ABSTRACT
OBJECTIVES:
The purpose of this study was to evaluate the ability of shear wave elastography (SWE) to differentiate seminomas from nonseminomatous germ cell tumors.METHODS:
Approval for this retrospective study was obtained from the local Ethics Committee of Istanbul University Cerrahpasa Medical School. Fifteen patients with malignant testicular lesions were examined by grayscale sonography, color or power Doppler sonography, and SWE between February 2011 and October 2015. The size of each lesion, Doppler signal parameters, echogenicity, presence of microlithiasis, unifocality or multifocality, and histopathologic findings were the main factors evaluated.RESULTS:
The mean age of the patients was 33 years (range, 25-55 years). There were no differences between seminomas and nonseminomatous germ cell tumors in terms of Doppler signals, echogenicity, microlithiasis, or focality. Only the homogeneous and heterogeneous echogenicity patterns differed significantly. However, a significant difference was evident in SWE-derived quantitative data.CONCLUSIONS:
Seminomas and nonseminomatous germ cell tumors do not differ significantly on grayscale or Doppler sonography, except in terms of homogeneity. However, SWE seems to differentiate seminomas from nonseminomatous germ cell tumors.Palavras-chave
