[A state of confusion following cerebral angiography with iopamidol: a case report]

A 59-year-old male in a state of confusion following cerebral angiography with iopamidol was reported. He was admitted to our hospital for right upper monoparesis. MRI demonstrated multiple cerebral infarction. The patient had undergone angiographies with iopamidol, of which a total of 100 ml had been used. After the examination, the patient showed perseveration, continuing to say the same sentence and 30 minutes later he entered a state of confusion. He recovered completely from this consciousness disturbance after 30 hours. No lesion except for the old infarction was demonstrated on CT and MRI. Confusion in this case was assumed to be a toxic reaction caused by the contrast agent.
