Both pregnancies associated with trisomy 13 were terminated abroad. In a large series of 38 fetuses with holoprosencephaly undergoing second‐ and third‐trimester karyotyping, 11 (29%) had an abnormal karyotype, 8 with trisomy 13 and 3 with other chromosomal defects.11 In another study of 30 fetuses with holoprosencephaly, 11 (37%) had chromosomal abnormalities, 8 of which involved chromosome 13.2 Conversely, of 46 cases of trisomy 13 diagnosed as part of a large multicentric first‐trimester sonographic screening study involving 100,311 singleton pregnancies with live fetuses, 11 (24%) had holoprosencephaly at the time of nuchal translucency measurement.12 Later on in pregnancy, when a thorough examination of the fetal brain is more plausible, detection of holoprosencephaly in fetuses with trisomy 13 is higher. According to a previous study, the cranium, thalamus, choroid plexus, and lateral ventricles can be visualized sonographically in 90% of cases at 11 weeks and in virtually all cases between 12 and 14 weeks.15 The choroid plexuses of the lateral ventricles are very prominent organs during this developmental period. Fetal MRI may be useful for confirmation of diagnosis in cases of suspected lobar holoprosencephaly. For a general discussion of epidemiology, clinical presentation and pathology, please refer to the article on holoprosencephaly (HPE). 10 Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Holoprosencephaly.

Abstract Holoprosencephaly (HPE) is a heterogeneous central nervous system (CNS) anomaly that results from a primary defect in induction and patterning of the rostral neural tube (basal forebrain), leading to varying degrees of incomplete separation of the cerebral hemispheres and facial anomalies. Crossref Holoprosencephaly, Atlas of Genetic Diagnosis and Counseling, 10.1007/978-1-60327 … Nail Bulakbasi, Osman Cancuri, Murat Kocaoğlu, The middle interhemispheric variant of holoprosencephaly: magnetic resonance and diffusion tensor imaging findings, The British Journal of Radiology, 10.1259/bjr.20160115, 89, 1063, (20160115), (2016). Holoprosencephaly (HPE) is a complex brain malformation resulting from incomplete cleavage of the prosencephalon, occurring between the 18th and the 28th day of gestation and affecting both the forebrain and the face. As with all types of holoprosencephaly, it is a rare congenital brain malformation in which there is failure of complete separation of the two hemispheres (which usually occurs around the 4th to 6th gestational weeks) and failure of transverse cleavage into the diencephalon and telencephalon. The basic structure of the cerebral hemispheres is lost, with variable amounts of residual cortex. Radiology. Foetuses who survive during intrauterine life are born with varying grades of brain and facial deformities. Disorders of Ventral Induction/Spectrum of Holoprosencephaly. The presence of large dorsal cysts, hydrocephalus, or midline craniofacial defects may provide clues that eventually lead to the recognition of the associated HPE. Fig. Fowlie A, Constantine G.

Informa HealthCare. Prenatal detection of holoprosencephaly has improved in the last 20 years. Lobar holoprosencephaly - Holoprosencephaly results from abnormal separation of forebrain (prosencephalon) structures during embryologic development While holoprosencephaly exists on a continuous spectrum of severity, there are several identifiable patterns along the spectrum, including: Alobar holoprosencephaly - Most severe form. Semin Ultrasound CT MR 2011;32(3):167–188. On antenatal ultrasound, there may be also evidence of polyhydramnios, a secondary feature due to impaired fetal swallowing. Radiology Matters: 3D Printing Is Bridging the Gap Between Radiology and Surgery The Ubiquity of AI at RSNA 2019 The integration of artificially intelligent technologies with breast imaging Holoprosencephaly (HPE) is a cephalic disorder in which the prosencephalon (the forebrain of the embryo) fails to develop into two hemispheres.Normally, the forebrain is formed and the face begins to develop in the fifth and sixth weeks of human pregnancy.The condition also occurs in other species. Holoprosencephaly is typically detected during a routine ultrasound exam. Images 1, 2: Fetal face by ultrasound (coronal and axial - 18 weeks) shows small head and protuberant orbits. Introduction Three-dimensional inversion rendering in the first- and early second-trimester fetal brain: its use in holoprosencephaly. Churchill Livingstone 1993; 292-294. Although the prenatal diagnosis of holoprosencephaly in the first trimester has been reported by several authors,710 to our knowledge, no reports on the systematic evaluation of the choroid plexuses for the screening of holoprosencephaly have been described thus far.

This study confirms previous reports that the prenatal sonographic diagnosis of holoprosencephaly is feasible in the first trimester.710 Moreover, we have documented the value of systematic visualization of the cross section of the fetal brain in the early detection of this condition. As part of our routine examination of the fetal anatomy in fetuses at 11 to 14 weeks' gestation, the butterfly sign was consistently looked for in our study. Haber HP, Stern M. Intestinal ultrasonography in children and young adults: bowel wall thickness is age dependent. Hydranencephaly is thought to arise from bilateral internal carotid … Indeed, 2 cases of holoprosencephaly in our series were detected in women originally requesting nuchal translucency screening. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Lobar Holoprosencephaly There were 3 cases in which the butterfly sign was not identified. As with most cerebral structural congenital abnormalities, alobar holoprosencephaly is visible on all modalities, but in general is identified on antenatal ultrasound (if performed), and best characterized by MRI. However, it may present in neonates with seizures, respiratory failure, flaccidity or decerebrate posturing with a vegetative state 5.

Ultrasound is a good modality for prenatal diagnosis of holoprosencephaly that is frequently associated with midline face deformity such as cleft lip and palate. However, the inability to identify the normal morphologic characteristics of the choroid plexuses could be a prominent feature in other pathologic conditions, such as the acrania/anencephaly sequence, posterior fossa cysts (Dandy‐Walker malformation), and large cephaloceles. Systematic identification of the butterfly sign at the time of sonographic assessment of nuchal translucency provides a valuable tool for the early screening of holoprosencephaly. Embryopathologic and ultrasound findings are reported in five cases of alobar holoprosencephaly that were diagnosed prenatally, two cases as early as 23 menstrual weeks. Methods.

In the other, the diagnosis was incidentally made during sonographic evaluation of the fetal anatomy before CVS. The etiology of otocephaly is poorly understood and has never been reported in a fetus with Trisomy 18. Holoprosencephaly radiology discussion including radiology cases. Case 2: cross‐sectional view of the fetal brain in a fetus with trisomy 13 at 12 weeks 4 days showing the absence of the butterfly sign. Early imaging and diagnosis helps in deciding the outcome of the ongoing pregnancy. Several authors have studied the association between holoprosencephaly and chromosomal abnormalities, particularly trisomy 13.

This feature is not present in first‐trimester fetuses with holoprosencephaly, however, because that condition is associated with severe distortion of the lateral ventricles and choroid plexuses. e amniotic uid around the fetus is normal in quantity. Radiographic features As will most cerebral structural congenital abnormalities, lobar HPE is visible on all modalities, but in general is identified on antenatal ultrasound, and best characterized by MRI. V Disorders of prosencephalic development. American Journal of Obstetrics and Gynecology. holoprosencephaly spectrum. Among them, early prenatal diagnosis of holoprosencephaly is a desirable clinical goal because this condition is associated with several chromosomal defects, mainly trisomy 13, trisomy 18, and triploidy.1 Even in fetuses with a normal karyotype, the detection of holoprosencephaly is important because this major brain anomaly is associated with an almost uniformly lethal outcome or, in the few survivors, with profound neurodevelopmental delay. Ultrasonography revealed a live fetus of 17 weeks with absent falx, fused thalami, monoventricle, proboscis, and cyclopia. Fig. Three distinct forms are noted: Alobar – monoventricle, fused thalami, semilobar with partial segmentation of ventricles and thalami and alobar with absent septum pellucidum, otherwise normal thalami and ventricles. Holoprosencephaly is a severe brain anomaly characterized by different degrees of fusion of the lateral ventricles resulting from failure of the prosencephalon to cleave during early embryogenesis. The outcome of affected infants remains uncertain, but neurological impairment occurs frequently. A total of 378 consecutive pregnancies undergoing chorionic villus sampling between 11 and 14 weeks' gestation were scanned before the procedure, following the recommendations of the Fetal Medicine Foundation (London, England).

Focused examination of the fetal brain in these cases showed the characteristic intracranial sonographic findings associated with holoprosencephaly, including a monoventricular cavity with an absent midline and fused thalami. In none of the cases was it possible to identify the “butterfly” sign (Figures 2 and 3). Radiology. A cross‐sectional view of the fetal brain, including the visualization of both choroid plexuses (the “butterfly” sign), was obtained in all cases. These included measurements of the crown‐rump length and nuchal translucency thickness, and assessment of the fetal anatomy looking for major structural defects.4,5 Evaluation of the brain included a cross‐sectional view of the fetal head, which in normal circumstances shows 2 paired echogenic structures filling most of the lateral ventricles, corresponding to the choroid plexuses. During the study period, 378 women considered at risk for chromosomal defects underwent first‐trimester CVS at a median gestational age of 12 weeks (range, 11–14 weeks). Alobar holoprosencephaly is a subtype of holoprosencephaly and is the most severe of the classical three subtypes, with both semilobar and lobar holoprosencephaly having less severe clinical manifestations.

Holoprosencephaly is a severe brain malformation caused by abnormal separation of the forebrain, a process that is normally completed by the 5th week of gestation (3). Holoprosencephaly refers to a spectrum of craniofacial malformations including cyclopia, ethmocephaly, cebocephaly, and premaxillary agenesis. AJNR Am J Neuroradiol 2002;23(1):151–156. Note the hypotelorism. The first-trimester ultrasound can detect alobar HPE but may be much less sensitive in detecting milder cases. In all cases, sonography was performed before the procedure, following the recommendations of the Fetal Medicine Foundation (London, England). An antenatal ultrasound study, at 32 weeks pregnancy, raised the suspicion of a brain malformation, but it was suboptimal due to maternal habitus. In addition to facial anomalies, anomalies of the spine and extremities are frequently associated with it and one must look for them, such as meningomyelocoele and limb abnormalities. The pregnancy miscarried at 23 weeks. Conclusions. Modern ultrasound imaging devices have increasingly allowed sophisticated prenatal diagnoses of fetal disorders. Indeed, a series of 15 fetuses with trisomy 13 scanned at 16 to 22 weeks' gestation showed that 7 (47%) had holoprosencephaly.13 In another series involving 33 fetuses with trisomy 13 scanned in the second and third trimesters, 13 (39%) had holoprosencephaly.14 In our series, 3 cases of holoprosencephaly were detected in the first trimester, and all were associated with abnormalities of chromosome 13: trisomy 13 in 2 and a ring chromosome 13 in the other.
