Summary

Magnetic resonance imaging (MRI) effectively evaluates the seminal tract in patients experiencing hemospermia, revealing abnormalities missed by transrectal ultrasound. This advanced imaging technique aids in diagnosing the causes of blood in semen.

Area of Science:

  • Urologic imaging and diagnostics
  • Male reproductive system anatomy and pathology

Background:

  • Hemospermia, or blood in semen, is a concerning symptom requiring thorough investigation.
  • Conventional imaging like transrectal ultrasound (TRUS) has limitations in fully assessing the seminal tract.

Purpose of the Study:

  • To evaluate the diagnostic utility of magnetic resonance imaging (MRI) for the prostate and seminal tract in patients with hemospermia.
  • To compare MRI findings with transrectal ultrasound (TRUS) in this patient cohort.

Main Methods:

  • Seventeen patients with hemospermia underwent both transrectal ultrasound (TRUS) and MRI.
  • MRI was performed using an endorectal surface coil on a 1.5 tesla unit.
  • Patient age ranged from 20 to 59 years, with a mean duration of hemospermia of 32 months.

Main Results:

  • MRI detected abnormalities in all 17 patients (100%), significantly higher than TRUS (88%).
  • Hemorrhage originated from the seminal vesicle in 10 cases and the ejaculatory duct in 2.
  • Common findings included cystic lesions (müllerian and ejaculatory ducts) and calculi (prostate, seminal vesicle, ejaculatory ducts).

Conclusions:

  • MRI with an endorectal surface coil is a powerful tool for evaluating seminal tract pathology in hemospermia.
  • MRI offers superior diagnostic capability compared to TRUS, especially when TRUS findings are inconclusive.
  • This modality can be clinically valuable for identifying the source and nature of hemospermia.
