Visual field testing, structural MRI, and tractography findings in the presented case with right temporal lobe polymicrogyria. HVF test revealed a left homonymous upper quadrant defect (A). OD represents the right eye, and OS represents the left eye. T1-weighted MRI images displayed a reduced volume and polymicrogyria in the right temporal lobe (indicated by arrow) in both coronal (B) and sagittal (C) views. Tractography demonstrated decreased volume (indicated by arrow) and fractional anisotropy in the right section (red) of Meyer’s loop, contrasted with the left section (yellow) (D). HVF, Humphrey visual field; MRI, magnetic resonance imaging; OD, oculus dexter; OS, oculus sinister.
