Abstract:
We report MR imaging characteristics of a prostatic urethral polyp in a 35-year-old man. Traditionally, the methods of diagnosis include computed tomography, transrectal sonography, voiding cysto-urethrography, intravenous pyelography, urethroscopy, and cystoscopy. To our knowledge, MR findings have not been previously described. In this case, MR imaging clearly demonstrated a polypoid tumor located in the prostatic urethra with a stalk connected to the bladder neck. A pathological study revealed the polyp consisted of a fibrovascular core covered with a double layered, prostatic-type epithelium.
Insights
Magnetic Resonance (MR) imaging revealed a prostatic urethral polyp in a 35-year-old man, detailing its unique characteristics. This case highlights MR imaging as a valuable tool for diagnosing prostatic urethral polyps.
Area of Science:
- Urology
- Radiology
- Pathology
Background:
- Prostatic urethral polyps are rare benign tumors.
- Traditional diagnostic methods include CT, ultrasound, and cystoscopy.
- MR imaging findings for this condition have not been previously documented.
Observation:
- A 35-year-old male patient presented with symptoms suggestive of a urethral obstruction.
- MR imaging was performed to evaluate the prostatic urethra.
- The imaging revealed a distinct polypoid lesion.
Findings:
- MR imaging clearly depicted a polypoid tumor within the prostatic urethra.
- The polyp was observed to have a stalk connecting to the bladder neck.
- Pathological examination confirmed a fibrovascular core with prostatic-type epithelium.
Implications:
- This study establishes the MR imaging characteristics of a prostatic urethral polyp.
- MR imaging offers a non-invasive method for diagnosing prostatic urethral polyps.
- Accurate diagnosis can guide appropriate clinical management and treatment strategies.

Urethra
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...
