If you know the vertex number, then you can do something like mri_volsynth --template $SUBJECTS_DIR/subject/surf/lh.thickness --pdf delta --delta-crsf vertexno 0 0 0 --o delta.mgz
mris_fwhm --smooth-only --fwhm 5 --i delta.mgz --subject subject --hemi lh --o delta.sm05.mgz mri_binarize --i delta.sm05.mgz --min .000000001 --o delta.sm05.bin.mgz tksurferfv subject lh inflated -fminmax .5 1 -ov delta.sm05.bin.mgz This is a fairly convoluted method that basically creates a surface overlay with a 1.0 in your vertex and 0 everywhere else (delta.mgz), then smooths that to distribute non-zero values around the vertex, then binarizes it.
