文摘

Ionic contrast, if accidentally injected into the intrathecal space during routine imaging studies or interventional procedures, may significantly interfere with neuronal activity, potentially causing ascending tonic-clonic seizure syndrome and even death. As a result, ionic contrast is strictly contraindicated for intrathecal use. Rapid recognition of the condition followed by prompt management, typically involving aggressive cerebrospinal fluid (CSF) drainage, is critical to improving patient outcome. Lumbar drain has previously been well described as a management strategy.Case DescriptionWe present a case of accidental intrathecal injection of an ionic contrast agent, iothalamate meglumine, in a patient undergoing cervical epidural steroid injection. This patient was managed successfully with drainage of CSF using an external ventricular drain alone.ConclusionOur literature review and analysis of the previously published cases demonstrate that aggressive CSF drainage is essential to improve outcomes, and in some cases an external ventricular drain alone may be effectively used.
