Pseudoradial Nerve Palsy Caused by Acute Ischemic Stroke

Area of Science:

• Neurology
• Neuroscience
• Stroke Research

Background:

• Pseudoperipheral palsy describes isolated limb weakness from stroke.
• Isolated hand nerve palsy is an uncommon stroke presentation.
• Stroke can mimic peripheral nerve lesions, leading to misdiagnosis.

Purpose of the Study:

• To highlight the importance of considering cerebral infarction in cases of isolated peripheral nerve palsy.
• To emphasize the diagnostic value of thorough clinical evaluation in differentiating stroke from peripheral nerve injury.

Main Methods:

• Case presentation of a patient with radial nerve palsy.
• Review of clinical features and diagnostic workup.
• Comparison with typical peripheral nerve palsy presentation.

Main Results:

• The patient presented with symptoms mimicking peripheral radial nerve palsy.
• Initial computed tomography scan was normal, increasing the risk of misdiagnosis.
• Detailed history and neurological examination were crucial for correct diagnosis.

Conclusions:

• Cerebral infarction should be a key differential diagnosis for sensory-motor deficits presenting as isolated peripheral nerve patterns.
• A comprehensive medical history and physical examination are essential to distinguish stroke from peripheral neuropathy.
• Prompt and accurate diagnosis of stroke is critical to prevent delayed treatment.
