Lymphatic plastic bronchitis and primary chylothorax: A study based on computed tomography lymphangiography

Figure 1 Flow diagram of study cohort. DLG: Direct lymphangiography; PB: Plastic bronchitis; CTL: Computed tomography lymphangiography.

Figure 2 A 34-year-old woman with primary chylothorax. A: The axial computed tomography lymphangiography (CTL) shows abnormal contrast medium accumulation in the thoracic duct outlet (long white arrow); B: A nonenhanced axial CT scan shows massive bilateral pleural effusions (black asterisk). Compressive atelectasis can be seen in both lungs (white asterisk); C: The CTL in the same plane as B shows abnormal contrast medium accumulation in the left pleura (black arrowhead), bilateral lung tissue (white arrowhead).

Figure 3 A 16-year-old woman with primary chylothorax. A: The contrast-enhanced thoracic axial mediastinal window shows diffuse mediastinal soft-tissue infiltration (long white arrow), right pleural effusion (short white arrow), left pleural thickening (white arrowhead); B: The computed tomography lymphangiography in the same plane as A shows abnormal contrast medium scattered in surrounding mediastinum (short black arrow).

Figure 4 A 28-year-old man with plastic bronchitis. The axial omputed tomography lymphangiography shows an abnormal contrast medium surrounding the right main bronchus (long white arrow), right hilar lung (short white arrow).

Figure 5 A 41-year-old woman with plastic bronchitis and primary chylothorax. A and B: The thoracic axial lung window shows interlobular septal thickening (long black arrow), bronchovascular bundles thickening (short black arrow), diffuse ground-glass opacities in pulmonary parenchyma (black asterisk).
