Penile masses: Shear Wave Elastography correlated with Magnetic Resonance Imagining. A two cases report.

Abstract

Definitive diagnosis of penile masses usually depends on clinical symptoms and patient history but in some challenging cases the help of radiologic diagnostic tools is required. Although ultrasound is an effective tool for detecting penile masses, unlike magnetic resonance imagining, it is not able to differentiate benign and malignant pathologies. Shear wave elastography (SWE) is a novel method, which has the ability to differentiate malignant and benign tissues by giving quantitative information about tissue elasticity. In this paper we present two cases with penile masses to demonstrate the potential use of SWE in the differential diagnosis of penile masses.

Factors affecting the shear wave elastic quantitative measurement of penile tissue in rats

“…The SWQ value is correlated with the International Index of Erectile Function (IIEF-5) and Erection Hardness Scale (EHS) scores [ 11 ]. By measuring the penile SWQ value, 2D-SWE is able to detect and localize nonpalpable lesions in PD patients' curved penis undetected through conventional ultrasound [ 12 ], evaluate the degree of fibrosis in corpus cavernosum [ 13 ], differentiate the malignant from benign penile mass [ 14 ], and quantitatively evaluate the rigidity changes of corpus cavernosum in vascular ED patients [ 15 ]. Accurate assessment of the penile tissue composition seems imperative for the precise diagnosis of penile diseases.…”
