[Pulmonary aspergilloma, diagnosis and treatment].
Pulmonary aspergilloma is a saprophytic form of aspergillosis, and the diagnosis is usually based on radiological findings such as thickened cavitary wall and fungus ball, and on positive serum antibody. Up to 58% of the patients with aspergilloma in Japan have medical history of tuberculosis. Serum anti-Aspergillus antigen is almost always positive in aspergilloma patients but aspergillus antigen is usually negative. Massive hemoptysis can be a fatal complication of aspergilloma, and the most common complication was respiratory failure according to our study. Surgical resection is the only promising intervention to cure the aspergilloma, however, low pulmonary function does not allow operation. Antifungal treatment is chosen for those who are out of operation indication, but the efficacy of antifungal treatment against aspergilloma is controversial. Some patients with aspergilloma show progressive form, and we define such aspergillosis as CNPA, chronic necrotizing aspergillosis, although the original entity of CNPA by Binder et al. is different. We make a diagnosis of CNPA only if all the following entity meets, 1; progressive shadows in radiological findings regardless of the presence of aspergilloma, 2; have some symptoms such as cough, sputum, hemosputum, hemoptysis or fever, 3; proof of Aspergillus attribution by mycological or pathological examination, 4; positive systemic inflammatory reaction, 5; neglect of other etiology of pulmonary diseases. Since CNPA is usually progressive, patients with CNPA should be treated with antifungals.
