FIG 1. 11-year-old boy with holoprosencephaly. Coronal T1-weighted image (420/15/2) shows bilateral vertically oriented HFs (arrows).FIG 2. One-year-old infant with congenital Fukuyama muscular dystrophy. On coronal FLAIR image (10002/162/1, TI = 2200), neither HF shows inversion (arrows), their configurations are straight and vertical. Both temporal lobes have a smooth cortical surface (lissencephaly) with abnormal low-intensity white matter. Both frontal lobes have shallow sulci
