Summary
Bilateral posterior cerebral artery infarction caused persistent memory loss and vision deficits in a 70-year-old man. Unlike typical cases, his neurological symptoms did not resolve after two months.
Area of Science:
- Neurology
- Neuroimaging
- Vascular Neurology
Background:
- Posterior cerebral artery (PCA) territory infarction can lead to diverse neurological deficits.
- Bilateral PCA infarctions are rare and can present with complex symptoms.
- The prognosis and symptom resolution in bilateral PCA infarction are not fully understood.
Observation:
- A 70-year-old male presented with acute short-term memory impairment.
- He also exhibited a left inferior homonymous quadrantanopia.
- These symptoms were attributed to simultaneous bilateral PCA territory infarction.
Findings:
- No specific etiological cause for the infarction was identified in this patient.
- In contrast to some reported cases of unilateral PCA infarction with transient symptoms, this patient's deficits were persistent.
- Neurological deficits remained evident at the 2-month follow-up assessment.
Implications:
- This case highlights the potential for persistent neurological deficits following bilateral PCA infarction, even without an identifiable cause.
- It underscores the importance of thorough neurovascular evaluation and long-term monitoring in patients with PCA territory strokes.
- Further research into the mechanisms underlying persistent deficits in bilateral PCA infarction may inform therapeutic strategies.

01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
