RESUMO
Reported is a fetal Dandy-Walker malformation that was strongly suspected in the first trimester through measurement of the brainstem-vermis (B-V) angle, which was found to be 119° on transvaginal ultrasound examination at 14 weeks and 2 days gestation. Definitive diagnosis of the Dandy-Walker malformation was made by magnetic resonance imaging following stillbirth. Ultrasound measurement of the B-V angle may be a useful index for prenatal diagnosis of Dandy-Walker anomalies during early pregnancy.

Uterine arteriovenous malformation (AVM) is a rare cause of abnormal uterine bleeding; nevertheless, it is a potentially life-threatening condition when the diagnosis is not made. We report a case of uterine AVM with a secondary uterine hematoma diagnosed 2 weeks after curettage due to spontaneous abortion. Ultrasound examination revealed a mixed echogenic mass of approximately 4 cm × 1.5 cm with no blood flow and an additional contiguous heterogeneous mass with turbulent blood flow depicted by color Doppler. Transvaginal sonohysterography enabled us to exclude residual chorionic tissues and to make precise diagnosis of uterine AVM with a secondary hematoma.

We experienced a case of uterine wall defect with amniocele in a primigravida woman without any history of uterine surgery. On admission due to acute abdominal pain at 32 weeks' gestation, an ultrasound examination showed a 9 × 7-cm sized echogenic cystic area in the Morrison pouch. Color Doppler revealed a flow from the uterus into the cystic area through a myometrial defect. During the operation, a 1-cm defect in the uterine myometrium was found on the right fundus. An intact amniotic sac was prolapsed into the abdominal cavity through the myometrial defect. This was an extremely rare case of unexplained uterine wall defect.
