Summary: | To describe the contrast-enhanced ultrasonographic appearance of various focal, space-occupying renal lesions and determine its value in their detection and characterization. Following baseline B-mode sonography of 15 dogs and one cat with renal space-occupying lesion(s), contrast-enhanced sonography was performed. The resulting images were evaluated qualitatively using conspicuity and number of lesions, and enhancement patterns were assessed during early arterial and late corticomedullary phases. Renal lesions were malignant in the cat (renal cell carcinoma) and 10 dogs (four renal cell carcinoma, two histiocytic sarcoma, one B-cell lymphoma, two hemangiosarcoma metastasis, one chemodectoma metastasis) and benign in five dogs (two abscesses, one traumatic hematoma, one idiopathic hematoma, one hemorrhagic/necrotic nodule). Substantial overlap was present regarding the baseline sonographic features of benign vs. malignant lesions. With contrast-enhanced sonography, all renal cell carcinomas were characterized by large tortuous arteries, sometimes enhancing slightly earlier than vessels in the surrounding normal kidney. During the late corticomedullary phase, renal cell carcinomas had intense homo- or heterogeneous, iso- or slightly hypoechoic enhancement, which decreased progressively. Compared with renal cell carcinoma, histiocytic sarcoma and lymphoma had smaller and less obvious arteries, and an earlier loss of enhancement during the late phase. All hemangiosarcoma metastases appeared as nonenhancing nodules during the early arterial and late corticomedullary phases of enhancement, and additional lesions were detected. Histiocytic sarcoma and benign lesions had increased conspicuity with baseline sonography. The descriptions provided herein will be valuable as more work is done to establish the role of contrast-enhanced sonography in the assessment of renal lesions. |
