Abstract
- A 37-year-old male patient was transferred from a local orthopedic clinic due to status epilepticus following a myelography with diatrizoate. On his laboratory findings, metabolic acidosis was prominent. Non-enhanced brain CT scan showed a high densinty in the subarchnoid space. With careful respiratory support, hydration, correction of acid-base balance, administration of dexamethasone, and anticonvulsant therapy, he completely recovered after 3 days. Diatrizoate is an ionic, iodinated and hyperosmolar X-ray contrast medium. It must not be injected intrathecally because of the risk to the central nervous system. The possible mechanisms are anaphylactic reaction due to iodine hypersensitivity, hyperosmolar effect, and direct chemotoxicity by ionicity and chemical structure itself.
