BACKGROUND & OBJECTIVES Prenatal diagnosis of malformations is an important method of prevention and control of congenital anomalies with poor prognosis. Central nervous system (CNS) malformations amongst these are the most common. The information about the prevalence and spectrum of prenatally detected malformations is crucial for genetic counselling and policymaking for population-based preve...

BACKGROUND AND PURPOSE Although sonography is the primary imaging technique for evaluating the developing fetus, significant limitations exist in the sonographic prenatal diagnosis of many brain disorders. Fast MR imaging is increasingly being used to determine the underlying cause of nonspecific fetal CNS abnormalities detected sonographically and to confirm or provide further support for such...

to determine easily identifiable congenital anomalies (ca) prevalence and risk factors in the first 24 hours of life in a cross-sectional study we assessed 2291 live born neonates at four teaching hospitals from september 1999 until march 2000 in the south of tehran. data were collected by a structured form which contained neonatal characters including sex, gestational age, birth weight, histor...

Neurosurgeons deal with the most vulnerable human organ, the central and peripheral nervous system (CNS and PNS): the brain and its efferent and afferent neural structures (spinal cord), and peripheral nerves. Also, the CNS blood vessel system as well as the CNS surrounding structures, like the membranes covering the CNS tissue and the bony elements enveloping the CNS (skull and spinal column),...

BACKGROUND Oral-facial-digital type 1 syndrome (OFD1; OMIM 311200) belongs to the expanding group of disorders ascribed to ciliary dysfunction. With the aim of contributing to the understanding of the role of primary cilia in the central nervous system (CNS), we performed a thorough characterization of CNS involvement observed in this disorder. METHODS A cohort of 117 molecularly diagnosed OF...

Central nervous system(CNS) malformations are one of the commonest malformations that frequently encountered in pregnancy. It can vary from subtle to very severe defects. Most of them can be diagnosed with prenatal ultrasound. Objective: The purpose of our study was to describe the incidence of various CNS malformations and their imaging findings on antenatal ultrasound. Materials and Methods: ...

A considerable number of central nervous system pathologies remain undiagnosed during the first two trimesters of pregnancy. This group of disorders includes anomalies of brain proliferation, migration and cortical organization. Due to the fact that a detailed ultrasound examination of the fetal brain is usually not performed during the third trimester the diagnosis of these disorders is usuall...

Background: Using contemporary ultrasound equipment, it is possible to diagnose CNS defects in prenatal life. Many can be detected by the first and early second trimesters. 4D ultrasonography has a high sensitivity for detecting abnormalities used detect some foetal disorders.
