Unusual maternal vasculature in the placental periphery leading to the diagnosis of abdominal pregnancy at 25 weeks' gestation.

Abdominal pregnancy is a rare condition in which the fetus and placenta are located within the peritoneal cavity. Sonographic findings include visualization of the fetus separate from the uterus, failure to visualize the uterine wall between the fetus and urinary bladder, close approximation of fetal parts to the maternal abdominal wall, eccentric position or abnormal fetal attitude, and visualization of extrauterine placental tissue. We present an unusual case in which mid-trimester transabdominal color Doppler sonographic findings depicted unusual maternal vasculature in the placental periphery leading to the diagnosis of abdominal pregnancy.

Transperineal sonography of a large vulvar hematoma following blunt perineal trauma.

Vulvar hematomas may result from puerperal or nonpuerperal-related trauma. These perineal injuries, especially the puerperal type, may be life-threatening and require surgical exploration, evacuation, and hemostasis. In the absence of acute hematoma expansion, expectant management may suffice.

Do serum beta-human chorionic gonadotropin levels on day 4 following methotrexate treatment of patients with ectopic pregnancy predict successful single-dose therapy?

The purpose of this study is to assess whether serum beta-human chorionic gonadotropin (beta-hCG) levels on day 4 following methotrexate (MTX) treatment in patients with ectopic pregnancy predict successful single-dose therapy or the need for subsequent surgical intervention. Retrospective analysis of patients with ectopic pregnancies treated with MTX (50 mg/m (2)) was conducted. Inclusion criteria for MTX management were serum beta-hCG < 15,000 mU/mL, absent fetal cardiac activity, ultrasonographic gestational sac < 3.
