A 65-year-old man arrives at the emergency department after experiencing hemoptysis early this morning. The patient believes he coughed up around 100 mL of blood. He had been in his typical condition of health and felt good before to this event, with no fevers, night sweats, or weight loss. Over the last three months, he has had bouts of blood-tinged sputum. For tuberculosis (TB) that was successfully treated some years ago, the patient's prior medical history is crucial. He smoked a pack of cigarettes every day for 45 years until quitting four years ago. A example CT scan cut, shown below, shows alterations consistent with past TB infection, including an aged left upper lobe. Compared to prior scans, the main difference is that the cavity now appears to be filled with a round mass. Which of the following best describes this patient's condition?

Eductional Objective: Aspergillus fumigatus is responsible for a wide range of diseases. In immunocompromised and neutropenic individuals, it can be an opportunistic infection (invasive pulmonary aspergillosis). Aspergillosis can colonize (aspergilloma) a preexisting lung cavity by forming a fungus ball. It can also induce lung hypersensitivity in those with asthma who have allergic bronchopulmonary aspergillosis.
