Diagnosis With Brief Discussion
- Diagnosis
- Invasive pulmonary aspergillosis
- Radiologic Findings
- Chest X-ray shows consolidation in RLLF. CT shows a 4.3 cm oval shape ill-defined subpleural non-enhancing mass with internal air density in RLL. And 3 cm irregular enhancing mass in LLL. There was no pleural effusion or enlarged mediastinal lymph nodes.
- Brief Review
- Chronic pulmonary aspergillosis (CPA) is an uncommon and problematic pulmonary disease, complicating many other respiratory disorders, thought to affect ∼240000 people in Europe. The most common form of CPA is chronic cavitary pulmonary aspergillosis (CCPA), which untreated may progress to chronic fibrosing pulmonary aspergillosis. Less common manifestations include: Aspergillus nodule and single aspergilloma. All these entities are found in non-immunocompromised patients with prior or current lung disease. Subacute invasive pulmonary aspergillosis (SAIA, formerly called chronic necrotising pulmonary aspergillosis) is a more rapidly progressive infection (<3 months) usually found in moderately immunocompromised patients, which should be managed as invasive aspergillosis. Recommendations of approach to the radiographic diagnosis of invasive pulmonary aspergillosis is the below;
Recommended performing a chest computed tomographic (CT) scan is whenever there is a clinical suspicion for IPA regardless of chest radiograph results (strong recommendation; high-quality evidence). Routine use of contrast during a chest CT scan for a suspicion of IPA is not recommended (strong recommendation; moderate-quality evidence). Contrast is recommended when a nodule or a mass is close to a large vessel (strong recommendation; moderate-quality evidence). Suggested a follow-up chest CT scan is to assess the response of IPA to treatment after a minimum of 2 weeks of treatment; earlier assessment is indicated if the patient clinically deteriorates (weak recommendation; low-quality evidence). When a nodule is close to a large vessel, more frequent monitoring may be required (weak recommendation; low-quality evidence).
