“…However, it is impossible to differentiate between a lesion in the subdural space and a lesion in the venous sinuses. Detection of additional cloths in the pericerebral space is more suggestive of subdural hemorrhage; however, a combination of both can occur [1] .…”

“…Although fetal hemorrhage can occur spontaneously of unknown origin, fetal trauma, congenital infection, maternal coagulopathy (medicamentous), vascular-cardiac malformations, intrauterine hypoxia etc. are considered as predisposing factors [1][2][3][13][14][15] . In fetal trauma, sacral compression or acceleration-deceleration forces can result in subdural and -arachnoidal hemorrhages; however, direct trauma on the fetal head is very rare before the third trimester [16,17] .…”

Objective: To describe the magnetic resonance imaging findings of an antenatal intracranial venous thrombosis. Methods: Prenatal ultrasound (US) at 22 weeks’ gestational age (GA) in a 27-year-old patient (G2 P1) revealed a nonspecific avascular echogenic mass above the cerebellum evaluated with MRI at 23 weeks’ GA. Results: With MRI an enlarged occipital pericerebral space with a layered ovoid mass at the torcular herophili was demonstrated and MRI characteristics suggested a subacute cloth. In follow-up, an important enlargement of the mass was noticed on US examinations. After multidisciplinary consult and parental consent, a prostaglandin induction was performed at 25 weeks’ GA. The baby died immediately after birth. Pathology confirmed the diagnosis of a venous thrombosis at the torcular herophili with extension into the superior sagittal sinus. Conclusion: In our case, MRI findings were helpful in diagnosing an intracranial fetal venous thrombosis.

Twins have an increased risk for congenital malformations and disruptions, including defects in brain morphogenesis. We analyzed data on brain imaging, zygosity, sex, and fetal demise in 56 proband twins and 7 less affected co-twins with abnormal brain imaging and compared them to population-based data and to a literature series. We separated our series into malformations of cortical development (MCD, N = 39), cerebellar malformations without MCD (N = 13), and brain disruptions (N = 11). The MCD group included 37/39 (95%) with polymicrogyria (PMG), 8/39 (21%) with pia-ependymal clefts (schizencephaly), and 15/39 (38%) with periventricular nodular heterotopia (PNH) including 2 with PNH but not PMG. Cerebellar malformations were found in 19 individuals including 13 with a cerebellar malformation only and another 6 with cerebellar

We report the case of a fetus with a sonographic diagnosis of hyperechogenic cerebellum at 28 weeks' gestation, which was suspected to be of hemorrhagic origin on fetal ultrasound. As an adjunct to ultrasound, fetal MRI can confirm the hemorrhagic origin of hyperechogenic cerebellar lesions, particularly by showing a high signal on T1‐weighted images. No etiological factors for fetal hemorrhage were found other than maternal hypertension and aspirin use. Postnatal MRI confirmed the prenatal diagnosis of cerebellar hemorrhage without underlying vascular anomaly.
