Intravenous immunoglobulin (IVIG) is a safe treatment to treat various neurological disorders, but fatal thrombotic events as rare complications have been reported.

To the best of our knowledge, this is the first case of pulmonary thromboembolism associated with IVIG treatment in a Korean patient with Guillain-Barre syndrome.
