Repeated, severe headache in a lung transplant patient: a case report.

We report a patient in whom a double lung transplantation has been performed for end-stage bronchiectasis due to IgG2 deficiency, under treatment with monthly intravenous immunoglobulins (IVIG) and Later switched to subcutaneous (SC) IG on her request. After the transplantation procedure which was uneventful, she continued to receive weekly SCIG. She developed repeated episodes of aseptic meningitis, which was finally resolved by switching again to monthly IVIG (slower infusion rate) in combination with low dose sodium valproate. This is to our knowledge the first case of aseptic meningitis due to SC IG treatment after lung transplantation.
