EP03.03: Fetal neurosonography: experience and correlation with magnetic resonance images (MRI) in T2 weighted images (WI) at Hospital Italiano of Buenos Aires

Abstract

The aim is to describe our experience in fetal neurosonography, correlating them with the RMI T2WI and with the early evolution of the newborns. Retrospective evaluation of a series of cases evaluated with neurosonography between September 2014 and March 2017. In a total of 54 patients 61 evaluations were performed. The neurosonography was indicated: in 87% (47/54) of the cases due to CNS anomalies in routine obstetric ultrasound, in 3.7% (2/54) had previous child with CNS malformation, 3.7% (2/54) was indicated by the death of a twin monochorial pregnancy, 1.85% (1/54) had IUGR and 1.85% (1/54) for cardiac tumours. The mean gestational age (GA) at neurosonography was 29.4 weeks (range 21-37 weeks). The findings were: 15 normal ultrasound,10 corpus callosum alterations, 9 ventriculomegaly; 8 megacisterna Magna; 7 Blake's pouch cyst; 1 brain tumour; 1 Arachnoid cyst; 1 intracranial hemorrhage; 3 ventricular asymmetry; 1 posterior fossa hemorrhage; 4 holoprosencephaly; 1 microcephaly. MRI was performed in 57.4% (31/54) of the patients. In 96% (30/31) the findings visualised in T2WI were correlated with those of neurosonography. An evolutionary control was performed in 70.3% (38/54) of the newborns, of whom the 92.1 (35/38) presented evolution as expected for age, and 7.89% (3/38) neonatal died.
