Scrotal Pearls and Pitfalls

Abstract

Scrotal symptoms including palpable mass or pain often bring men to medical attention. Ultrasound serves as an extension of the physical examination in these patients and, in most cases, allows definitive diagnosis. Although the diagnosis of malignancy is of greatest concern both to the patient and clinician, a number of benign scrotal pathologies exist and most have characteristic imaging features. Knowledge of these imaging findings can help the radiologist to confidently identify common benign scrotal conditions. Location and imaging characteristics of uncommon lesions help to establish a rational differential diagnosis and appropriate recommendations for patient management.

Abdominal Lymphangioma and Hemangioma in a Newborn

“…Etiology and pathogenesis of HLA are not elucidated in the literature. The coexistence of these two pathological entities may be related to abnormal development of the lymphatic structures during the embryonic period [10].…”

AIUM Practice Parameter for the Performance of Scrotal Ultrasound Examinations

“…Indications for scrotal ultrasound include but are not limited to 1,2 the following: Evaluation of scrotal pain, including but not limited to testicular trauma, ischemia/torsion, postsurgical pain, and infectious or inflammatory scrotal disease 3–10 Evaluation of a palpable inguinal, intrascrotal, or testicular mass 1,2,11–13 Evaluation of scrotal asymmetry, swelling, or enlargement 1,2,14–16 …”

The Rare, the Odd, and the Atypical

“…On ultrasound (US), testicular lipomatosis is characterized by multiple intratesticular echogenic lesions of varying size, typically 1 to 6 mm, that are randomly distributed throughout both testes and do not exhibit posterior acoustic shadowing 3 (Fig. 1A).…”
