Summary
Intratesticular varicocele, a rare condition affecting less than 2% of symptomatic men, presents with characteristic sonographic features. This study details its appearance and occurrence using conventional and Doppler sonography.
Area of Science:
- Radiology
- Urology
- Medical Imaging
Background:
- Intratesticular varicocele is a rare vascular anomaly within the testis.
- Understanding its sonographic characteristics is crucial for accurate diagnosis.
Purpose of the Study:
- To describe the conventional and Doppler sonographic appearances of intratesticular varicoceles.
- To determine the incidence of intratesticular varicoceles.
Main Methods:
- Conventional and Doppler sonography were performed on 1040 men with testicular issues.
- Eighteen patients diagnosed with intratesticular varicocele underwent detailed sonographic and Doppler examination.
Main Results:
- Intratesticular varicocele was identified in 1.7% of patients (18/1040).
- The condition was bilateral in 7 patients and unilateral in 11, with 48% affecting the right side.
- Sonographic findings included tubular or oval dilated veins, with diameters ranging from 2-8 mm and a mean venous flow velocity of 2.8 cm/sec.
Conclusions:
- Intratesticular varicocele is an uncommon finding, observed in less than 2% of symptomatic men.
- Characteristic sonographic features include dilated intratesticular veins near the mediastinum testis.
- This study noted variations such as oval shapes, increased bilateral occurrences, and isolated right-sided presentations compared to prior reports.
