An MRI of the fetus, at 34 weeks pregnancy, demonstrated semilobar holoprosencephaly. Within the second trimenon, the cephalic anomalies became evident when investigating the diameter of the fetal head (second trimenon: 71% below the fifth percentile; third trimenon: 92% below the fifth percentile).

Coronal view of the face of a fetus with holoprosencephaly demonstrates a decreased interorbital distance between the calipers (+), which measured 37 mm compared with a normal of 52 mm for a fetus of this gestational age (32 weeks). Griffiths PD, Jarvis D. In Utero MR Imaging of Fetal Holoprosencephaly: A Structured Approach to Diagnosis and Classification. Objective: To investigate the prenatal appearance of the holoprosencephaly spectrum. Holoprosencephaly (HPE) is a severe brain malformation characterized by abnormal cleavage of the prosencephalon in the 5th gestational week. Introduction These findings were suggestive of holoprosencephaly that was … , Tsui, L.C. In the current fetus, fusion of the frontal lobes, pathognomonic finding for holoposencephaly, was well demonstrated by intrauterine MRI. 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). Chatzipapas, I.K. Bookmarks (0) Brain. detected on fetal MRI. 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. e aetiology of holoprosencephaly is unknown.

Prenat Diagn 1998; 18: 477-480, Turner CD, Silva S, Jeanty It is important to examine the fetal face and skull during prenatal ultrasound examinations because abnormalities of these structures may indicate the presence of other, more subtle anomalies, syndromes, chromosomal abnormalities, or even rarer conditions, such as infections or metabolic disorders. LOBAR HOLOROSENCEPHALY 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.

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. , Fong, K.W. By continuing to browse Detailed ultrasound examination, including neurosonography. Management: Fetal karyotype is mandatory when holoprosencephaly is discovered by ultrasound; termination of pregnancy should be offered to parents of previable fetuses. Nevertheless, when the sonographic diagnosis is uncertain in cases shuch as maternal obesity, fetal size and position, the MR imaging can be helpful. Fetal Facial Abnormalities. Embryopathologic and ultrasound findings are reported in five cases of alobar holoprosencephaly that were diagnosed prenatally, two cases as early as 23 menstrual weeks. anterior cerebral artery is pushed externally alongside the frontal bone by the features of alobar holoprosencephaly. Indeed, 2 cases of holoprosencephaly in our series were detected in women originally requesting nuchal translucency screening.
