Non-tuberculous mycobacteria (NTM), other than Mycobacterium tuberculosis (TB) may produce pulmonary infection. NTMI is typically an indolent infection except in immunocompromised and HIV infected patients. Imaging plays a crucial role in suggesting NTMI as a possible diagnosis in this patient population. Always consider classic or cavitary NTMI in patients with upper lobe cavitary disease similar to active cavitary TB. However, in such cases TB must always be excluded. In elderly white women, persistent right middle lobe/lingular atelectasis, bronchiectasis or consolidation should suggest the diagnosis of bronchiectactic NTMI. In patients with imaging findings of subacute hypersensitivity pneumonitis, the radiologist must review the history and consult with the clinician in order to identify the triggering allergen, including NTM which is associated with indoor hot tubs.

Nontuberculous Mycobacterial Infection

Here we report the case of a 72-year-old woman with nodular bronchiectaticMycobacterium aviumcomplex (MAC) disease. Chest computed tomography on admission revealed multiple micronodular and branching opacities in both lobes with segmental distribution; bronchiectasis and bronchial wall thickening were observed in the middle lobe and lingula. The patient consented to and underwent thoracoscopic lung biopsy; epithelioid granulomas were occasionally observed, but follicular bronchiolitis was widespread. While bronchial lesions from nontuberculous mycobacterial infection generally present as epitheliod granulomas, the present case suggests that follicular bronchiolitis can also be a histological counterpart to nodular opacities in nodular bronchiectatic MAC disease.

Pulmonary carcinoids originate from neuroendocrine cells of the lung and comprise 0.5%–5% of all lung malignancies. Endobronchial carcinoids are rare, low-grade malignant tumors that occasionally coexist with other infectious diseases, including tuberculosis and nontuberculous mycobacterial infection. We treated a 63-year-old woman who presented with a right middle lobe obstruction. A chest computed tomography scan demonstrated a mass-like lesion in the right middle lobe with mediastinal lymphadenopathy. She underwent an exploratory operation after 2 weeks of antibiotic treatment. The pathology revealed a right middle lobe bronchial carcinoid tumor and aspergillosis. Chest computed tomography scans have revealed no recurrence of the carcinoid or aspergillosis during the 5-year follow-up.

Abstract We report the thoracoscopic RS5 segmentectomy with VVBA (V, vein; V, ventilation; B, bronchus; A, artery) method and confirmed that the segmental plane visualized by vein-first resection is slightly narrower than the traditional artery-first resection.
