A Unique Case of Internuclear Ophthalmoplegia and Artery of Percheron Infarct.
Cureus
November 2024
Neurology, Dalhousie University, Halifax, CAN.
This case report discusses a unique presentation of an artery of Percheron (AOP) infarct resulting in rapidly resolving internuclear ophthalmoplegia (INO) without classical signs. This is the case of a 70-year-old male patient who presented to a community Emergency Department following acute code stroke activation. Physical exam and imaging studies including non-contrast CT, CT angiography, CT perfusion, and MRI were performed.

Rationale: Bilateral thalamic infarction is a rare type of posterior circulation stroke, and it often presents with a reduced level of consciousness in the elderly. Arteriosclerosis is the primary etiology of bilateral thalamic infarction, including conditions such as native vessel stenosis or arterial-to-arterial embolism. Cardiogenic or paradoxical embolism can also lead to thrombosis of the perforator branches innervating the thalamus, and these emboli tend to disintegrate and lead to multiple lesions, even in elderly patients.

Article Synopsis
- Othello syndrome is a type of psychosis where individuals wrongly believe their partner is cheating, often tied to psychiatric or neurological issues, including strokes.
- A case study details a 50-year-old woman with no prior psychiatric history who developed these delusions after a bi-thalamic stroke, resulting in severe aggressive behavior.
- The condition underscores the link between strokes and psychiatric symptoms, particularly in the right hemisphere, which can disrupt emotional regulation and lead to dangerous misunderstandings of a partner’s behavior.
Artery of Percheron Infarction with Bilateral Thalamic Lesions in a 14-Year-Old Girl: A Case Report.
J Nippon Med Sch
November 2024
Department of Pediatrics, Nippon Medical School Chiba Hokusoh Hospital.
The artery of Percheron (AOP), a common anatomic vascular variation of the P1 segment of the posterior cerebral artery, provides arterial blood supply to the paramedian thalami and rostral midbrain. Occlusion of the AOP can lead to infarction of the bilateral paramedian thalamus, with or without midbrain involvement, but is rare in children. Here, we describe a case involving a 14-year-old girl with sudden onset of disturbance of consciousness, hypersomnia, and global aphasia.

Department of Neurology, Jose R. Reyes Memorial Medical Center, Manila, PHL.
Occlusion of the artery of Percheron (AOP) is a rare yet potentially disabling form of ischemic stroke resulting in infarction of the bilateral paramedian thalami and mesencephalon with variable and often atypical presentation. Given the various patterns of thalamic blood supply, recognizing the presence of AOP infarction is crucial for the diagnosis and management of ischemic strokes involving these regions. Here, we report a case of acute hemorrhagic infarction involving the bilateral thalami and the rostral mesencephalon caused by a cardioembolic occlusion of the AOP.
