This is a major cause of basilar artery tip syndrome, potentially leading to multiple brain infarctions in regions such as the thalamus, midbrain, cerebellum, occipital lobe, and temporal lobe.
This can lead to infarctions in both occipital lobes at different times, presenting as cortical blindness and various visual agnosias, a condition known as Anton's syndrome.
This is a reversible vasogenic brain edema caused by specific clinical conditions, often presenting as extensive white matter abnormalities in the posterior hemispheres, particularly affecting the parieto-occipital regions bilaterally.
Caused by transient dysregulation of cerebral vascular contraction due to intracranial sympathetic nerve dysfunction, RCVS presents with thunderclap headaches, with or without focal neurological deficits or seizures.
This is a chronic occlusive cerebrovascular disease that may lead to ischemic strokes in the anterior circulation supply areas. Posterior circulation infarction usually occurs in the later stages of the disease, making cases where posterior circulation infarction is the initial symptom and leads to cortical blindness clinically rare.
These causes can lead to left occipital lobe infarction, resulting in various visual and neurological impairments. Timely diagnosis and treatment are crucial for improving patient outcomes.
