Abstract
Abstract Aspergillus is a ubiquitous saprophytic mold that humans and animals constantly inhale. In health, the conidia are eliminated by the innate immune system. However, a subset of individuals with risk factors such as neutropenia, receiving high doses of glucocorticoids or certain biologicals, and recipients of hematopoietic or solid-organ transplants develop invasive aspergillosis. The mortality associated with invasive aspergillosis is 42%–64%. The early diagnosis of invasive pulmonary aspergillosis in patients without classical risk factors remains challenging. We present a case of an elderly female with uncontrolled diabetes mellitus who presented with acute-onset chest pain, breathlessness, and cough without expectoration. On evaluation, her chest radiograph showed a mass lesion in the right upper zone. 18Fluorodeoxyglucose (FDG)-positron emission tomography-computed tomography showed two FDG-avid lesions in the apical and medial segment of the right upper lobe. The lung biopsy was negative for malignancy; however, she was diagnosed with invasive pulmonary aspergillosis based on serum and bronchoalveolar fluid galactomannan positivity. She was managed with voriconazole with complete resolution of the lesion.
