Nevertheless, it offers a valuable context for reflecting on how surveillance strategies can evolve in such congenital anomalies. The decision to initiate empirical antibiotics and NSAIDs is clinically sound, yet future protocols might consider refining indications for antimicrobial use based on inflammatory markers or seminal plasma analysis, tools that can differentiate infectious from obstructive discomfort, especially in the absence of overt urinary tract infection [<span>2, 3</span>].</p><p>Another area worth discussing lies in the parameters guiding longitudinal follow-up.

However, recent studies suggest that seminal vesicle cysts with high proteinaceous content may benefit from biochemical analysis if aspiration is indicated in future cases [<span>4</span>]. Even when surgery is deferred, evolving imaging markers, such as cyst wall thickening or atypical signal patterns, might be integrated into future conservative frameworks to ensure safety.</p><p>This case demonstrates commendable clarity in the approach and contributes to an underrepresented segment of the urological literature.
