The tumors most frequently found were those of the choroid plexus and teratomas. Out of those 18 cases, 11 patients presented with fetal hydrocephalus, and 5 of them, who were less than 34 weeks old (gestational age), underwent repeated cephalocenteses while awaiting better conditions for delivery. Two fetuses died while in utero before any intervention had taken place and 16 underwent craniotomy after birth. Twelve of those patients are still alive, 9 of whom are considered normal. The 3 others are slightly or moderately retarded.

Congenital central nervous system tumors diagnosed during pregnancy are rare, and often have a poor prognosis. The most frequent type is the teratoma. Use of ultrasound and magnetic resonance image allows the suspicion of brain tumors during pregnancy. However, the definitive diagnosis is only confirmed after birth by histology. The purpose of this mini-review article is to describe the general clinical aspects of intracranial tumors and describe the main fetal brain tumors.

Antenatal surgical repair of MMC reduced the need for postnatal shunt placements. Despite preterm delivery, the cognitive development of most children at 3.5 years was normal. Antenatal surgery seemed to improve lower limb motor function in these cases.

Objective To compare neuromotor development between patients who did and those who did not undergo intrauterine myelomeningocele repair. Methods Children with myelomeningocele aged between 3.5 and 6 years who did undergo intrauterine repair (Group A, n=6) or not (Group B; n=7) were assessed for neuromotor development at both anatomical and functional levels, need for orthoses, and cognitive function. Results Intrauterine myelomeningocele repair significantly improved motor function. The functional level was higher than the anatomical level by 2 or more spinal segments in all children in Group A and 2 children in Group B, with a significant statistical difference between groups (p<0.05). Five children in Group A and one in Group B were community ambulators. Conclusion Despite the small sample, it was observed that an improvement of motor function and decreased need for postnatal shunting in the 6 children who had undergone intrauterine myelomeningocele repair.

In Form von Rhomben und Quadraten liegt ein cyclisches Aminozucker‐Oligosaccharid mit vier Wiederholungseinheiten im Festkörper vor (siehe Bild). Kristalle mit einem bemerkenswert hohen Wassergehalt (ca. 34 %) wurden nach der Hanging‐Drop‐Methode aus einer Wasser/Polyethylenglycol‐Lösung gezüchtet.
