To review how to perform color Doppler sonography (CDS) of acute scrotum To describe the sonographic findings of intravaginal torsion To learn to recognize the twisted spermatic cord To highlight the diagnostic pitfalls To provide prognostic criteria To discuss the other causes of acute scrotum  

1. CDS technique: comparative study of both testes and extratesticular structures 2. Testicular signs of torsion: absent or decreased blood flow, enlargement, abnormal echogenicity, heterogeneity, abnormal location 3. Extratesticular signs: abnormal epididymal head location, extratesticular mass of 12-33 mm in anteroposterior diameter connected to the inguinal cord 4. Diagnostic Pitfalls 7. Good prognostic signs: vascularized or iso-hyperechoic testis with mild enlargement 8. Signs of necrosis: heterogeneous or avascular testis with thickened hyperemic scrotal wall 9. Negative signs of torsion in spontaneous detorsion, epididymoorchitis and appendix torsion Intravaginal torsion is much more frequent in teenagers than in children. It is a surgical emergency requiring early diagnosis to avoid necrosis. In uncertain cases, CDS is helpful and can reduce needless surgery. Spiral twist detection is the only reliable sign of testicular torsion whatever its consequences for the testis. CDS may predict testis prognosis.
