Based on physical examination alone, it is often difficult to decide whether a palpable scrotal swelling arises from testicle itself or from extra testicular elements in scrotum. Aim of the study: To evaluate the causes of scrotal swellings in different age groups using sonography.
Patients and method:One hundred patients, with age ranging between1-77years(mean age of 31 +/- 7 years), presented with scrotal swellings were examined by real-time ultrasound during the period from October 2011 to April 2012 in Al-Sadir Medical City at Al-Najaf government-Iraq
Results: Sonographic examination was normal (could not detect any lesion) in 7 patients (7%). The commonest sonographic finding was hydrocele (33.1%) while the next common findings were varicocele (20.3%) and epididymal cysts (14.4%). Inflammatory causes were detected in 14 patients (11.8%). Of the 8 (6.7%) patients with scrotal trauma, 5 cases showed features of hematocele and 3 cases extra-testicular hematoma. Least sonographic findings were testicular torsion, scrotal hernia and solid intratesticular mass (2.6% for each). Most of scrotal swellings were unilateral (right more than left) and 8% showed contralateral incidental findings.
Conclusion: Majority of causes of scrotal swellings were benign with the hydrocele being the commonest cause among all age groups. The least common causes of scrotal swellings were scrotal mass, hernia and testicular torsion. Although most of causes of scrotal swellings were benign, some were serious requiring urgent intervention, particularly testicular torsion, necessitating no delay in ultrasound examination for evaluation of patients with acute scrotal pain and swelling. To overcome limitations of this study, future study encompassing larger sample, including emergency cases, is recommended.
