Although rare in absolute terms, holoprosencephaly is the most common brain malformation and is seen in 1 per 10,000-16,000 live births 3,9. Mutations in eight different genes are associated with holoprosencephaly (SHH, PTCH, SIX3, SL12, ZIC2, TGIF, TDGF1, and FAST1). Holoprosencephaly (HPE) is a rare congenital brain malformation resulting from incomplete separation of the two hemispheres. 2002;23 (1): 151-6. Alobar and lobar holoprosencephaly are associated with microcephaly and midfacial defects in 80% of cases. Radiographics. The middle interhemispheric variant of holoprosencephaly.

Anencephalic fetus at 18 weeks' gestation with a single nostril and abnormal orbit and eye anlagen as part of the HPE spectrum. Entezami M, Albig M, Knoll U et-al. Mcgahan JP, Nyberg DA, Mack LA. Classically three subtypes have been recognized, however additional entities are now included in the spectrum of the disease. First-trimester ultrasound diagnosis of holoprosencephaly: three case reports. It is usually obvious at birth even if antenatal diagnosis has not been made, due to associated midline facial anomalies including 3: Additionally, these children also have systemic problems, with poor feeding, hypothalamic/pituitary dysfunction and developmental delay 3. There may be recurrence risk for ~6% with non-chromosomal sporadic HPE. Invasive testing for karyotyping and array. Birth Defects Res. 1 In the case reported here, however, a relatively large anechoic area in the anterior aspect of the fetal brain was evident. Ultrasound diagnosis: Ultrasound diagnosis is made usually in the late second and third trimesters. 21 (2):163-169. . In alobar holoprosencephaly, the thalami are fused and there is a single large posteriorly located ventricle. Ultrasound may also show a snake under the skull sign in some situations. 2019 May 2. Case 6: Alobar holoprosencephaly - prenatal ultrasound 1st trimester, solitary median maxillary central incisor, lissencephaly type I: subcortical band heterotopia spectrum, mild malformations of cortical development. Home / Ultrasound Cases / Congenital Anomalies / Holoprosencephaly / What is Holoprosencephaly? Deer E, Nelson C, Moore K, Kennedy A. OP14.04: fused fornices—CNS findings and outcome in 30 fetal cases. Cohen MM. Unable to process the form. Abstract Orbital defects are rarely diagnosed in the fetus. However, these anomalies are highly associated with chromosomal and nonchromosomal defects. As with most cerebral structural congenital abnormalities, holoprosencephaly is visible on all modalities, but in general is identified on antenatal ultrasound, and best characterized by MRI. 2015;35 (1): 275-90. with normal to simplified cortical pattern, microcephaly with extensive polymicrogyria, malformations secondary to inborn errors of metabolism, mitochondrial and pyruvate metabolic disorders, cerebellar hypoplasias, not otherwise specified, focal cerebellar cortical dysplasias/heterotopia, lissencephaly with agenesis of corpus callosum and cerebellar dysplasia, associated with diffuse cerebral polymicrogyria. The Fetal Medicine Unit database, the North East London Regional Cytogenetics Laboratory, and the Department of Clinical Genetics database at Great Ormond Street Hospital were searched using the terms holoprosencephaly, trisomy 13, trisomy 18, and facial cleft, and case notes were examined to con… Holoprosencephaly can be diagnosed even in the first trimester after 11–12 weeks. Delivery: Standard obstetric care and delivery. Some non-craniofacial anomalies are also associated, such as genital defects, polydactyly, vertebral defects, limb reduction defects, and transposition of the great arteries 9. Winter TC, Kennedy AM, Woodward PJ. Takanashi J, Barkovich AJ, Clegg NJ et-al. Ultrasound Obstet Gynecol 1999;13:356-359.2 ; Peebles DM. Environmental factors such as maternal diabetes mellitus, alcohol use, and retinoic acid have been implicated in the pathogenesis. In some cases, it can potentially identify affected fetuses in the first trimester. So, routine prenatal ultrasound should be carried out in all patients during this period. The fundamental problem is a failure of the developing brain to divide into left and right halves (which normally occurring at the end of the 5th week of gestation). Ultrasound is a good modality for prenatal diagnosis of holoprosencephaly that is frequently associated with midline face deformity such as cleft lip and palate. Below are brief descriptions of the three main types. Crossref, Medline, Google Scholar; 44. The value of sonography in early pregnancy for the detection of fetal abnormalities in an unselected population. May 26, 2017 - This Pin was discovered by Andrea Garnica. Follow up: If pregnancy continues, follow-up should be standard. We present three cases of fetal holoprosencephaly diagnosed by transabdominal and transvaginal ultrasound examinations at 10 and 13 weeks' gestation. The fetal brain is almost completely divided into two distinct hemispheres except for a variable degree of fusion at the level of the cingulate gyrus and frontal horns of the lateral ventricle. Extracerebral defects are particularly common in fetuses with trisomies 13 and 18 and those with genetic syndromes. Nyberg DA, Mack LA, Bronstein A et-al. 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. For more details see the article on lobar holoprosencephaly. The basic structure of the cerebral lobes are present but are fused most commonly anteriorly and at the thalami. Lobar Holoprosencephaly. Fetal MRI may be useful for confirmation of diagnosis in cases of suspected lobar holoprosencephaly. Holoprosencephaly: clinical, anatomic, and molecular dimensions. 2007;2 (1): 8. Between 1990 and 2005, a collective of 51 fetuses with tentative ultrasound diagnosis of HPE was recruited at two tertiary referral centers for prenatal ultrasound diagnostics via the Pia Fetal Database (GE Medical Systems, Webling, Germany). There may be hypoplasia or absence of the corpus callosum. Below are brief descriptions of the three main types. A Short Explanation into the Disorder of Holoprosencephaly (HPE) A Short Explanation into the Disorder of ... Fetal CNS Live Ultrasound Scan - Duration: 21:56. Ultrasound Obstet Gynecol 2011;38(suppl 1):95. Crossref, Medline, Google Scholar; 34 Carvalho MHB, Brizot ML, Lopes LM, Chiba CH, Miyadahira S, Zugaib M. Detection of fetal structural abnormalities at the 11–14 week ultrasound scan. Extracerebral defects are particularly common in fetuses with trisomies 13 and 18 and those with genetic syndromes. As with most cerebral structural congenital abnormalities, holoprosencephaly is visible on all modalities, but in general is identified on antenatal ultrasound, and best characterized by MRI. Most commonly associated with facial abnormalities such as cyclopia, ethmocephaly, cebocephaly, and median cleft lip. Holoprosencephaly: prenatal sonographic diagnosis. 1 This condition is invariably associated with a wide range of midfacial defects ranging from a single incisor to cyclopia. Lobar: life expectancy may be normal but usually with severe developmental delay and visual impairment. Alobar holoprosencephaly, mobile proboscis and trisomy 13 in a fetus with maternal gestational diabetes mellitus: A 2D ultrasound diagnosis and review of the literature Article Jun 2007 A detailed family history should be obtained. This is one of a number of legislative requirements that we must adhere to and as part of the service that you receive from us these requirements are built into our systems and processes. All kinds of holoprosencephaly can be diagnosed by ultrasound. Note should be made that these are along a spectrum and as such, some patients can be on the border between two types. Ultrasound School Pregnancy Ultrasound Fetal Abnormalities Ultrasound Sonography Ultrasound Technician Medical Coding Medical Information Pediatrics Cases An antenatal ultrasound study, at 32 weeks pregnancy, raised the suspicion of a brain malformation, but it was suboptimal due to maternal habitus. There was no family history of birth defects. Part A Clin. For more details see the article on alobar holoprosencephaly. 2. The early embryonic occurrence may be even higher but may not be detected due to most fetuses aborting in early gestation. (2003) ISBN:1588902129.
