Bronchiale Aspergillosen

[Overview: granulomatous diseases of the lung]

The spectrum of pulmonary granulomatoses is wide and includes infectious and noninfectious entities, each with very different therapeutic consequences. The first step of histological examination discriminates between necrotizing and non-necrotizing granulomatosis. After this, an infectious cause of the granulomatosis has to be excluded by special histological stains and molecular-pathologic methods, if necessary. Diagnosis also includes clinical, radiological, and microbiological findings. The process of pathological examination should be standardized as described.

Pulmonary aspergilloma: clinical aspects and surgical treatment outcome

Aspergillomas are fungal balls within lung cavities. The natural history is variable. Hemoptysis is a dangerous sequela. Medical therapy is ineffective because of the lack of a lesion blood supply. Randomized trials are lacking. Surgery should be the treatment of choice in cases of hemoptysis, and even in asymptomatic patients, if lung function is not severely compromised. Cavernostomy and cavernoplasty may be options for high-risk patients. Percutaneous therapy should be reserved for patients who are not fit for surgery. Bronchial artery embolization is appropriate for symptomatic patients not suitable for surgery. Embolization could be considered a preoperative and temporary strategy.

Endobronchial aspergilloma: report of 10 cases and literature review

PURPOSE

A retrospective investigation of the clinical and radiologic features as well as the bronchoscopic appearance was carried out in patients with endobronchial aspergilloma.

MATERIALS AND METHODS

Ten patients with endobronchial aspergilloma diagnosed by bronchoscopy and histological examination were identified at the Gyeongsang University Hospital of Korea, from May 2003 to May 2009.

RESULTS

The patients included 9 men and 1 woman, and the age of the patients ranged from 36 to 76 (median, 58 years). The associated diseases or conditions were: previous pulmonary tuberculosis in 7 patients, lung cancer in 2 patients, pulmonary resection in 1 patient, and foreign body of the bronchus in 1 patient. The chest radiologic finding showed fibrotic changes as a consequence of previous tuberculosis infection in 6 patients and a mass-like lesion in 2 patients. Two patients had a co-existing fungus ball, and an endobronchial lesion was suspected in only 2 patients on the CT scan. The bronchoscopic appearance was a whitish to yellow necrotic mass causing bronchial obstruction in 7 patients, foreign body with adjacent granulation tissue and whitish necrotic tissue in 1 patient, whitish necrotic tissue at an anastomosis site in 1 patient, and a protruding mass with whitish necrotic tissue in 1 patient.

CONCLUSION

An endobronchial aspergilloma is a rare presentation of pulmonary aspergilosis and is usually incidentally found in immunocompetent patients with underlying lung disease. It usually appears as a necrotic mass causing bronchial obstruction on bronchoscopy and can be confirmed by biopsy.
