Objective To summarize the clinical features, predisposing factors, diagnosis, therapeutic outcome, and prognosis of invasive pulmonary fungal infection( IPFI) . Methods 90 cases with pathologically proved IPFI, admitted in non-intensive care unit in Xiangya Hospital from January 2005 to February 2012, were retrospectively analyzed. Results The pathogenic examination revealed Aspergillosis in 56 cases( 62. 2% ) , Cryptococcus in 18 cases( 20. 0% ) , Mucormycosis in 6 cases( 6. 7% ) , and Histoplasma in 6 cases( 6. 7% ) , etc. The underlying diseases were reported in 87 cases, and mainly included COPD, pulmonary tuberculosis, and diabetes mellitus. Cough and expectoration were the common clinical symptoms. 49 patients ( 54. 4% ) received long-term and broad-spectrum antibiotic therapy. The CT results revealed masses type in 25 cases( 27. 8%) , nodule lesions type in 15 cases( 16. 7% ) , lung consolidation type in 22 cases( 24. 4% ) , cavity type in 22 cases( 24. 4% ) , aspergilloma type in 6 cases( 6. 7% ) . 47 patients were clinical diagnosed with IPFI before biopsy with preliminary diagnosis accordance rate of 52. 2% . 31 cases ( 34. 4% ) underwent surgical resection of pulmonary lesions, and no recurrence was detected over two-year follow up. 56 cases ( 62. 2% ) received systemic anti-fugal therapy, and 43 cases( 76. 8% ) were cured or significantly improved. 3 cases ( 3. 3% ) refused any therapy. Conclusions The most frequently isolated pathogen of IPFI is Aspergillosis. The mainly underlying diseases are COPD, pulmonary tuberculosis, and diabetes mellitus. Long-termand broad-spectrum antibiotic therapy may be the major risk factor. Pathological examination is needed for final diagnosis. Surgical procedure can achieve optimal prognosis.
