Aspergilloma

It is one of the most common form of aspergillosis. It is made up of hyphae conglomerate, mucus, fibrin and inflammatory cells in a pre-existing cavity in the lungs.

Clinical presentation
The conglomerate can move within the cavity, but usually does not penetrate the surrounding parenchyma or blood vessels. The lesions usually remain permanent, sometimes they may shrink or spontaneously disappear, they may enlarge rarely. In some cases, they can cause heavy bleeding by damaging the bronchial vessels or the vessels surrounding the cavities. Predisposing factors for the development of aspergilloma can be previously made pathological cavities, such as conditions after tuberculosis, sarcoidosis, bronchiectasis, bronchial cysts, ankylosing spondylitis or lung infections.

Symptoms
Most patients will present with hemoptysis, which can be mild but also life-threatening. Other symptoms include cough, dyspnoea and fever.

Diagnostics
The diagnosis is based on an X-ray or CT scan of the chest, which shows the site of lung lesion. Sputum culture is positive in only 50% of cases, whereas IgG antibodies against A. fumigatus are present in most of the cases.

Treatment
Treatment is started when the patient is symptomatic, especially after the progress of haemoptysis. The drug of choice is itraconazole. Surgical resection of aspergilloma is commonly indicated for recurrent hemoptysis. Bronchial artery embolization is recommended in patients with life-threatening hemoptysis.
