ABSTRACT
We prospectively evaluated the performance of combined shear wave elastography (SWE) and conventional ultrasound (US) for the characterization of 89 testicular focal masses. Testes were evaluated with B-mode, color Doppler and SWE measurements, locating a region of interest on the normal and pathologic parenchyma. Thirty-seven malignant tumors (MTs), 12 burned out tumors (BOTs), 28 Leydig cell tumors (LCTs), 2 dermoid cysts and other benign lesions were included. MTsâ¯+â¯BOTs exhibited more microliths and macrocalcifications compared with benign lesions (p < 10-4). LCTs manifested mostly a dominant peripheral vascularization pattern compared with other lesions. MTsâ¯+â¯BOTs were stiffer compared with benign lesions (p < 2â¯×â¯10-4) but with a moderate area under the receiver operating characteristic curve (AUROC) of 80%. By focusing on LCTs versus MTsâ¯+â¯BOTs, diagnostic performance led to an AUROC of 89% for the best stiffness parameter. For combined conventional US and SWE, the diagnostic performance to differentiate all benign lesions versus MTsâ¯+â¯BOTs and LCTs versus MTsâ¯+â¯BOTs increased to AUROCs of 93% and 98%, respectively.
