Olfactory axons project from nasal epithelium to the primitive telencephalon before olfactory bulbs form. Olfactory bulb neurons do not differentiate in situ but arrive via the rostral migratory stream. Synaptic glomeruli and concentric laminar architecture are unlike other cortices. Fetal olfactory maturation of neuronal differentiation, synaptogenesis, and myelination remains incomplete at term and have a protracted course of postnatal development. The olfactory ventricular recess involutes postnatally but dilates in congenital hydrocephalus...

Pial arteriovenous (AV) fistulae have rarely been diagnosed in utero. They are characterized by one or more pial arteries flowing directly into a cortical vein without any shunt or interposed capillary bed. In the fetus and the newborn up to 2 years of age, the most common clinical manifestation is heart failure resulting from fistula overload. Later on, hydrocephalus, focal neurologic deficits, headaches, seizures, and cerebral hemorrhage are the most common manifestations. We present a case of nongalenic pial AV fistula diagnosed in the 25th week of pregnancy, which resulted in intrauterine fetal death due to congestive heart failure...

This report describes a case of congenital toxoplasmosis in a newborn in Southern Italy. A pregnant mother had been admitted at the 20th week of her pregnancy on account of pharyngodynia and laterocervical lymphadenopathy. Although serological testing of the mother's serum documented a seroconversion with positive IgG and IgM anti-Toxoplasma antibodies during II trimester, the woman refused to perform prenatal diagnosis for congenital toxoplasmosis. Fetal ultrasound scan already showed mild asymmetrical triventricular hydrocephaly and cerebral calcifications...

Fetal-onset hydrocephalus is not only a disorder of cerebrospinal fluid (CSF) dynamics, but also a brain disorder. How can we explain the inborn and, so far, irreparable neurological impairment in children born with hydrocephalus? We hypothesize that a cell junction pathology of neural stem cells (NSC) leads to two inseparable phenomena: hydrocephalus and abnormal neurogenesis. All neurons, glial cells, and ependymal cells of the mammalian central nervous system originate from the NSC forming the ventricular zone (VZ) and the neural progenitor cells (NPC) forming the subventricular zone...

We report two Japanese patients with Schinzel-Giedion syndrome. When polyhydramnios is observed, additional fetal findings such as overlapping fingers, hydrocephalus, hydronephrosis, and very characteristic facial appearance comprising high, prominent forehead, hypertelorism, and depressed nasal root may suggest Schinzel-Giedion syndrome.

OBJECTIVE: While vein of Galen aneurysmal malformations (VGAM) can be diagnosed in the fetus, the challenge is predicting the occurrence of its two major complications: cardiopulmonary failure and encephalomalacia. This study attempts to determine which fetal brain MRI features might be used to predict the development of these complications at birth. METHODS: The cohort was extracted from a prospectively-assembled database of VGAM cases managed at a single referral centre from 2000 to 2014...

INTRODUCTION: Sacrococcygeal teratoma (SCT) is a rare tumor in the general population, arising from multipotent stem cells. Whereas most of the cases diagnosed postnatally have good prognosis, the rate of mortality and morbidities associated with prenatally diagnosed SCT remain high, with a reported mortality rate of 30% to 50%. The outcome of fetal SCT can be unpredictable, with some cases with slow growth during fetal life, whereas others grow rapidly, causing multiple complications; also, some of these tumor will develop triggering fetal (preterm delivery, high-output cardiac failure, hydrops fetalis, intrauterine death) or maternal complications (distocia, placentomegaly, maternal mirror syndrome-preeclampsia)...

REVIEW
Harvey B Sarnat, Laura Flores-Sarnat
After sagittal division of the prosencephalon at 4.5 weeks of gestation, the early fetal cerebral hemisphere bends or rotates posteroventrally from seven weeks of gestation. The posterior pole of the telencephalon thus becomes not the occipital but the temporal lobe as the telencephalic flexure forms the operculum and finally the lateral cerebral or Sylvian fissure. The ventral part is infolded to become the insula. The frontal and temporal lips of the Sylvian fissure, as well as the insula, all derive from the ventral margin of the primitive telencephalon, hence may be influenced by genetic mutations with a ventrodorsal gradient of expression...

INTRODUCTION: Intraventricular hemorrhage (IVH) is mostly documented in premature infants, and the younger the gestational age, the more often it occurs. IVH is very rarely reported in full-term neonates. CASE REPORT: Retrospective analysis was performed in 35939 full-term neonates, who were born in the Clinical Hospital of Gynecology and Obstetrics at the University of Medical Sciences in Poznań. Clinical data were retrieved from their medical records. We report a case series of 2 term newborns, who developed severe IVH grade 3 and 4 with no evidence of asphyxia, neuroinfection, TORCH infections, coagulation disorders and trombocytopenia, metabolic disorders, arteriovenous malformations, and selected genetic abnormalities (factor V Leiden 1601G > A polymorphism and MTHFR 677C > T; 1298A > C polymorphisms)...
