Cervical pregnancy is an uncommon ectopic pregnancy that accounts for approximately

Preeclampsia is uncommon prior to 24 weeks gestation and has been associated with partial and complete hydatidiform moles. We present an unusual case in which a patient was diagnosed with preeclampsia at 17 weeks gestation. Ultrasound findings were consistent with a partial hydatidiform mole. Within 24 hours of the onset of symptoms, the patient developed severe hemolysis, elevated liver enzymes, and low platelet count syndrome, with a platelet count of 20 x 10 (9) cells/L. Termination of pregnancy was performed with rapid resolution of signs, symptoms, and laboratory abnormalities. Triploid 69,XXY was confirmed at karyotype analysis. This case demonstrates the acuteness in which life-threatening maternal conditions can arise with this uncommon complication of pregnancy, and the importance of correct identification of the characteristic ultrasonographic findings associated with a partial hydatidiform mole.

We present an unusual case in which a 23-year-old nulliparous patient was noted to have bilateral multicystic adnexal masses at 21 weeks gestation. Subsequent severe nausea, vomiting, and hyperglycemia with a serum glucose level of 450 mg/dL led to the diagnosis of gestational diabetes. Gradual development of marked maternal virilization ensued and was associated with a serum testosterone level of 4030 ng/mL (free testosterone level of 224 pg/mL), with normal serum dehydroepiandrostendione, estriol, and cortisol levels, leading to the diagnosis of hyperreactio luteinalis. Following vaginal delivery at 38 weeks gestation, gradual and complete spontaneous resolution of signs, symptoms, adnexal masses, diabetes, and testosterone levels were documented.

An increased incidence of thrombotic thrombocytopenic purpura has been reported among human immunodeficiency virus-infected patients or those with acquired immunodeficiency syndrome (AIDS). Despite this association, hitherto only a single case of thrombotic thrombocytopenic purpura has been reported in an HIV-infected patient during pregnancy. We describe a young multiparous patient with long-standing AIDS who presented with lower abdominal pain. Following findings of thrombocytopenia, microangiopathic hemolytic anemia, renal failure, low-grade fever, and mental status changes, thrombotic thrombocytopenic purpura was diagnosed after initially considering the diagnosis of severe preeclampsia, and the patient was delivered by cesarean section. The patient required multiple plasma exchanges during a protracted postpartum course, and was discharged in good health. This first report of thrombotic thrombocytopenic purpura and AIDS in pregnancy demonstrates that when encountering preeclampsia in patients with AIDS, thrombotic microangiopathy should be strongly considered. In addition, these patients may exhibit an attenuated response to plasma exchange therapy and despite previous reports in nonobstetric patients, a favorable outcome is attainable in these critically ill patients.

Uterine contraction-associated accelerations of the maternal heart rate are considered to reflect both a transient contraction-related increase in cardiac output and endogenous catecholamine secretion. Uterine contraction-associated decelerations of the maternal heart rate are rare and remain unexplained. A young multiparous patient with systemic lupus erythematosus (postrenal transplant for lupus nephropathy-related renal failure) presented in early labor at 39 weeks gestation, prior to elective repeat cesarean section. Intrapartum continuous maternal heart rate monitoring demonstrated repetitive uterine contraction associated decelerations of the maternal heart rate of 60 beats per minute, each lasting 2 minutes, simulating nonreassuring fetal status. Simultaneously depicted fetal heart rate was reassuring. This case demonstrates an unusual marked early intrapartum affect of uterine contractions upon the maternal heart rate. In addition, this case illustrates the potentially dangerous similarity of an intrapartum maternal heart rate to an abnormal fetal heart rate pattern, and emphasizes the importance of correct identification of the maternal and fetal heart rates, respectively.

The cavum septum pellucidum is a fluid-filled cavity located between the membranes of the septi pellucidi, which should always be visualized sonographically in normal fetuses between 18 and 37 weeks gestation and in approximately 50% of term infants. The cavum vergae, a cavity within the septum pellucidum, is located posterior to an arbitrary vertical plane formed by the columns of the fornix. We present a case in which markedly dilated cavum septum pellucidum et vergae noted at 29 weeks gestation was associated with midgut malrotation and volvulus, and review the literature pertaining to this unusual prenatal ultrasonographic diagnosis.
