Mycologically confirmed chronic pulmonary aspergillosis in a post-pulmonary tuberculosis patient in Ghana.

UNLABELLED

Pulmonary tuberculosis (PTB) remains a major public health challenge in low- and middle-income countries. PTB may leave residual cavitation following treatment in some patients, allowing saprophytic colonization by Aspergillus species, resulting in a slow, progressive lung condition known as chronic pulmonary aspergillosis (CPA). PTB is the commonest underlying condition in CPA, mainly post-treatment. CPA is likely to be misdiagnosed as PTB reactivation due to clinical and radiological similarities. Ghana has a significant PTB burden, but only one case of clinically and radiologically diagnosed CPA has been reported, and epidemiological studies are also lacking. The definitive diagnosis of CPA comprises symptomatology, imaging findings and mycological evidence. Mycological evidence is critical to rule out other differential diagnoses, including non- pulmonary fungal infections and has implications for treatment choice. Herein, we present a case of mycologically-confirmed CPA in a previously treated PTB patient.
