[A rare case of acute scrotum. Thrombophlebitis from ectasia of the left pampiniforme plexus].

The acutely painful scrotum may be due to testicular torsion, twisted testicular appendages, twisted spermatic cord or epididymitis. Most rarely it occurs as a result of a testicular trauma, orchitis, idiopathic scrotal edema, idiopathic infarction of testis and vaginalis tunica or testicular neoplasm; a spontaneous thrombosis of the spermatic vein vessels is quite unusual. A rare case of thrombosis of a dilated pampiniform plexus which occurred in a 6 year-old child is reported and its clinical presentation, diagnosis and treatment is discussed. The difficulty in making such a diagnosis is stressed since thrombosis of the spermatic vein is quite a rare entity; a conservative approach is suggested as a treatment of choice whenever a definite diagnosis is made, otherwise surgical intervention (ligation of the spermatic vein, if necessary) is required in order to rule out any other urologic emergency.
