Objective: To evaluate the possible additional benefits of the Fetal MRI on Fetal Mild Cerebral Ventriculomegaly diagnosed with Fetal USG.
Methods: 48 Pregnancies with Fetal Cerebral Mild Ventriculomegaly with the atrial width range 10-15 milimeters were evaluated retrospectively. 48 Fetal US, 48 fetal MRI and 20 postnatal evaluation findings were compared.
Results: According to the Fetal US findings, amongst 48 Mild VMs, 26 were isolated and 22 were not. At 36 cases, ventricular width was between 10-12 mm and at 12 cases between 12,1-15 mm. At 26 out of 48 cases (54,1%), Fetal US and MRI were compatible but at 22 out of 48 cases ( 45,8 %), they were not. In the isolated VM group, at 17 out of 26 cases, Fetal MRI Confirmed Isolated VM, while at 9 cases MRI showed additional or different findings. At 8 out of 9, MRI showed cortical malformations and one case showed Corpus Callosum Dysgenesis additionally. In the non-isolated VM group, which was composed of abnormalities of posterior fossa ,cysts, haemorrhage, calvarial bone abnormalities, at 8 out of 22 cases, Fetal MRI was compatible with Fetal US and at 14 out of 22 cases, MRI showed additional or different findings. Fetal MRI showed additional/different findings than fetal US in 34.6% of cases with isolated VM and 63.6% of the non-isolated VM cases. 20 cases’ postnatal confirmations were made. Amongst 12 Fetal US/MRI compatible cases which have been evaluated postnatally; isolated group’s, non-isolated group’s and total postnatal confirmation ratios were 57, 100 and 75 percent, respectively (4/7, 5/5 and 12/12). In the Fetal US/MRI non-compatible cases, 8 postnatal confirmations were made. Fetal US and MRI findings had posnatal confirmation ratios as 22 and 25 percent respectively (3/8 and 2/8).
Conclusion: Fetal MRI showed additional/different findings than fetal US in 34.6% of cases with isolated VM and 63.6% of the non-isolated VM cases. In fetal cerebral mild ventriculomegaly cases, application of Fetal MRI has some additional benefits.
