抜粋

Dural sinus malformation (DSM) is a rare congenital malformation characterized by a dilated dural sinus pouch.We present a case of prenatally diagnosed DSM and propose a parameter to predict poor fetal outcome. Detailed ultrasonography at 26 weeks of our patient showed an intracranial cyst in the left posterior fossa. Color Doppler study indicated an arteriovenous shunt within the cyst with increased blood flow velocity. Based on these findings, fetal DSM with arteriovenous shunt was diagnosed. Because of fetal hydrops with high-output cardiac failure and maternal pregnancy-induced hypertension, labor was induced at 32 weeks and resulted in stillbirth. In conclusion, based on the present case, we can deduce that color Doppler study is useful for prenatal diagnosis of DSM with arteriovenous shunt and that a high-flow velocity to the cystic lesion is a possible predictor of hydropic change in such fetuses.
