Her past medical history included a 43 pack‐year smoking history, chronic obstructive pulmonary disease, hypertension, dyslipidaemia, diabetes mellitus and obesity. She had resided in Malaysia for almost three years as a child and had previously travelled to Papua New Guinea several years before presentation. A lung lesion was incidentally detected while the patient was undergoing imaging to investigate hepatic steatosis. She had no clinical features of infection or malignancy.
