Brief Summary
Clinical diagnosis of adnexal torsion is difficult because the symptomatology is dominated by abrupt onset pelvic pain, an aspecific sign which does not allow a diagnosis of certainty to be made. To confirm the diagnosis, the reference examination is pelvic ultrasound with Doppler flow analysis. However, its intake is low, its sensitivity varies from 46 to 73% depending on the studies. Other imaging techniques have been considered, such as MRI, with a sensitivity far superior to ultrasound, but its difficult accessibility, in particular in the context of an emergency, makes it unusable in clinical practice. The use of ultrasound with the injection of an ultrasound contrast agent, strict intravascular, seems to be an interesting technique to assess the perfusion parameters of the ovary and improve the diagnostic sensitivity of the adnexal torsion. Its interest has already been demonstrated in the diagnosis of testicular torsion in animals but to date, no study has evaluated its contribution in adnexal torsion.
