[Adnexal torsion with hemorrhagic infarct in early pregnancy. Diagnosis by color-coded vaginal Doppler sonography].

A 25 year-old woman presented with left lower quadrant pain in the 11th week of gestation. Transvaginal sonography showed a 7 x 8 x 5 cm cystic-solid mass with an adjacent 9 mm echogenic structure on the left side corresponding to the adnexal stalk. Color Doppler sonography revealed the absence of central or peripheral flow within the mass suggestive of adnexal torsion and subsequent infarction. Laparoscopic detorsion of the left adnexa was not followed by restoration of perfusion ad a left adnexectomy was performed. Transvaginal color Doppler sonography is useful for preoperative diagnosis of adnexal torsion.
