ALOBAR HOLOPROSENCEPHALY This is the most severe form in which the prosencephalon fails to divide. In the alobar and semilobar forms of holoprosencephaly, prenatal diagnosis using ultrasound is well established 1. The early embryonic occurrence may be even higher but may not be detected due to most fetuses aborting in early gestation. It is intermediate in severity, being worse than lobar holoprosencephaly and better than alobar holoprosencephaly. Holoprosencephaly (HPE) is the commonest congenital brain malformation and indicates absent or incomplete midline cleavage of the brain. "boomerang" configuration of the brain (peripheral rim of - Alobar or Semilobar holoprosencephaly For a general discussion of epidemiology, clinical presentation and pathology, please refer to the article on holoprosencephaly (HPE). Single primitive ventricle (holoventricle) with a large dorsal cyst. 05, American Journal of Medical Genetics Part C: Seminars in Medical Genetics, Vol. Holoprosencephaly may be associated to other midline defects and may be part of an aneuploidy such a trisomy 13 (Patau's syndrome). For a general discussion of epidemiology, clinical presentation, and pathology, please refer to the main article on holoprosencephaly. Alobar holoprosencephaly . Extracerebral defects are particularly common in fetuses with trisomies 13 and 18 and those with genetic syndromes. The prenatal sonographic diagnosis of alobar holoprosencephaly was first described in 1984. 12, No. The alobar holoprosencephaly occur in about 0.6–1.9 of 10.000 deliveries. Most commonly associated with facial abnormalities such as cyclopia, ethmocephaly, cebocephaly, and median cleft lip. - cortex covers, Cup configuration = To view detailed video clip of alobar holoprosencephaly please visit www.ultrasoundlink.net. However, the diagnosis of lobar holoprosencephaly is difficult, as a distinct interhemispheric fissure is present. Holoprosencephaly is a rare intracranial abnormality arising from failure of the prosencephalon to cleave during early embryonic life, which results in different degrees of lateral ventricular fusion and facial defects. Among them, 30 cases (1.7%) with holoprosencephaly were prenatally identified and described. Investigations: Detailed ultrasound examination, including neurosonography. Holoprosencephaly can sometimes be detected prenatally through ultrasound or MRI, though mild forms may not be reliably detected prenatally. The alobar form of holoprosencephaly, which is the most severe form, has the worst prognosis and most children do not survive beyond six months. Single primitive ventricle (holoventricle) with a large dorsal cyst. more cortex present, Ball configuration = Blaas HG(1), Eik-Nes SH, Vainio T, Isaksen CV. 2, 1 January 2002 | Prenatal Diagnosis, Vol. At 25-week gestation Alobar Holoprosencephaly was detected by ultrasonography. Holoprosencephaly is typically detected during a routine ultrasound exam. 22, No. Other less common facial anomalies include micrognathia, Achiron et al (1995) described one case at 10 weeks and 4 days as well as Wong (1999), Hong Soo Wong (1999) and Turner (1999). The holosphere is diagnostic of alobar holoprosencephaly. ULTRASOUND: Interhemispheric fissure absent. 1, No. 16, No. For more details see the article on alobar holoprosencephaly. The intact falx in hydranencephaly differentiates it from alobar holoprosencephaly. Alobar holoprosencephaly is a subtype of holoprosencephaly (HPE), and is the most severe of the classical three subtypes, with both semilobar and lobar holoprosencephaly having less severe clinical manifestations. Hydranencephaly is thought to arise from bilateral internal carotid … This results in a single primitive ventricle, absent olfactory bulbs and optic tracts and severe developmental abnormalities. 31, No. trigonocephaly, microphthalmia Holoprosencephaly can result in the way the face and head of the baby develops at the time of birth. Suseela Vavilala, MD, Sarada, MD, Bindu, MD . - Semilobar or Lobar holoprosencephaly. This was done to confirm 22 22 the diagnosis by ultrasound, by karyotyping and by post‐abortem autopsy. 8, American Journal of Medical Genetics, Vol. The baby was diagnosed with a significant and severe brain abnormality called Alobar Holoprosencephaly. 1 This condition is invariably associated with a wide range of midfacial defects ranging from a single incisor to cyclopia. A normal face is present in 17% of cases. The autopsy ( Figure 3d) confirmed the diagnosis of alobar holoprosencephaly associated with cyclopia with two eye‐anlagen, proboscis, and a … 5, The Journal of Pediatrics, Vol. 7, No. Embryopathologic and ultrasound findings are reported in five cases of alobar holoprosencephaly that were diagnosed prenatally, two cases as early as 23 menstrual weeks. All of them confirmed posteriorly by MRI at 20 weeks. Semilobar holoprosencephaly is a subtype of holoprosencephaly characterised by incomplete forebrain division. 2 Alobar holoprosencephaly information for health professionals HP_AH_V1 June 2009 Aim The aim of this information sheet is to support staff involved in counselling pregnant women and their partners when a suspected or confirmed diagnosis of alobar holoprosencephaly (HPE) has been made, following an ultrasound scan. Children with a semi-lobar or lobar subtype can survive for approximately two years after the diagnosis of holoprosencephaly. 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. After birth, the patient was demonstrated to have a minute deletion of chromosome 21q22.3. That term is a fancy way of saying that the brain did not divide into the normal two hemispheres. Methods: A database of 1750 fetuses with congenital anomalies identified by ultrasound was prospectively collected from 1987 to 2000. Holoprosencephaly has been divided into three subcategories based on the structural malformation: alobar, semilobar, and lobar HPE. video demonstrating the fused ventricles in alobar holoprosencephaly at 12 weeks. 14, No. Specific sonographic findings included a large central cranial fluid collection (a monoventricular cavity lacking ventricular horns and midline structures), a fused thalamus at the floor of this cavity, and characteristic facial features (proboscis, single orbit, single nostril, or severe hypotelorism). Alobar holoprosencephaly characterised by median malformations of the face and brain due to incomplete cleavage and morphogenesis of the fore brain. 22, No. Ultrasound is a good modality for prenatal diagnosis of holoprosencephaly that is frequently associated with midline face deformity such as cleft lip and palate. [3–5] Demyer and Zeman suggested this resulted from a defect in the ventral induction and from the patterning of the rostral neural tube by the p… Holoprosencephaly (HPE) is the commonest congenital brain malformation and indicates absent or incomplete midline cleavage of the brain. The alobar form of holoprosencephaly, which is the most severe form, has the worst prognosis and most children do not survive beyond six months. On prenatal ultrasound, an intact falx and a fluid-filled cranium can be seen. The autopsy ( Figure 3d) confirmed the diagnosis of alobar holoprosencephaly associated with cyclopia with two eye‐anlagen, proboscis, and a … The main differential considerations for very large ventricles (> 20 mm) on prenatal ultrasound are hydranencephaly, alobar holoprosencephaly, and massive (maximal) hydrocephalus. 34, No. There are three types: alobar, semilobar and lobar. A series of 10 consecutive cases of alobar holoprosencephaly is described. 34, No. Alobar holoprosencephaly is a subtype of holoprosencephaly (HPE), and is the most severe of the classical three subtypes, with both semilobar and lobar holoprosencephaly having less severe clinical manifestations. [10, 11] 4, Journal of Clinical Ultrasound, Vol. The microcephaly was confirmed associated with hypertelorism and a frontal encephalocele. 4, Ultrasound in Medicine & Biology, Vol. 1 This condition is classified according to brain structures into lobar, semilobar, and alobar, the latter being the most severe form.
