“…In this study, MR performed better than US in 12 cases (24.5%) among the 49 pregnancies receiving both methods. This nding combined with our previous study [19,22] and the results reported in the literature [25] demonstrated that for foetuses with suspected intracranial complicated malformations or unclear US images, MR is highly recommended for further evaluation to determine some severe aetiologies. In one study [17], researchers reported that vermis length discrepancy or inferior vermian distance greater than or equal to 4 mm was associated with abnormal neurologic outcome.…”

“…Intracranial haemorrhage was also often encountered in the cerebellar anomaly group in the present study. Intracranial haemorrhage often appeared as a patchy low signal on the HASTE sequence, and occasionally, the corresponding high signal on T1WI indicates that the bleeding process is fresh and newly formed [19]. However, porencephaly, the secondary consequence of intracranial haemorrhage, was not found in the present studied samples.…”

“…Dandy-Walker malformation, TCS, intracranial haemorrhage, and posterior fossa cyst (Blake's pouch cyst or cisterna magna arachnoid cyst) were the most common pathological types based on their frequency of occurrence in this study. MRI is an adjunct to US in diagnosing intracramnial hemorrhages in utero which helps to assess postnatal development [19]. Fetuses with open spina bi da present frequently Dandy-Walker anomaly and descent of the cerebellum in the foramen magnum with a peculiar pro le aspect as described recently [20].…”

Purpose: To clarify the prenatal magnetic resonance (MR) imaging characteristics of foetal cerebellar dysplasia/hypoplasia and developmental malformations and evaluate their diagnostic value. Methods: We retrospectively reviewed MR images of foetuses with suspected intracranial anomalies on screening ultrasound (US) on picture archiving communication system (PACS) servers within a five-year period in our institution. The main abnormal findings and coexistent anomalies were recorded by two experienced radiologists with census reading. The MRI and US results were paired and compared in each case. Results: We recruited 121 cases (average gestational week, 24.5 ± 4.7 weeks) with prenatal MR imaging, including sixty-two cases with simple cerebellar dysplasia or hypoplasia, thirty-one cases with other anomalies and twenty-eight cases with normal MR imaging findings. Cerebellar anomalies included intracranial haemorrhage, arachnoid cysts, Blake’s pouch cysts, Dandy-Walker malformation, cerebellar tonsil hernia and vermis absence. Coexistent cerebral malformations included hydrocephalus, cerebral haemorrhage, holoprosencephaly, brainstem/gyri malformation, ventriculomegaly and agenesis of the corpus callosum. Other detected systemic malformations included tethered cord syndromes (9 cases), club foot (1 case), cardiac malformation (1 case) and lip-palate cleft (1 case). Among 49 cases with both prenatal MR and US, MR imaging confirmed the diagnosis and/or provided more abnormal findings than US in 12 cases. Two dead babies after birth were recorded in cerebellar malformation group. Conclusion: Prenatal MR imaging could better show cerebellar anomalies and coexistent systemic malformations. As a complementary tool of US, MR imaging could help prenatal counselling and treatment selection at term.

“…As a reliable complimentary tool to US, magnetic resonance imaging (MRI) can depict intracranial anatomic structures well and show multiple system anomalies in one scanning plane [6][7][8]. Unlike MRI characteristics detected in infants or adults, imaging characteristics of foetal ICH vary depending on when and where the haemorrhagic components occur [9]. Coexistent malformations also complicate an accurate diagnosis and evaluation of these abnormal ndings on prenatal MRI [10].…”

Purpose To clarify the prenatal magnetic resonance (MR) imaging characteristics of foetal intracranial haemorrhages (ICHs) in a large cohort and correlate them with birth outcomes. Methods We retrospectively reviewed MR images of foetuses with ICH on screening ultrasound (US) on picture archiving communication system (PACS) servers within a nearly five-year period from two medical tertiary centres. The indications, main abnormal findings and coexistent anomalies were recorded by two experienced radiologists with census readings. Results We recruited 81 cases (average gestational week, 28.0 ± 5.0 weeks) with prenatal MR imaging, including 71 singleton pregnancies and 10 monochromic twin pregnancies. Predominant coexistent anomalies were ventriculomegaly (35.8%), holoprosencephaly or porencephaly (13.6%) and enlarged posterior fossa/ or posterior fossa cyst (7%) in the lesion-based evaluation. The number of haemorrhagic lesions and the occurrence of the detected complications did not show a correlation with the size of the haematoma. The mass effect of ICH was more commonly observed in foetuses with a large for gestational age (GA) than in foetuses with a small for GA. Conclusion Prenatal MR imaging could better show ICH morphology and associated abnormal findings. As a complementary tool of US, MR imaging could help with prenatal counselling and treatment selection after birth.
