title: Sonographic documentation of uterine retroversion mimicking uterine sacculation.
abstract: Uterine retroversion during the first trimester is quite common. However, as the uterus increases in size, self-correction usually occurs and the second trimester pregnant uterus becomes an abdominal organ. If anteversion does not occur, pelvic impaction will result. The prevalence of late first and early second trimester uterine impaction is approximately 1 in 3000 pregnancies. Our case documents sonographically the spontaneous resolution of a markedly retroverted uterus at 26 weeks' gestation.
