Objectives: To evaluate the clinical, ultrasonography signs and Doppler color in the diagnosis of the torsión of pedicle. Methods: Prospective observational study of cross-section included 22 patients over a period of three years, who attended with acute abdominal pain and presence of anexial cyst. With an age range between 22 and 58 years. Results: 22 patients, 9 had torsión of pedicle; triad classic showed a 55% sensitivity, specificity 46%, positive predictive value 42%, negative predictive value 60%. The direct sign of torsión of pedicleshowed a sensitivity of 78%, specificity 92%, positive predictive value 87%,negative predictive value of 86%. The absence of Doppler signal colorshowed a sensitivity of 100%, specificity of 69%, positive predictive value 69%, negative predictive value of 100%. The abdominal free liquid showed a variable result. Conclusions: The clinical suspicion is the first passage in the diagnosis; the finding of the direct sign of torsión was the one of greater value diagnosis; the finding of color Doppler signal in the wall of the cyst practically, discarded any possibility of torsion.
