[Semeiologic study of 50 ultrasonographied ectopic pregnancies (author's transl)].

Echographic changes in ectopic pregnancy can affect uterus, annexes and cul-de-sac of Douglas. They are inconstant and quite variable according to the anatomic stage. Echographic aspects of 50 proved ectopic pregnancies and their frequency are reported. The echographic signs are then evaluated according to their viability and possible errors (differential diagnosis).
