Correct answer: E — Parietal lobe optic radiation (superior fibres)
The best answer is “Parietal lobe optic radiation (superior fibres)”. Neuro-oncology management depends on anatomical compartment, histology, molecular classification, growth, neurological deficit and resectability, with specialist multidisciplinary planning. The alternatives “Meyer's loop in the temporal lobe”, “Optic chiasm, when the phenotype supports it”, “Optic nerve, within the relevant UK pathway”, “Calcarine cortex, after excluding important mimics” are clinically adjacent possibilities, but they do not match the defining chronology, localisation, physiology, investigation result or UK management sequence in this stem.
