Metrizamide myelography risk factors: a pseudopsychiatric case presentation
Abstract:
A case of neurologic sequelae from intrathecal metrizamide is presented. The patient had a convulsion, became comatose, and transiently developed mutism and hemiparesis, with eventual full recovery. Metrizamide is generally safe, but side effects do occur, and they may require clinical attention and follow-up.
Insights
Intrathecal metrizamide can cause serious neurologic side effects, including seizures and coma, though full recovery is possible. This case highlights the need for clinical attention and follow-up for adverse events.
Area of Science:
- Neurology
- Radiology
- Pharmacology
Background:
- Intrathecal contrast agents are used in neuroimaging.
- Metrizamide is a non-ionic, water-soluble contrast medium.
- Adverse neurologic events following intrathecal administration are rare but significant.
