What is the classic description of varicocele?

The classic description of varicocele as a "bag of worms" refers to the appearance of dilated and tortuous veins in the scrotum, particularly in the pampiniform plexus. This description effectively conveys the abnormal, lumpy, and swollen state of the veins that can be palpated during a physical examination. In a varicocele, the veins become engorged due to impaired venous drainage, leading to a collection of veins that looks similar to a bag filled with worms. This visual analogy is widely recognized among medical professionals and serves as an important clinical cue in diagnosing the condition.

The other descriptions, while they may evoke certain imagery, do not accurately capture the specific appearance and clinical significance associated with varicocele. Thus, the "bag of worms" remains the most classic and widely accepted description in medical literature and practice.
