Fig. 3From: Involvement of the visual pathway is not a risk factor of visual field deficits in patients with occipital arteriovenous malformations: an fMRI studyCase 42. A 10-year-old male without a history of hemorrhage. a Enhanced structural axial T1-weighted image showing a left occipital diffuse AVM with a maximum diameter of 57.1 mm (yellow line). b–d Based on enhanced structural axial T1-weighted image, fiber tracking showing theasymmetry of optic radiation (green), and visual cortex (blue). Both the AVM-OR and AVM-VC distances were zero. e–f Visual fields testing showing normal visual fieldsBack to article page
