Midsagittal 3D-CISS image of a 12-year-old boy with NF-1 reveals periaqueductal/tectal hamartomas (thin arrows), superior velum medullary synechia (thick arrow), and the stoma at the floor of the third ventricle (arrowheads) at 3-month follow-up after ETV.

A, Midsagittal TSE T2 image of a 9-year-old boy with NF-1 shows minimal T2 hyperintensity and slight enlargement in the tectum without causing hydrocephalus. B, Twenty months later, midsagittal 3D-CISS image demonstrates an inferior aqueductal web in addition to hamartomas in the tectum causing severe triventricular hydrocephalus.

A, Midsagittal 3D-CISS image of a 10-year-old boy with NF-1 demonstrates severe triventricular hydrocephalus. The cerebral aqueduct is wide open (black arrow). The tectum (white arrowheads) is thin and displaced posteriorly. However, the fourth ventricle inlet is obliterated due to hamartomas filling the ventricle (white arrows). B, Axial TSE T2 image obtained through the midbrain reveals extensive cerebellar hamartomas mostly in the cerebellar vermis.
