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.

AIM To show imaging results from application of fourdimensional(4D) ultrasound lightening technique(HDlive^(TM)) in clinical obstetrics practice. METHODS Normal and abnormal fetuses at second and third trimester of pregnancy undergoing routine scan with 4D HDlive^(TM)(5DUS) in the rendering mode are described. Realistic features of fetal structures were provided by 5DUS in the rendering mode. Normal anatomy as well as pathology like cleft lip, hypoplastic face, micrognathia, low-set ears, corpus callosum, arthrogryposis, aortic arch, left congenital diaphragmatic hernia are highlighted in this study. Anatomical details of the fetuses were provided by 5DUS with higher quality imaging modality compared to those obtained using conventional 2D/3D ultrasound. RESULTS Realistic views of fetal anatomy details were displayed by means of 5DUS in the rendering mode, with high image quality obtained either in low-risk or in high-risk obstetrics population. Corpus callosum, esophagus, and aortic arch were obtained in normal fetuses. Cleft lip, cleft lip and palate, micrognathia, hypoplastic face, lowset ears, arthrogryposis, left congenital diaphragmatic hernia, exomphalos, and clitoris hypertrophy were clearly rendered by 5DUS *** The use of 5DUS in the rendering mode, when clinical available, was diagnostic in a variety of congenital anomalies, aided understanding of the parents-tobe and improved prenatal counseling and perinatal management.

Aicardi syndrome is a rare genetic disease characterized by a characteristic classical trio of neurological clinical abnormalities(spasms),agenesis of the corpus callosum and ophthalmological abnormalities(chorioretinal lacunae).The diagnosis can be suspected by prenatal ultrasound with color Doppler identifying the agenesis of the corpus ***,the diagnosis is confirmed in the neonate period by transfontanellar ultrasound and ophthalmological *** present a case of newborn with Aicardi syndrome,being the transfontanellar identified partial dysgenesis of the corpus callosum and a cyst in the inter-hemispheric *** examination showed bilateral chorioretinal lacunae.

Advent in three-dimensional(3D) imaging technology has seen 3D ultrasound establish itself as a useful adjunct complementary to traditional two-dimensional imaging of the female pelvis. This advantage largely arises from its ability to reconstruct the coronal plane of the uterus, which allows further delineation of many gynecological disorders. 3D imaging of the uterus is now the preferred imaging modality for assessing congenital uterine anomalies and intrauterine device localization. Newer indications include the diagnosis of adenomyosis. It can also add invaluable information to delineate other endometrial and myometrial pathology such as fibroids and endometrial polyps.
