Abstract

Extratesticular lesions are common incidental findings at ultrasonography (US) among men and boys. Most lesions originate from or depend on the tunica vaginalis, a mesothelium-lined sac with a visceral layer and a parietal layer. The tunica vaginalis is formed when the superior portion of the processus vaginalis closes during embryologic development. Abnormal closure of the processus vaginalis leads to congenital anomalies of the tunica vaginalis, such as complete or partial patency of the processus vaginalis, spermatic cord hydrocele, and inguinoscrotal hernia. The proximity of the visceral layer to the testis explains the reactive involvement seen in epididymo-orchitis, with resultant pyocele or abscess formation. The tunica vaginalis also may be affected by inflammatory and traumatic disorders such as scrotal calculi, fibrous pseudotumor, or hematocele. These lesions manifest as solid or heterogeneous tumorlike masses. Lesions of mesothelial origin, such as adenomatoid tumor, tunica cyst, and mesothelioma, may involve the tunica vaginalis. Entrapped mesenchymal cells can lead to lipoma, leiomyoma, or sarcoma, although these tumors are uncommon in the tunica vaginalis. US is not useful for differentiating between benign and malignant tumors; however, some characteristic findings may help in planning the best surgical approach. Knowledge of the embryologic development, anatomic relationships, and pathologic disorders of the tunica vaginalis is essential to narrow the differential diagnosis of an extratesticular lesion. In most cases, US findings in combination with clinical assessment can indicate whether nonsurgical management or testis-sparing surgery is warranted.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-01:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 67.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 67 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 3.
  • The number of mentions on Wikipedia: 6 (Altmetric).
Continuing with the social impact of the work, it is important to emphasize that, due to its content, it can be assigned to the area of interest of ODS 3 - Good Health And Well-being, with a probability of 75% according to the mBERT algorithm developed by Aurora University.
