Recent advances in genetics and neuroimaging of children with holoprosencephaly (HPE) are reviewed from Stanford University School of Medicine, CA. Semilobar holoprosencephaly occurs due to mayhem of prosencephalic cleavage. In lobar holoprosencephaly, there is normal cortical division and two thalami, but abnormalities exist in the corpus callosum, septum pellucidum, or olfactory tract or bulbs. Lobar holoprosencephaly is the least severe of the classical subtypes of holoprosencephaly (HPE), characterized by the presence of the inter-hemispheric fissure along almost the entire midline, and with the thalami being completely or nearly completely separated 5. The aim of this study was to evaluate the contribution of MRI in patients with CNS anomaly detected by USG. A hundred and seventy files were revised and studied with malformitys. 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. ... A neonate with semilobar holoprosencephaly was studied with diffusion tensor imaging and fiber tracking. 4. Four major types of HPE are delineated by MRI findings: alobar, semilobar, lobar, and middle interhemispheric (MIH) variant, the lobar and MIH types being most prevalent. Ultrasonography (USG) is the primary method for antenatal fetal evaluation. However the face may even be almost normal in few cases of alobar holoprosencephaly as in our case. Radiographics. 1.
