A case of vertebral artery dissection diagnosed using gadolinium-based contrast agent in a patient with iodine allergy

Key Points

• The aim is to highlight the effective diagnosis of vertebral artery dissection using gadolinium-based contrast in a patient with an iodine allergy.
• Conducted multiple CT scans for spleen injury evaluation despite iodine allergy.
• Performed MRI due to dual vision occurring five years post-trauma.
• Used gadolinium contrast for cerebral angiography to identify vascular issues.
• Identified cerebral infarction in the right middle cerebral artery via MRI.
• Detected vertebral artery dissection through gadolinium-enhanced angiography.
• Demonstrated potential for gadolinium contrast in cases with a history of iodine allergy.
