1 A, Axial T2-weighted MR image shows the classic MTS, including thickened, elongated, parallel, and horizontally orientated SCP (thick white arrows) and a deepened IF (thin white arrow). A, Axial T2-weighted MR image shows the classic MTS, including thickened, elongated, parallel, and horizontally orientated SCP (thick white arrows) and a deepened IF (thin white arrow). B, Midsagittal T2-weighted MR image demonstrates a severe vermian hypoplasia-dysplasia (thin black arrows), and distortion and enlargement of the fourth ventricle with rostral shifting of the fastigium (thick black arrows), enlargement of the PF, a deepened IF (white arrow), and a narrow pontomesencephalic isthmus.
