Answer

Most complications are related to treatment. IVIG can lead to aseptic meningitis, thromboembolic events, and kidney failure; cyclophosphamide can lead to myelosuppression, hemorrhagic cystitis, and bladder carcinoma.

Rarely, patients develop phrenic nerve involvement leading to respiratory insufficiency. [15]
