Extended Pseudo-Subarachnoid Hemorrhage Post-Percutaneous Coronary Intervention

Area of Science:

• Neurology
• Radiology
• Cardiology

Background:

• Pseudo-subarachnoid hemorrhage (PSAH) is a rare condition.
• It can be mistaken for subarachnoid hemorrhage, leading to potential treatment errors.
• Understanding its causes is vital for accurate diagnosis.

Purpose of the Study:

• To report a unique case of extended PSAH.
• To highlight the association between PSAH and periprocedural events.
• To emphasize the importance of distinguishing PSAH from true subarachnoid hemorrhage.

Main Methods:

• Case report presentation.
• Review of neuroimaging findings.
• Correlation with periprocedural events.

Main Results:

• An extended PSAH was observed.
• The PSAH was related to contrast intracerebral diffusion.
• This occurred secondary to blood-brain barrier breakdown following percutaneous coronary intervention.
• The patient experienced a right corticofrontal ischemic stroke.

Conclusions:

• PSAH is a complex phenomenon requiring careful differentiation from subarachnoid hemorrhage.
• Prompt and accurate diagnosis is essential to guide appropriate patient management and avoid adverse outcomes.
