Ekstravasation af kontrast efter koronarangiografi kan forveksles med subaraknoidalblödning på
CT
Sammanfattning
Brain parenchymal extravasation of contrast has been described after infusion of larger amounts of iodinated X-ray contrast agent. We describe a case in which a patient after infusion of 500 ml iomeprole 350 mg/ml developed neurological symptoms and a subsequent cerebral computed tomography (CT) scan was interpreted as subarachnoid haemorrhage. The patient was fully recovered within 48 hours, and a follow-up CT scan 26 hours later showed no signs of haemorrhage. In patients with sudden onset of neurological symptoms after infusion of large quantities of contrast media and a CT scan showing signs of subarachnoid haemorrhage, spinal puncture or magnetic resonance imaging should be considered prior to interventional procedures in order to verify the diagnosis.
