Abstract
A 31‐year‐old pregnant woman was referred for isolated mild ventriculomegaly and failure to visualize the left lateral ventricle's anterior horn on second trimester sonography (US). Three‐dimensional US suspected a frontal lesion deviating the midline. MRI revealed a mass compressing the ventricle. Follow‐up MRI described a “brain‐in‐brain” malformation: infolded microgyric cortex and white matter in frontal lobe extending to frontal horn and midline, irrorated by hypertophic Heubner artery. Conservative approach was chosen. Neurodevelopment at 1 year is normal. © 2009 Wiley Periodicals, Inc. J Clin Ultrasound, 2009
