Cerebral Angiography using Gadolinium as an Alternative Contrast Medium in a Patient with Severe Allergy to Iodinated Contrast Medium

We report cerebral digital subtraction angiography (DSA) using Gadolinium in a patient allergic to iodinated contrast media. A 77-year-old woman was admitted to our hospital for surgical resection of a brain tumor. Although a DSA was requested as a preoperative examination, the patient had a history of allergic reaction to non-ionic iodinated contrast medium. Therefore, DSA was performed using Gadolinium. The DSA showed no tumor stain and normal venous drainage. The patient underwent surgical resection of the tumor and was discharged with no new neurological deficit. DSA using Gadolinium was useful in a patient with an anaphylactic reaction to iodinated contrast media.
