[Pelvic hydatid cyst: atypical ultrasonographic findings in one case (author's transl)].

The authors present one case of pelvic hydatid cyst scanned by ultrasound. This recent localisation of the hydatid disease permits the description of particular semeiological data. This aspect is not described in the literature concerning the cystic pathology of the pelvis, and can be evocative of an parasitic etiology.
