A cervical spine injury caused bilateral occipital lobe infarction, leading to a rare visual field defect called crossed-quadrant homonymous hemianopsia. This case report highlights the clinicopathological correlation and imaging characteristics of this condition.

Area of Science:

Neurology
Ophthalmology
Radiology

Background:

Cervical spine injuries can rarely lead to complex neurological deficits.
Understanding the correlation between spinal trauma and visual field defects is crucial for diagnosis and management.

Observation:

A patient presented with crossed-quadrant homonymous hemianopsia, a specific type of visual field loss.
The visual defect was anatomically linked to bilateral occipital lobe infarction.

Findings:

Magnetic resonance imaging (MRI) revealed bilateral occipital lobe infarction.
The infarction pattern correlated precisely with the observed crossed-quadrant homonymous hemianopsia, demonstrating a clear clinicopathological link.

Implications:

This case underscores the importance of comprehensive neuro-ophthalmological evaluation following cervical spine trauma.
The findings contribute to the understanding of rare visual field defects and their underlying neuropathology.
Advanced imaging techniques like MRI are vital in characterizing such rare neurological presentations.
