Figure 2.
Fetus at 20 weeks’ gestational age with echogenic material in the frontal horn on sonography and porencephaly on MRI. A, Coronal transabdominal sonogram showing echogenic material in 1 frontal horn with expansion of the horn (arrow). B, Coronal T2-weighted MRI showing expansion of the involved frontal horn and a low signal within the ventricle, representing hemorrhage (arrow). There is irregularity of the lateral wall of the ventricle (arrowhead). C, Coronal T2-weighted MRI showing high-signal intensity CSF extending outside the normal confines of the ventricle and into the parenchyma, consistent with porencephaly (arrowhead), which was not shown on the sonogram.
