Summary
This case study highlights polyorchidism, a rare condition where an individual has more than two testes. High-resolution sonography accurately diagnosed an accessory testis, proving effective for polyorchidism diagnosis.
Area of Science:
- Urology
- Radiology
- Medical Imaging
Background:
- Polyorchidism is a rare congenital anomaly characterized by the presence of supernumerary testes.
- Diagnosis often relies on imaging modalities, but non-invasive methods are preferred.
Observation:
- A case of polyorchidism was diagnosed in a patient presenting with a palpable mass inferior to the left testis.
- Sonographic examination revealed an accessory testis with its own epididymis, measuring 1.0 x 0.8 x 0.6 cm.
- The accessory testis exhibited similar echotexture and normal blood supply via color Doppler sonography.
Findings:
- High-resolution sonography accurately identified and characterized the accessory testis.
- Magnetic Resonance Imaging (MRI) confirmed the sonographic findings.
- The accessory testis possessed a distinct epididymis and vascularization.
Implications:
- High-resolution sonography is an effective and non-invasive tool for diagnosing polyorchidism.
- This imaging technique can obviate the need for exploratory surgery in diagnosing supernumerary testes.
- Accurate sonographic diagnosis aids in appropriate patient management and follow-up.
