Chorionic bump is a rare condition in the first trimester of pregnancy. It appears as a bulge from the choriodecidual surface into the gestational sac. So far, there have been no ultrasound or clinical markers that can predict a difference in outcomeWe report a case of a pregnant woman with history of infertility, diagnosed in the first trimester with a chorionic bump. It disappeared spontaneously at 23 weeks of gestation. The pregnancy went well and she delivered a healthy baby.The aetiology and clinical significance of the chorionic bump remains unclear...

Hypercalcemia due to primary hyperparathyroidism during pregnancy is a rare condition and associated with increased morbidity and mortality for the mother and the unborn child. Whereas parathyroidectomy is favored during the second trimester, no clear recommendations exist for its management during the third trimenon. We here report the case of a 26-year-old woman in the 29th week of her first pregnancy, who was admitted to our clinic with hypertension, intra-uterine growth retardation and polyhydramnios. Severe hypercalcemia due to primary hyperparathyroidism was diagnosed (total calcium 3...

Conjoined twinning occurs in 1/100 of monozygotic twins, 1/50,000 gestations and 1/250,000 live births. It is the consequence of a division event at the primitive streak stage of the human embryonic development, about 13-14 days after fertilisation, in monochorionic monoamniotic gestations. A healthy pregnant woman, Gravida 2 Para 1, was admitted into our Fetal Medicine Unit to perform the first trimester ultrasound. A diagnosis of conjoined parapagus twinning based on ultrasound features was made at 11 weeks of gestation, and the couple decided to terminate the pregnancy...

The study aimed to evaluate the effect of pregnancy on heart diameters and function in goats. Transthoracic echocardiography of 12 female dairy goats of two Polish regional breeds was performed. A Mindray M7 diagnostic ultrasound system with Phased Array transducer was used. Simultaneously, electrocardiography was recorded. All animals were examined four times - at mating season, at the end of the first trimester, at the end of the second trimester and just before kidding. Eleven measurements were taken each time: aortic and left atrial diameter (AoD and LAD), right and left ventricular internal diameter in diastole (RVIDd and LVIDd), left ventricular internal diameter in systole (LVIDs), inter-ventricular septum thickness in diastole and systole (IVSd and IVSd) and left ventricular posterior wall in diastole and systole (LVPWd and LVPWs), maximum left and right ventricular outflow tract velocity (RVOT Vmax and LVOT Vmax)...

Introduction: Before the advent of assisted reproductive technologies, the incidence of heterotopic pregnancy was estimated to be in 1 out of 30,000 pregnancies in the United States. With interstitial pregnancy comprising only 2.4% of ectopic pregnancies, spontaneous heterotopic interstitial pregnancies are exceedingly rare. Case: A 27-year-old pregnant woman (gravida 3 para 1011) with a history of one prior term vaginal delivery and a spontaneous abortion in the first trimester presented to the emergency department with abdominal pain and a positive home pregnancy test...

AIM: To develop a first-trimester or combined first- and second-trimester screening algorithm for the prediction of small-for-gestational age (SGA) and late growth-restriction (FGR). METHODS: This was a retrospective study of pregnant women with singleton pregnancy, who attended routine first- second- and third-trimester ultrasound scan. Late FGR was defined, at ≥32 weeks in the absence of congenital anomalies as, either (a) estimated fetal weight (EFW) or birthweight (BW) <3rd centile , OR (b) EFW<10th centile and either uterine artery mean PI >95th centile or cerebroplacental ratio (CPR) <5th centile...

Congenital aneurysms and diverticula of the heart are rare anomalies and their prenatal diagnosis is challenging. Fetuses with suspected cardiac aneurysms on ultrasound (US) screening should undergo targeted fetal echocardiography, postnatal imaging, and follow-ups. Herein, we describe the second trimester US scan and postnatal cardiac magnetic resonance imaging (MRI) findings of a baby girl with concurrent septal and right ventricular cardiac aneurysms. Other cardiac and extra-cardiac structures were normal...
