Differentialdiagnose von Rundherden nach Lungentransplantation
2008
: Incidence, aetiology, diagnosis and treatment of round lesions in the lungs were analysed in 64 patients after lung transplantation (33 men, 31 women; mean age 45 [21-68] years; postoperative survival > 2 weeks). These lesions were found in 8 patients 1-10 months (median of 5.8 months) after the transplantation, singly in two, multiple in six. In six patients it was an incidental finding, further elucidated by computed tomography or fine-needle biopsy. The aetiology varied from B-cell "lymphoma" (posttransplant lymphoproliferative disorder-PTLD) in three patients, aspergilloma in two, and bacterial abscess in one. Two patients died of septicaemia (Aspergillus; Pseudomonas aeruginosa/Staphylococcus aureus), while four had a full remission. The solitary lesions disappeared without specific treatment in 2-3 weeks. If round lesions are noted after lung transplantation, rapid histological and microbiological diagnosis and aggressive treatment are necessary to combat an otherwise high death-rate. PTLD and infection (bacterial or mycotic) are the most frequent causes.
