title: [Torsion of the appendix testis].
abstract: The differential diagnosis of an acute scrotum includes spermatic cord torsion, torsion of a testicular appendage, torsion of spermatocele, epididymitis, orchitis, trauma, hernia, testicular segmental infraction and tumor. Among these, torsion of appendix testis could got dramatic improvement if accurately diagnosed and treated. 5 patients of torsion of appendix testis have been identified in our hospital in the recent 5 years. Ages ranged from 9 to 13 years old (mean age 11). The lesions were on the right side in 2 cases and left side in 3 cases. Duration of scrotal pain ranged from 2 to 7 days (mean of 4 days). The urine analyses were normal in all cases. The white blood counts were all within normal limits with mean of 5.72 x 10(3)/ul. No abnormality in passing urine or other infectious sign could be detected. Doppler ultrasonography or nuclear medicine testicular scan were performed selectively due to clinical availability. The result was equivocal and did not support a definite diagnosis. All 5 cases received surgical treatment. The necrotic testicular appendix was excised and reactive hydrocele treated. All the patients were discharged from the hospital the day after operation and recovered quickly. The pathological report revealed congestion and extensive hemorrhagic necrosis of the testicular appendix. Advances in technology have been helpful in improving the accuracy of diagnosis but technology is not infallible and an over reliance on it can also result in misdiagnosis. Various reports supporting the use of scrotal ultrasound in evaluating cases of acute scrotum pain. Ultrasonography has definitely helped in detecting scrotal pathology but its limitations need to be appreciated. Because of the difficulty of making an accurate diagnosis in acute scrotum, misdiagnosis and delayed operation offer result in disappointment of testis salvage rates. We have supported a policy of early scrotal exploration in any case suspicious of torsion of appendix testis.
