ABSTRACT
Objective To assess the prenatal features of dural sinus malformation (DSM) by ultrasound. Methods The prenatal ultrasonography and MRI examination were applied in three fetuses who were suspected as brain abnormalities and transferred to Shenzhen Maternity and Child Healthcare Hospital for detailed antenatal ultrasound examination. Comparative analysis was performed on MRI, autopsy and prenatal ultrasonography. The prenatal characteristics were summarized. Results In the sonograms of all three cases, the torcular Herophili and superior sagittal sinus were dilated. No blood lfow was detected within or around lesions by color Doppler imaging. Posterior intracranial dual sinus thrombosis was detected in one case. MRI examinations were applied in two fetuses. The results of prenatal ultrasonography were consisted with those of MRI, MRI imaging showed dilated torcular Herophili and superior sagittal sinus with short T1 and short T2 signal. The thrombosis was presented as iso-hypointense with focal eccentric hyperintense. One case was undertook autopsy and the result was consisted with the prenatal sonographic findings. Conclusions The typical sonographic features of DSM is dilated torcular Herophili and superior sagittal sinus with no blood lfow in color Doppler imaging. DSM should be excluded when anechoic area was detected at the rear part of midline.
