This ultrasound depicts cross sections of the penis at different locations in a patient with<unk> . The top image shows normal anatomy whereas the bottom image shows scar tissue on the tunica albuginea (penis). The scar tissue is localized and responsible for the hallmark deformities of<unk>  (curvature and narrowing). A urologist may be able to diagnose the disease and suggest treatment. An ultrasound can provide conclusive evidence of<unk> , ruling out congenital curvature or other disorders. Ultrasonography On penile ultrasonography, the typical appearance is hyperechoic focal thickening of the tunica albuginea. Due to associated calcifications, the imaging of patients with<unk>  shows acoustic shadowing, as illustrated in figures below. Less common findings, attributed to earlier stages of the disease (still mild fibrosis), are hypoechoic lesions with focal thickening of the paracavernous tissues, echoic focal thickening of the tunica without posterior acoustic shadowing, retractile isoechoic lesions with posterior attenuation of the beam, and focal loss of the continuity of the tunica albuginea. In the Doppler study, increased flow around the plaques can suggest inflammatory activity and the absence of flow can suggest disease stability. Ultrasound is useful for the identification of lesions and to determine their relationship with the neurovascular bundle. Individuals with<unk>  can present with erectile dysfunction, often related to venous leakage, due to insufficient drainage at the site of the plaque. Although plaques are more common on the dorsum of the penis, they can also be seen on the ventral face, lateral face, or septum.CC-BY license File:Ultrasonography of orpus cavernosum calcification.Transverse ultrasound of the penis, in a ventral view, in the middle portion of the penis.
