A 72-Year-Old Man With Innumerable Bilateral Pulmonary Nodules After Lung Transplantation.

Area of Science:

• Medicine
• Immunology
• Transplantation

Background:

• Lung transplantation is a life-saving procedure for end-stage lung disease.
• Immunosuppression is critical to prevent organ rejection but increases infection risk.

Observation:

• A 72-year-old bilateral orthotropic lung transplant recipient presented with cough, dyspnea, and back pain 6 months post-transplant.
• The patient had a complex serostatus for cytomegalovirus (CMV) and Epstein-Barr virus (EBV) with the donor and recipient.
• He was on a standard immunosuppressive regimen including tacrolimus, mycophenolate mofetil, and prednisone.

Findings:

• The patient's presentation suggests a potential post-transplant complication.
• Differential diagnoses include infection, rejection, or other inflammatory processes.
• Further investigation is needed to determine the etiology of the symptoms.

Implications:

• This case underscores the importance of vigilant monitoring for complications in lung transplant recipients.
• Understanding donor-recipient serostatus for viruses like CMV and EBV is crucial.
• Timely diagnosis and management are essential for favorable outcomes in transplant patients.
