Chronic necrotizing pulmonary aspergillosis successfully diagnosed, treated, and followed by ultrathin bronchoscope
Abstract:
We present a case of chronic necrotising pulmonary aspergillosis (CNPA) successfully diagnosed, treated and followed by ultrathin bronchoscope. A 68-year-old man was admitted to the hospital because of a cough and low-grade fever. A chest computerized tomography (CT) showed cavitary infiltrates in the superior segment of the left upper lobe. Bronchoscopic examination was performed using a 2.8-mm ultrathin bronchoscope, which could be inserted into the cavity lesion under direct vision. Biopsy specimens from a whitish intracavity lesion showed septate-branching hyphae and cultures of the cavital washing grew Aspergillus fumigatus. Using the ultrathin bronchoscope, we instilled amphotericin B into the cavity before oral itraconazole therapy. The patient showed clinical improvement with resolution of the cavitary infiltrates on CT findings. The whitish intracavity lesion had prominently disappeared after 18 months of therapy. An ultrathin bronchoscope is useful for treating and assessing cavity lesions as well as establishing a diagnosis for CNPA patients.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
