D. Aspergillosis
Pathology results from supraglottic biopsy revealed branching, fungal microorganisms among superficial fragments of squamous epithelium. Culture and bronchoalveolar lavage results confirmed the diagnosis of Aspergillosis laryngotracheobronchitis.
Aspergillus tracheobronchitis (ATB) is an unusual form of pulmonary aspergillosis that is seen in fewer than 10% of aspergillosis-related cases.1 Patients with neutropenia and/or who are immunocompromised are at particular risk for ATB.2 Patients usually present with dyspnea, cough, and wheezing. Diagnosis of this rare entity is often delayed because of its nonspecific clinical presentation and lack of radiographic findings at early stages.3 Radiologic findings may include thickening of airways, patchy infiltrates, or no findings at all.1 Definitive diagnosis requires visualization with laryngoscopy or bronchoscopy and both pathological and microbiological biopsies.4
