Abstrakt
Atrial fibrillation (A-fib) is the most common cardiac arrhythmia which is associated with an increased risk of mortality secondary to stroke and coronary artery disease. Intravenous glucocorticoid therapy (such as dexamethasone and hydrocortisone) is frequently used peri-operatively in patients undergoing cardiac surgery to prevent A-fib. Dexamethasone is also frequently used in patients with single or bilateral vestibular schwannomas (VS), to reduce tumor swelling both before and after radiation treatment. We describe a case of A-fib in a 50 year-old female patient with neurofibromatosis type 2 (NF-2), who was prescribed dexamethasone for post-radiation tumor edema.
