Acute scrotal pain in children requires prompt differentiation between inflammation and surgical emergencies. The paper reports the case of a 4-year-old boy with acute epididymitis that progressed to severe pachivaginalitis despite treatment. The inflammatory response led to epididymal ischemia and testicular hypoperfusion due to increased intravaginal pressure and impaired venous drainage. Though rare (1-2% of cases), this complication may mimic testicular torsion. In such evolving clinical scenarios, surgical exploration is essential to confirm the diagnosis and prevent permanent gonadal damage
