Intracranial translucency as a sonographic marker of open spina bifida at first trimester
Spina bifida is the one of the most common severe congenital abnormality of the central nervous system. Scalloping of the frontal bones called “the lemon sign” and caudal displacement of the cerebellum called “the banana sign” are known as cranial signs of open spina bifida on ultrasonography at the second trimester. Although these signs are useful methods in diagnosing of open spina bifida in ...
متن کاملFrom nuchal translucency to intracranial translucency: towards the early detection of spina bifida.
It is now clear that the vast majority of major fetal abnormalities can be diagnosed prenatally by ultrasound, that most of these abnormalities can be detected in the first trimester of pregnancy and that women want firsttrimester rather than later diagnosis. It is also clear that effective diagnosis of fetal abnormalities often necessitates the identification of easily recognizable markers whi...
متن کاملNeuroimaging parameters in early open spina bifida detection. Further benefit in first trimester screening?
OBJECTIVE Morphological investigation of the central nervous system (CNS) in fetuses with positive markers for open spina bifida (OSB) detection, visualized by ultrasound during the first trimester of pregnancy. MATERIALS AND METHODS Data from fetuses that underwent routine first trimester ultrasound scan in our center during September 2007-March 2011 and presented abnormal aspects of the fou...
متن کاملFirst-trimester screening for Dandy-Walker syndrome using intracranial translucency
Methods During a 3-year period from 2012 and 2015, consecutive women undergoing first-trimester screening for aneuploidy were routine examined for the presence of the IT in the sagittal plane of the fetal head by one FMF-accredited MFM specialist. The anterior-posterior diameter was measured and normative data were generated. Fetuses with increased IT were further studied with serial scans and ...
متن کاملAssessment of intracranial translucency (IT) in the detection of spina bifida at the 11-13-week scan.
OBJECTIVE Prenatal diagnosis of open spina bifida is carried out by ultrasound examination in the second trimester of pregnancy. The diagnosis is suspected by the presence of a 'lemon-shaped' head and a 'banana-shaped' cerebellum, thought to be consequences of caudal displacement of the hindbrain. The aim of the study was to determine whether in fetuses with spina bifida this displacement of th...
