A rare case of a spontaneous abscess of the corpus cavernosum: the role of contrast-enhanced ultrasound in diagnosis and post-therapeutic follow-up.

In this paper, we describe the pattern of an idiopathic corpus cavernosum (CC) abscess using contrast-enhanced ultrasound (CEUS) and compare this to the lesion characterization achieved using preliminary baseline ultrasound/color doppler (ECD). In a 43-year-old man, who arrived at our emergency department for a penile swelling and hematopyuria, ECD examination showed equivocal mucosal and subcutaneous tissue swelling, an inhomogeneous hypoechoic area in the left CC, and a suspected millimetric interruption of the albuginea. CEUS showed multiple avascular areas wrapped in a hyperperfused rim representing abscesses and a not-perfused balanopreputial-oriented fistula. A CEUS control documented clinical remission after surgery. CEUS is a noninvasive and bedside executable method that allows a more precise evaluation of the entity, localization, and possible complications of CC abscesses and, therefore, permits prescribing the most adequate therapy to the patient, as well as the evaluation of eventual postsurgical sequelae.
