Figure 1: (a) T2w sagittal image shows flat anterior pons (orange arrow) with cap-like bump on dorsal pons (green arrow). Midbrain-pons junction appears short (red arrow). Pons immediately below the dorsal bundle is thin. (b) Sagittal DTI image shows elongated superior cerebellar peduncle in blue-pink color fibers (red arrow). (c and d) Axial DTI images show absence of ventral decussation fibers in pons (red arrow) with ectopic thick light blue transverse bundle on pons (yellow arrow). Pink color middle cerebral peduncles are hypoplastic (green arrow). Corticospinal tracts are hypoplastic (red arrow)
