    Objective: To recognize and describe the ultrasonographic findings of fetuses diagnosed with intracranial hemorrhage, confirmed by magnetic resonance imaging. Patients and methods: 411 MRI exams of fetuses with CNS changes detected on routine ultrasonography, and confirmed by a specialist in fetal medicine in our service, performed from 2004 to 2015, were retrospectively reviewed. Fetuses with intracranial hemorrhage confirmed by MRI were divided into 3 groups, according to their location: encephalic (group 1), extra-encephalic (group 2) and encephalic and extra-encephalic (group 3). Group 1 was subdivided into 4 types: subependymal (1A); Subependymal with extension to white matter or parenchyma thinning (1B); Subependymal to the cortex ie the entire parenchyma thickness (1C) and diffuse encephalic hemorrhage supra and infratentorial (1D). After this division such fetuses had their ultrasound reports reviewed. Results: MRI findings: 5.8% (24/411) presented intracranial hemorrhage; 75% (18/24) encephalic (group 1); 12.5% ??(3/24) extraencephalic (group 2); 12.5% ??(3/24) encephalic and extra-encephalic (group 3). Among the fetuses with brain hemorrhage (group 1), subependymal involvement (1A) was observed in 22% (4/18); Subependymal and adjacent white matter (1B) in 28% (5/18); Of all parenchymal thickness (1C) in 44% (8/18) and diffuse of the cerebral parenchyma and cerebellum (1D) in 5% (1/18). In group 2 all the fetuses presented arteriovenous malformation (AVM): 33.3% (1/3) AVM pial; 33.3% (1/3) dural MAV and 33.3% (1/3) Galene vein malformation (MFVG). In group 3, it was observed an AVM of the MFVG type, with major cerebral ischemia in 33.3% (1/3) and subdural and subarachnoid haemorrhage, associated with involvement of the cerebral parenchyma in 66.7% (2/3). Ultrasound findings: ventriculomegaly was the most prevalent finding (87.5%, 21/24), isolated in only 1 case and with a statistically significant association with peri or intraventricular changes (p = 0.028), with masses (p = 0.009) And with deviations of the midline structures (p = 0.013). Conclusion: ventriculomegaly is the main ultrasonographic alteration related to intracranial hemorrhages, especially when associated with other findings, detectable in routine ultrasonography, allowing diagnostic follow-up with dedicated laboratory and imaging exams
