Aspergilloma and the surgeon.

Aspergillus fungus is a ubiquitous saprophyte that is the causative organism for the development of an aspergilloma. The most common species causing an aspergilloma is the Apergillus fumigatus. An aspergilloma is a conglomeration of mucus, inflammatory cells and altered blood elements. Aspergillomas typically form in pre-existing lung pathology, most notably and commonly in old healed tuberculosis cavities. They are classified into simple and complex types that have clinical relevance. Symptoms are very variable and it is not uncommon to incidentally find a lung aspergilloma. In most case series, the most common presenting symptom is haemoptysis which varies from mild to catastrophic bleeds. Given the limited information about the natural history of the disease, there is unfortunately no recognised factor or variable which can predict how an aspergilloma will manifest itself, hence the manner of treatment is a still a topic of debate among treating physicians. The mainstay of treatment is surgical intervention and medical options although disappointing at the current stage, require further investigation in light of the newer available anti-fungal agents. The need for surgical intervention is however not as clear-cut as one would like, since many patients have multiple co-morbidities and other diffuse or focal lung pathology, making the decision process indeterminate in certain instances. In this review, we focus on the different surgical options available for the management of aspergilloma across variable clinical settings, and we propose an approach to its management.
