AB Retro-chiasmal lesions almost always give rise to homonymous field defects with only one exception. The nasal visual field extends to 60% of the horizon, whereas the temporal field extends to a further 30°–40° beyond that; this part of the visual field is represented on the contralateral anterior parieto-occipital sulcus. A lesion in this area will give rise to monocular visual field defect affecting the contralateral eye. This is called the temporal crescent or the half moon syndrome. In this case report, a woman presented with seizures secondary to haemorrhagic infarction of the anterior part of the parieto-occipital sulcus. She later presented with right-sided visual disturbance; her examination confirmed temporal crescent syndrome. I explain the pathophysiology of this rare neurological syndrome in this report.
