▶ The linear calcifications along the tunica albuginea noted here are suggestive of calcified plaques seen in Peyronie’s disease. Penile tumors present as irregular soft tissue masses on ultrasound. A penile foreign body can appear as a linear shadowing structure on ultrasound, but suggestive history is usually available.
▶ Peyronie’s disease is characterized by formation of fibrous tissue plaques within the tunica albuginea. Plaque formation causes penile deformity.
▶ Etiology is unclear but may be due to microtrauma and subsequent aberrant scar formation.
▶ Penile deformity, palpable plaques, and pain are presenting complaints.
▶ Peyronie’s disease has an acute inflammatory stage followed by stabilization of symptoms.
▶ Ultrasound is used to identify the extent and location of palpable and nonpalpable plaques.
▶ Plaques are identified as areas of focal hyperechoic thickening of the tunica albuginea with associated shadowing. Plaque calcifications are associated with disease stabilization.
▶ On MRI, plaques appear as T1 and T2 hypointense areas in the tunica.
