It is possible. Try running defect-seg to see where the defects are. Run it

Hi freesurfer experts,

I have some cases where sulci near the occipital pole are reflected in the 
wm.mgz, but are filled in the white surface.
Attached is a capture showing the sulcus near the image center, where the 
crosshairs are located.

Might the topology fixer have filled in this sulcus, to reduce topological 
errors?
This was generated using recon-all -all, freesurfer 6.0, ubuntu 18.04.3.

Thanks,

Donna
