Hypoechoic testicular lesions detected via ultrasound (US) in men with normal clinical exams are often malignant, frequently seminoma. Management requires careful histological diagnosis to ensure appropriate treatment for these impalpable tumors.

Area of Science:

  • Urology
  • Oncology
  • Diagnostic Imaging

Background:

  • Clinically impalpable testicular lesions pose diagnostic challenges.
  • Ultrasonography (US) is crucial for detecting subtle testicular abnormalities.
  • Differentiating benign from malignant impalpable lesions is critical for patient management.

Purpose of the Study:

  • To evaluate the significance of hypoechoic testicular lesions identified by US in the absence of palpable abnormalities.
  • To discuss the complexities in managing such cases.

Main Methods:

  • A retrospective analysis of four patients who underwent radical orchidectomy for US-detected hypoechoic testicular lesions.
  • Indications for US included scrotal discomfort, contralateral orchitis, and microlithiasis follow-up.

  • Lesion sizes ranged from 4-11 mm; tumor markers were normal.

    • Main Results:

    • Seminoma was diagnosed in three of the four testes, with one case showing multifocal disease.
    • Intratubular germ cell neoplasia was present in all seminoma cases.
    • One patient had a Leydig-cell tumor; all were staged as pT1.

    Conclusions:

    • Hypoechoic testicular lesions on US, even when impalpable, have a high likelihood of malignancy, particularly seminoma.
    • Management necessitates thorough histological evaluation to confirm diagnosis and guide treatment.
    • Prompt diagnosis and appropriate histological assessment are vital for impalpable testicular tumors.
