[Diagnosis of peripheral cavitary squamous cell lung carcinoma with Aspergillus infection using LungPro navigation system: a case report].

ABSTRACT

Virtual bronchoscopic navigation (VBN) is increasingly being used to diagnose peripheral lung lesions, allowing precise guidance of the bronchoscope to the target lesions, thereby improving diagnostic accuracy. This paper reported a patient admitted due to hemoptysis, with an initial clinical diagnosis of squamous cell lung carcinoma with brain and bone metastases. Previous attempts had failed to obtain tissue samples from the lung lesions. Upon admission, the LungPro navigation system was used to perform a bronchoscopic transparenchymal nodule access (BTPNA). Pathological examination of the lung tissue and microbiological analysis of bronchoalveolar lavage fluid confirmed the diagnosis of peripheral cavitary squamous cell lung carcinoma with Aspergillus infection. Following antifungal and antineoplastic treatment, the patient's symptoms improved markedly and she was subsequently discharged.
