak enhancement followed by iso-enhancement in parenchymal phase [24,25]. Oncocytomas are seen on CEUS exam as earlier spoke-like hyperenhancement, fast washout compared to the surrounding renal cortex, a nonenhanced rim, and central irregular nonenhanced areas [22].…”

“…The heterogeneous enhancement, a perilesional rim (pseudocapsula) and hypoenhancement in the late cortico-medullary and venous phase are the main characteristic traits of RCCs on CEUS or CECT exam (fig 6) [ [24][25][26].…”

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.

“…Time intensity curve in tumor formation had the same intensity as in the adjacent area) [4,5]. Probably slow uptake of contrast in the formation and continously wash out phase was due to the presence of granulomatous changes and caseous necrosis.…”

We describe a case of renal cell carcinoma which causes difficulties to set diagnosis with imaging methods. The histological examination revealed renal cell carcinoma associated with epithelioid cell granuloma with caseous necrosis. Granulomatous inflammation is characterized by the accumulation of epithelioid histiocytes and multinucleated giant cells. The cause of granuloma formation can be infectious or non-infectious. Granulomatous response in renal cell carcinoma is rare. This case shows that for accurate diagnosis for suspected tumor is necessary to be used combination of complex imaging -triplex ultrasound, CEUS, CT and histological examination.
