    Reference ranges for fetal volumes in the late first trimester, obtained using 9-degree rotational steps
    Objectives: In the course of another study, we calculated fetal volume centile values for each week of gestation from 11 to 14 weeks using nine-degree rotation steps.

    Looking though the keyhole at Megacystis
    Megacystis is a sonographic feature of an abnormally large fetal bladder for gestational age. The incidence is estimated globally as 0.38% with predominantly male fetuses affected. Even with treatment options and early diagnosis this condition has a relatively poor prognosis.

    Sonographic soft markers in the second trimester: Subtle indicators or significant findings?
    Advances in ultrasound technology over recent times, mean that the once controversial area of aneuploidy detection is becoming a popular topic for sonographers worldwide. Improved resolutions from high end machines mean that very subtle anatomic variants may have a part to play in the detection of chromosomal abnormalities. When combined with laboratory testing and risk assessment tools, early detection of these soft markers can provide a rationale for the diagnosis and management of fetal chromosomal defects.

    Caesarean Scar Ectopic: sonographic findings and management dilemmas
    The last decade has seen an increase in caesarean section (CS) rates in Ireland and internationally with a concommitant rise in the incidence of caesarean scar ectopic. Greater awareness of the common sonographic presentations of caesarean scar ectopic at different gestational ages may improve detection rates and reduce morbidity (Timor-Tritsch et al, 2012). The prevalence of caesarean scar ectopics is thought to be 1 in 2000 pregnancies causing significant morbidity and mortality (Sieczko et al, 2014). Defined as implantation of the pregnancy within the scar, it is thought to occur due to a fistula devoloped between the scar and the endometrium.The potential for uterine rupture causing massive haemorrhage is caused by trophoblastic invasion from the implantation site without the supportive myometrium (Jungkman and Anderson, 2015). Four cases identifed in an Irish tertiary referal centre over 4 years demonstrate the differing presentations of caesarean scar ectopic and the management dilemmas discussed in the setting of Irish legislation in relation to termination of pregnancy.

    Scar Ectopic: A waiting game...?
    Caesarean scar ectopic pregnancy (CSEP) is a rare occurrence in pregnancy, it’s presentation warrants emergent care. While it is the rarest form of ectopic pregnancy, (1:1,800-1:2,216 of all pregnancies), the incidence is increasing (Rotas et al, 2006). This early study highlighted that the increase is most likely due to the growing number of caesareans being performed. In CSEP, the gestational sac (GS) is implanted within the myometrium of a previous caesarean section scar (Rana et al, 2013). This poster discusses a case where the patient initially presented to the Accident and Emergency Department (A+E), with lower abdominal pain. An overview of her case will be outlined, from initial assessment, diagnosis and management to complete resolution. This case highlights the integral role of the transvaginal ultrasound scan (TVS) in conjunction with serial biochemistry in the management of CSEP. Serial biochemistry involves monitoring the pregnancy hormone human chorionic gonadotrophin (hCG).
