Abstract: | PIK3CA‐related overgrowth spectrum, caused by mosaic mutations in the PIK3CA gene, is associated with regional or generalized asymmetric overgrowth of the body or a body part in addition to other clinical findings. Three‐dimensional ultrasonography (3‐D US) has the capability to display structural abnormalities in soft tissues or other organs, thereby facilitating identification of segmental overgrowth lesions. We present a case suspected of having a segmental overgrowth disorder based on 3‐D US, whose chromosomal microarray result was abnormal, but apparently was not the cause of the majority of the fetus's clinical features. |
