Unlike conventional color Doppler imaging; color Doppler energy (or power Doppler) displays the intensity of the returning Doppler signal, is less dependent on the orientation of the blood vessel, and is therefore better able to detect low blood velocities. For these reasons it could be useful in some investigations which are difficult to perform, such as transvaginal evaluation of fetal brain vessels. We report a case of a fetal intracranial hyperechoic lesion detected at 26 weeks by transabdominal sonography in a severely growth-retarded fetus. There was absence of diastolic flow in the umbilical artery and low impedance to diastolic flow in the middle cerebral arteries. The fetus was further investigated by transvaginal sonography for the evaluation of the nature and localization of the lesion and an intraventricular hemorrhage in the right brain parenchyma with disorganized supratentorial brain structure was observed. As color Doppler energy imaging is more sensitive to slow flow, it was more reliable than conventional Doppler imaging in confirming the absence of flow within and around the hyperechoic lesion in contrast to the normal vascularity of the contralateral ventricular system. After informed parental counselling, the mother, for psychological reasons, asked to be delivered by Cesarean section. The fetus died 24 h after birth. The autopsy corroborated the ultrasonographic diagnosis. This case report confirms the accuracy of transvaginal ultrasonography in the diagnosis of intracranial hemorrhage and suggests a specific role for color Doppler energy imaging. |
