Thickened superior fronto-occipital fasciculus. T1WI, direction-encoded color maps with associated fiber orientation distribution glyph profiles, and tractography reconstructions in 3 patients with thickened SFOFs (A–C) and in the age-matched healthy control template for comparison (D). Patient A has bilateral peri-Sylvian PMG plus a left schizencephaly and a thickened right SFOF (arrowheads). The left SFOF cannot be recognized. Patients B and C demonstrate pachygyria and subcortical band heterotopia and bilateral thickened SFOF (arrowheads). On FOD glyphs maps, 1 indicates the SFOF (green, predominately anterior-posterior oriented fibers), and 2, the corpus callosum (red, predominately left-right oriented fibers).
