Summary

This summary is machine-generated.

Diffusion-weighted MRI (DW-MRI) can detect acute infarction even with very brief neurological symptoms. Early imaging aids diagnosis when clinical judgment is insufficient for transient ischemic attack.

Keywords:

MRI TIA Transient ischemic attack stroke transient symptoms with infarction

Area of Science:

Neurology
Radiology
Cardiology

Background:

Diffusion-weighted magnetic resonance imaging (DW-MRI) detects acute infarction in one-third of patients with suspected transient ischemic attack (TIA).
Infarct identification on DW-MRI increases with symptom duration.
Short events, even 10 minutes, have been linked to DW-MRI lesions.

Observation:

A case study of a healthy man with a 10-second neurological dysfunction episode.
The patient presented with atypical symptoms and no traditional risk factors for cerebrovascular disease.
The presentation made the diagnosis challenging.

Findings:

The patient exhibited DW-MRI lesions originating from a cardioembolic source.
Despite the brief and atypical symptoms, DW-MRI identified acute infarction.
The diagnosis was initially difficult due to the lack of typical risk factors and symptom duration.

Implications:

Early DW-MRI may be crucial for diagnosing infarction in patients with fleeting neurological symptoms.
DW-MRI can provide diagnostic value beyond clinical assessment in TIA cases.
This case highlights the utility of advanced imaging in identifying subtle or atypical cerebrovascular events.
