A prostatic utricle cyst, also known as a utricular cyst, is an area of focal dilatation that occurs within the prostatic utricle. They are midline cystic masses in the male pelvis and can be very difficult or impossible to distinguish from a Müllerian duct cyst.
Prostatic utricle cyst is a rare midline cystic lesion between the urinary bladder and the rectum, commonly associated with hypospadias. Along with its rarity, it presents a challenge in its diagnosis and proper management.
Utricle cysts are pear-shaped lesions usually smaller than 10 mm with a simple fluid signal on all modalities unless when complicated by infection or hemorrhage. Müllerian duct cysts are focal failure of regression and saccular dilatation of the embryological müllerian ducts.
A utricle cyst (or Müllerian duct cyst) presents with a midline cyst of the prostate and originates from the utricle. Histologically, a high PSA expression is typical. Squamous epithelium is not typical for a utricle cyst.
A prostatic utricle cyst, also known as a utricular cyst, is an area of focal dilatation that occurs within the prostatic utricle. They are midline cystic masses in the male pelvis and can be very difficult or impossible to distinguish from a Müllerian duct cyst .
Cysts of the lower male genitourinary tract are uncommon and usually benign. These cysts have different anatomic origins and may be associated with a variety of genitourinary abnormalities and symptoms.
Since almost 60% of adults diagnosed with a müllerian duct cyst did not experience any cyst related symptoms or ejaculatory-fertility impairment, we recommend that investigation and/or treatment should only be done in symptomatic or infertile patients.
Echographic criteria to define simple versus complicated cysts were detailed. We reviewed the clinical presentation, diagnostic modalities, indications for invasive procedures and postoperative outcome.
The cysts of the prostatic utricle are one of the possible causes of haematospermia in the young adult subject, a symptom that most of the time is painless, self-limiting and benign but its appearance may be frightening and alarming to the patient.
The prostatic utricle is a small, epithelium-lined diverticulum of the prostatic urethra. It is located in the verumontanum between the two openings of the ejaculatory ducts and extends backward and slightly upward for a very short distance within the medial lobe of the prostate.
