Acquired lesions of fetal CNS are those fetal CNS lesions caused by disruptive process, not for abnormal embryogenesis. They represent the third indication of fetal cerebral MRI after ventriculomegaly and CNS malformations. The aim of this exhibit is: To show the spectrum of fetal acquired lesions, to describe the most frequents found imaging findings and to discuss the role of prenatal MRI in the diagnosis and follow-up of these entities.  

For didactic purposes, we classify acquired lesions of fetal CNS in: 1. Intracranial hemorrhage. In the fetal intracranial hemorrhage, predisposing factors are maternal trauma, fetal coagulation disorders (alloimmune thrombocytopenia) and maternal anticoagulant therapy. In this educational poster representative cases of intraventricular hemorrhage, infratentorial hemorrhage and subdural hematoma will be presented. 2. Hypoxic-ischemic injury. We will present representative cases of porencephalic cysts, schizencephaly, microcephaly, cerebral atrophy and hydranencephaly. We also will discuss cases of feto-fetal transfusion. 3. Vascular malformations. Particularly, vein Galen malformation. 4. Infections. Mainly cytomegalovirus, causing white matter lesions, microcephaly, polymicrogyria, calcifications and cerebellar hypoplasia. 5. Tumors / cysts
