Diagnosis With Brief Discussion
- Diagnosis
- Necrotizing granulomatous (Semi-invasive) aspergillus pneumonia
- Radiologic Findings
- Chest radiograph shows slowly gorwing multiple nodules in both lungs over 50 days. High resolution CT shows multiple nodules and mass with internal cavity formation. Transthoracic needle aspiration biopsy was performed on RUL cavitary nodule. Photomicrographs of specimen with H&E, GMS stains reveal many branching fungal organism, morphologically consistent with aspergillosis.
- Brief Review
- Semi-invasive aspergillosis, also known as chronic necrotizing aspergillosis, is characterized at histologic analysis by the presence of tissue necrosis and granulomatous inflammation. Factors associated with the development of this form of aspergillosis include underlying pulmonary disease such as chronic obstructive lung disese, a history of pulmonary tuberculosis, cystic lung disease, pneumoconiosis and mild systemic immunodeficiency such as diabetes mellitus, malnutrition. alcoholism, advanced age, prolonged corticosteroid therapy.
Clinical symptoms are often insidious and include chronic cough, sputum production, fever, and constitutional symptoms. Hemoptysis has been reported in 15% of affected patients.
Radiologic manifestations of semi-invasive aspergillosis include unilateral or bilateral segmental areas of consolidation with or without cavitation or adjacent pleural thickening, and multiple nodular areas of increased opacity. The fidings progress slowly over months or years.
