What is a nontender, fluid-filled scrotal mass overlying the testis called?

A nontender, fluid-filled scrotal mass overlying the testis is referred to as a hydrocele. A hydrocele is essentially a bag of fluid that surrounds the testis, which can occur due to various reasons, such as incomplete closure of the processus vaginalis or inflammation. Importantly, hydroceles are usually painless and do not cause significant discomfort, which differentiates them from other conditions affecting the scrotum.

In the case of a varicocele, it involves the enlargement of veins within the scrotum and may present as a "bag of worms" feeling, but it is not fluid-filled like a hydrocele. Epididymitis, on the other hand, is characterized by inflammation of the epididymis leading to pain and swelling; it is typically tender rather than nontender. Testicular torsion is a surgical emergency that presents with sudden onset of severe pain and swelling; it is not associated with a nontender scrotal mass and requires immediate intervention.

Understanding the unique characteristics of these conditions helps in accurate diagnosis and management in neonatal care. In this context, recognizing a hydrocele for its nontender and fluid-filled nature can guide healthcare professionals in providing appropriate reassurance and monitoring to the
