Concurrent or sequential chemoradiotherapy is considered an effective approach, and some targeted drugs have been clinically tested and demonstrated favourable results. We present a case of primary pulmonary NMC with cervical lymph node metastasis, in which the patient experienced temporary symptom relief after receiving anlotinib and chemotherapy combined with immunotherapy.

These cases highlight the importance of including mycobacterial infections such as tuberculoma in the differential diagnosis of solitary pulmonary nodules and stress the need for comprehensive microbiological evaluation in CBCT-confirmed biopsies, especially when histology is non-malignant.

We report a case of a persistent right upper lobe abscess due to invasive pulmonary infection that was successfully drained bronchoscopically. CBCT imaging enabled real-time, three-dimensional localisation and confirmation of needle placement within the abscess cavity.

This case highlights the potential for bronchoscopic intervention in the multidisciplinary management of complex pulmonary infections.
