“…In some cases the presence of microcephaly may be suspected based on additional sonographic findings like: small frontal lobe [23], sloping forehead [24], enlarged subarachnoid space [24,25] and/or abnormal power Doppler demonstration of the anterior and middle cerebral arteries [24]. …”

“…The differential diagnosis in these cases is difficult. The demonstration of an enlarged subarachnoid space, particularly in the frontal region, in a fetus with macrocephaly is suggestive of benign enlargement of the subarachnoid spaces and is usually associated with a good prognosis (when the head circumference is normal or low enlarged subarachnoid spaces may imply brain atrophy) [25]. …”

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 usually only made in families with a previously affected child or in many cases be mere chance. In this article we review the feasibility of prenatal diagnosis of disorders of brain proliferation: microcephaly, macrocephaly, hemimegalencephaly and neoplastic and non-neoplastic abnormal cell types. We discuss the differential diagnosis and offer a stepwise approach to the diagnosis of the more common disorders.

“…Subarachnoid space width in infants has been evaluated by ultrasonography in several studies (Libicher and Tröger 1992; Lam et al 2001; Frankel et al 1998), but there is only one study which investigated the normal values in fetuses (Malinger et al 2000). The authors measured sinocortical width (SCW) and craniocortical width (CCW) in coronal section using transvaginal ultrasound (Malinger et al 2000).…”

Objectives To determine the feasibility of evaluating the subarachnoid space by measuring two novel sonographic parameters in axial section using transabdominal ultrasound, in addition to the parameters previously defined in coronal section, and to construct a normal range for the subarachnoid space width in singleton healthy fetuses.MethodsHealthy pregnant women between 20 and 29 weeks were scanned using transabdominal ultrasound. Four variables were measured for the evaluation of subarachnoid space width; sinocortical width and anterior craniocortical width in coronal plane, and lateral and posterior craniocortical width in axial plane.ResultThe data of 154 patients were recorded. SCW could be measured in 87.6 % (135) of fetuses, while the same figure was 77.9 % (120), 96.1 % (151) and 98.1 % (148) for anterior, lateral and posterolateral CCW, respectively. The SCW and anterior CCW did not display a significant correlation with gestational age and head circumference. The mean of SCW was 1.55 ± 0.41 mm with a range of 0.85–3.87 mm. The mean anterior CCW was 1.63 ± 0.39 mm with a range of 0.85–2.82 mm. A linear regression line was plotted between gestational age and lateral CCW (r = 0.707; p < 0.0001) and posterolateral CCW (r = 0.437; p < 0.0001), and nomograms for these parameters are constructed.ConclusionThis study presents a novel approach for the in utero evaluation of the subarachnoid space with two measurements in axial plane using transabdominal ultrasound. The nomograms will be helpful when there is a suspicion of subarachnoid space dilatation during routine cranial scan.

“…Por ello determinadas estructuras consideradas en el límite superior de la normalidad, podrían ser incluídas dentro de la normalidad gracias a tablas ajustadas por sexo y por edad gestacional. Nuestro estudio determina es no lineal, de forma estadísticamente significativa para el craneocortical, de la misma manera que lo apoya el trabajo de Malinger realizado en 2000, pero incluyendo únicamente 80 fetos, es decir, con una muestra menor a la de nuestro trabajo (68). En conclusión, nuestro estudio describe una relación lineal entre parámetros neurosonográficos y edad gestacional.…”
