<aside>

Peyronie’s disease is a fibroproliferative disorder of the tunica albuginea of the penis, leading to fibrous plaque formation, progressive penile curvature, pain, and sometimes erectile dysfunction. It is a localized connective tissue disorder, most common in middle-aged to older men.

Pathophysiology


Feature Description
Affected structure Tunica albuginea (fibrous sheath surrounding corpora cavernosa)
Mechanism Repetitive microtrauma during intercourse → abnormal wound healing → fibrosis and calcification
Disease course Initial active/inflammatory phase → chronic fibrotic/stable phase

Epidemiology


Feature Description
Prevalence ~3–9% of adult men
Age Peak incidence: 50–60 years
Risk factors Diabetes, Dupuytren’s contracture, trauma, connective tissue disorders, penile fracture history

Clinical Features


Phase Symptoms
Acute/inflammatory Penile pain (especially during erection), palpable plaque, mild curvature
Chronic/fibrotic Stable penile deformity, curvature (>30°), penile shortening, erectile dysfunction
Palpable lesion Firm, non-tender plaque along dorsal or dorsolateral shaft
Sexual dysfunction Due to curvature, deformity, pain, or associated vascular disease

Radiology


Modality Imaging features
US US is best for real-time, high-resolution detection of superficial plaques, especially in the dorsal shaft.
• Hyperechoic, calcified plaques in tunica albuginea, usually dorsal
• Non-calcified plaques: hypoechoic or heterogeneous
• Doppler: Assess penile vascularity and arterial inflow; may show decreased flow if vascular compromise
• Elastography: May quantify stiffness of fibrotic plaques (optional in chronic phase)
MR Indications: Atypical cases, deep plaques, surgical planning, or suspected intracavernosal involvement
• T1: Plaques appear as low-to-intermediate signal
• T2: Low signal intensity (fibrosis/calcification) in tunica albuginea
• Post-contrast: May show enhancement in early/inflammatory stage
XR Dystrophic calcifications along dorsal shaft

Differentials


Condition Distinguishing Features
Penile fracture History of trauma, tunica disruption, hematoma
Calcified corpus cavernosa Deep, not limited to tunica; diffuse cavernosal involvement
Penile cancer Irregular mass, T2 hyperintensity, heterogeneous enhancement
Vascular erectile dysfunction No palpable plaque; abnormal cavernosal artery Doppler parameters

Management


Phase Treatment Options
Acute (active) NSAIDs, pentoxifylline, oral vitamin E, collagenase Clostridium histolyticum (CCH) injections
Chronic (stable) Surgery for severe deformity or functional disability:
Plaque excision + grafting
Plication procedures
Penile prosthesis (if erectile dysfunction present)
Traction therapy: Penile extenders to reduce curvature and shortening
