    A Rare Case of Polyorchidism: Four Testes
    (Int Scientific Information Inc, 2016) Duymus, Mahmut; Menzilcioglu, Mehmet Sait; Cetincakmak, Mehmet; Avcu, Serhat
    Background: Polyorchidism or supernumerary testis means more than two testes. It is very rare and to the best of our knowledge, there have been only about 200 cases reported. Case Report: In this case report we want to present radiological features and assessment of a patient with four testicles. Conclusions: If the vascularity and echogenicity of the scrotal mass is similar with the normal testis parenchyma, multitestis should be considered. The MRI might not provide us with additional information to USG or CDUSG, thus it is not necessary to perform it if there is no suspicion of malignancy.

    Ultrasound elastography in kidney disease
    (Springer, 2016) Özkan, Fuat; Göya, Cemil; Yıldız, Sema; Duymuş, Mahmut; Menzilcioğlu, Mehmet Sait; Avcu, Serhat; İnci, Mehmet Fatih
    Ultrasound elastography is a relatively new imaging modality that can measure tissue elasticity quantitatively by using different techniques. With the development of technology, kidney elasticity measurements can be performed accurately and quickly using ultrasound. Nowadays, kidney stiffness is used not only in fibrosis but also in the characterization of focal lesions, staging of metabolic kidney damage including diabetes mellitus, gout disease, etc.., and evaluating renal damage in urinary tract abnormality. However, kidney is a unique tissue and has a complex internal architecture. Therefore intrinsic or extrinsic factors such as perfusion, urinary pressure, anisotropy, depth of kidney, and hydronephrosis may affect the viscoelasticity of the kidney. Elastography is a useful, quick, noninvasive complementary method in the diagnosis of kidney diseases but needs specific training and optimization techniques as well as acknowledging technical and pathological factors whichmay influence it.
