Sumario:PURPOSE: To report a case of congenital geniculate quadruple sectoranopia associated with occipital heterotopia. OBSERVATIONS: A 51-year-old healthy woman was incidentally found to have a left incongruous quadruple sectoranopia. Analysis of the macular ganglion cell complex (GCC) revealed homonymous hemianopic thinning of the inner layer of the retina. Brain magnetic resonance imaging (MRI) showed congenital occipital heterotopia, characterized by hypertrophy of the right parahippocampal gyrus, lingual gyrus, and isthmus of the cingulate gyrus, with shrinkage of the white matter. In addition, serial coronal images on a short tau inversion recovery (STIR) sequence demonstrated an atrophic right optic tract. CONCLUSION AND IMPORTANCE: Congenital geniculate quadruple sectoranopia is extremely rare and may be caused by congenital occipital heterotopia.
