Background. Niemann-Pick Disease (NPD) type B is a rare autosomal recessive disease characterised by hepatosplenomegaly and pulmonary disease, highlighted by preserved volumes and diminished diffusion capacity of the lung for carbon monoxide (DLCO) on pulmonary function tests (PFTs). There is no current accepted treatment for the disease. We present a case of a successful bilateral lung transplant in a patient with a DLCO of 14%, and significant pulmonary changes attributable to NPD type B on computed tomography (CT) chest, and both microscopic and macroscopic assessment of the lung explant. To the author’s knowledge this is only the third case of lung transplantation in a patient with NPD type B and is one of two current living patients post lung transplantation for NPD type B. Case Report. A 64-year-old male patient underwent bilateral lung transplantation for NPD type B. Preoperative PFTs demonstrated preserved volumes with significantly decreased DLCO, with imaging showing a diffuse reticular interstitial pattern, typical of chronic fibrotic lung disease. The patient suffered from primary graft dysfunction type 3 in the postoperative period as well as rejection managed with methylprednisolone and intravenous immunoglobulin. The patient improved steadily and was discharged 80 days post-transplantation. Conclusions. This case is only the third reported case of lung transplantation in a patient with NPD type B and the second case of a patient with NPD type B currently living post-transplantation, being at postoperative day (POD) 267 at the time of manuscript drafting. It demonstrates that lung transplantation, although hazardous, is a viable strategy for treatment in patients with NPD type B who have significant pulmonary involvement.
