What is the best course of action for a reproductive-aged adult male with a history of hernia, presenting with heterogeneous epididymal parenchyma, anechoic cysts, punctate echogenicities suggestive of calcification, bilateral hydrocele, and varicocele, as well as a complex scrotal ultrasound findings?

Management of Complex Scrotal Ultrasound Findings in Reproductive-Aged Male

The most critical next step is to proceed with the recommended CT scan of the abdomen and pelvis with oral contrast to definitively characterize the large heterogeneous right scrotal mass (12 x 11.8 cm), as this finding—particularly with minimal color flow and no peristalsis in a patient with known hernia history—requires urgent evaluation to exclude incarcerated bowel, testicular malignancy, or other surgical emergencies. 1

Immediate Priority: The Large Right Scrotal Mass

The 12 x 11.8 cm heterogeneous echogenicity with minimal color flow is the most concerning finding requiring immediate attention:

• This mass is far too large to represent typical benign scrotal pathology and demands cross-sectional imaging to distinguish between incarcerated inguinal hernia contents (bowel, omentum), complex hydrocele with septations, or—critically—a large testicular neoplasm that may appear extratesticular 1

• The absence of visible peristalsis does NOT exclude incarcerated bowel, as ischemic or chronically incarcerated bowel may show no peristaltic activity, making CT with oral contrast essential for definitive diagnosis 1

• CT abdomen/pelvis with oral contrast will definitively identify bowel loops (if hernia-related), assess for testicular mass extension, evaluate retroperitoneal lymphadenopathy (if malignancy), and guide surgical planning 1

Secondary Findings Requiring Attention

Epididymal Abnormalities

The heterogeneous right epididymal parenchyma with punctate echogenicities and 0.6 x 0.7 cm anechoic cyst represents chronic epididymal changes:

• Punctate calcifications in the epididymis typically indicate prior inflammation or chronic epididymitis, which is benign and requires no specific intervention unless symptomatic 2, 3

• Epididymal cysts are extremely common benign findings seen in up to 30% of men and do not require treatment unless causing discomfort 4

• The heterogeneous parenchyma combined with calcifications suggests chronic inflammatory changes rather than acute epididymitis, which would show marked hyperemia on color Doppler 2

Bilateral Varicoceles

Both right and left varicoceles are documented:

• Varicoceles are present in 15% of the general male population and up to 40% of infertile men, representing the most common correctable cause of male infertility 5

• Right-sided varicocele warrants careful attention as isolated right varicocele can be associated with retroperitoneal pathology obstructing venous drainage, though bilateral varicoceles are typically benign 3, 5

• The planned CT scan will simultaneously evaluate for any retroperitoneal masses that could cause secondary right varicocele 3

Bilateral Hydroceles

Small bilateral hydroceles are noted:

• Small hydroceles are common reactive findings associated with varicoceles, epididymal inflammation, or testicular pathology 2, 4

• In young men, "complex hydrocele" appearance on ultrasound should raise suspicion for underlying testicular tumor, though the testes here are described as homogeneous without focal lesions 6

Testicular Size Assessment

Both testes measure within normal range (right: 3.9 x 1.8 x 2.9 cm; left: 4.1 x 2.1 x 3.2 cm):

• Using the Lambert formula (Length × Width × Height × 0.71), the right testis volume is approximately 14.5 ml and left is approximately 18.5 ml, both above the 12 ml threshold for atrophy 7

• Testicular volumes above 12 ml are generally considered normal and not associated with significant risk of impaired spermatogenesis or intratubular germ cell neoplasia 7, 8

• The homogeneous parenchyma with documented color flow in both testes is reassuring against testicular torsion or infarction 1

Clinical Algorithm for Management

Step 1: Urgent Imaging (Within 24-48 Hours)

• Obtain CT abdomen/pelvis with oral contrast to characterize the 12 cm right scrotal mass 1
• Specifically assess for: incarcerated hernia contents, testicular mass with extratesticular extension, retroperitoneal lymphadenopathy, and causes of secondary right varicocele 1

Step 2: Surgical Consultation

• If CT confirms incarcerated hernia: urgent surgical repair to prevent bowel ischemia 1
• If CT suggests testicular malignancy: immediate urology referral for tumor markers (AFP, β-hCG, LDH) and inguinal orchiectomy 1
• If CT shows benign findings: elective hernia repair can be scheduled 1

Step 3: Address Fertility Concerns (If Applicable)

• Given bilateral varicoceles, obtain semen analysis if the patient has fertility concerns or is attempting conception 5
• Varicocele repair improves semen parameters in 60-70% of men with clinical varicoceles and abnormal semen analysis 5
• Bilateral varicoceles can be addressed through single scrotal access if surgical intervention is indicated 9

Step 4: Routine Follow-Up for Benign Findings

• Epididymal calcifications and cysts require no specific follow-up unless symptomatic 3, 4
• Small hydroceles require no intervention unless progressive or symptomatic 4
• Teach testicular self-examination for early detection of any future masses 7

Critical Pitfalls to Avoid

• Do not dismiss the large scrotal mass as "just a hydrocele" without cross-sectional imaging—complex hydroceles in young men can mask testicular tumors 6

• Do not assume absence of peristalsis excludes hernia—ischemic bowel shows no peristalsis and requires emergency surgery 1

• Do not treat subclinical varicoceles found only on ultrasound—only palpable varicoceles with documented fertility impact benefit from repair 5

• Do not delay CT imaging—if this represents incarcerated bowel, delay increases risk of bowel necrosis and need for bowel resection 1
