Objective: To evaluate the value of 16-slice multi-detector CT (MDCT) in the diagnosis of tumor-like bronchial tuberculosis.
Methods: Twenty-five patients with tumor-like bronchial tuberculosis underwent 16-slice CT scanning and the CT data were analyzed.
Results: Tumor-like bronchial tuberculosis were classified into 4 types according to the imaging features, namely intra-lumen nodule, intra-lumen mass, compression from outside of the bronchial lumens, and lung hilum mass. Tumor-like bronchial tuberculosis was featured by irregular bronchial wall thickening which led to decreased internal diameter of the bronchi with the external diameter remaining unchanged, ring-shaped enhancement, and absence of clear boundaries between the lesion and normal bronchi.
Conclusion: 16-slice MDCT can be advantageous in displaying tumor-like bronchial tuberculosis, and axial scan with 16-slice spiral CT combined with image reconstruction allows detection of the lesions inside the trachea and bronchus.

Article Synopsis
- Asymptomatic bronchial artery aneurysms (BAA) are rare but potentially fatal if they rupture, and the best treatment is bronchial artery embolization (BAE), which is minimally invasive.
- A 74-year-old man was diagnosed with a mediastinal BAA after a CT scan showed a suspicious lesion, but during BAE, complications led to acute aortic dissection, requiring urgent surgical repair.
- The situation highlighted the need for a flexible treatment approach, suggesting that TEVAR could be a viable option for BAA in challenging cases, ensuring prompt responses to complications like aortic dissection.

Carbon black nanoparticles (CBNPs) have been demonstrated to induce DNA damage in epithelial cells. However, the potential of the damage to initiate carcinogenesis and the underlying mechanism remain poorly understood. Therefore, we constructed an in vitro model of malignant transformation of human bronchial epithelial cells (16HBE-T) by treating 40 μg/mL CBNPs for 120 passages.
