SUMMARY
The PCA supplies the upper brainstem, posterior-inferior surface of the temporal lobe & visual cortex.
SYMPTOMS
1. Contralateral homonymous hemianopia: with medial occipital lesions
2. Anton syndrome: when bilateral PCAs involved, may have denial of cortical blindness
3. Prosopagnosia: can't read faces
4. Palinopsia: abnormal recurring visual imagery
5. Transcortical sensory aphasia: can't understand written or spoken language but can repeat
6. CN III & IV palsies: the PCA supplies these cranial nerves via interpeduncular branches
7. Weber syndrome: occulomotor palsy & contralateral hemiplegia
