Calcified Peyronie's Disease Frequency on Computed Tomography

Area of Science:

• Radiology
• Urology
• Andrology

Background:

• Peyronie's disease, characterized by penile plaque formation, can calcify.
• Calcified Peyronie's disease may be incidentally discovered during abdominal computed tomography (CT).

Purpose of the Study:

• To determine the frequency of incidentally detected calcified Peyronie's disease in men undergoing abdominal CT.
• To characterize the location, laterality, and number of plaques in these cases.

Main Methods:

• Retrospective analysis of abdominal CT scans from 1968 male patients (January 2019 - January 2020).
• Two radiologists evaluated scans for calcified Peyronie's disease, recording plaque characteristics.
• Exclusion of scans with inadequate penile visualization.

Main Results:

• Calcified Peyronie's disease was identified in 130 (6.6%) patients.
• The condition was bilateral in 56.1% and unilateral in 43.9% of affected individuals.
• Multiple plaques were more common (66.1%) than single plaques (33.9%), with a predilection for the middle penile portion.

Conclusions:

• Incidental detection of calcified Peyronie's disease on abdominal CT is not uncommon.
• Findings suggest calcified Peyronie's disease often manifests as multiple, bilateral plaques, predominantly in the penile mid-shaft.
