CTICasesSmall Cell Lung Carcinoma with Multi-Nerve Compression
Imaging findings
Chest CT shows a large mediastinal mass diagnosed as small cell lung carcinoma, causing complete obstruction of the left superior pulmonary vein, leading to left upper lobe interstitial edema. Voice change and left diaphragmatic elevation correspond to recurrent laryngeal nerve invasion and phrenic nerve atrophy.
Key takeaways
Large central lung cancers can cause vascular and neurological compression. Recurrent laryngeal nerve paralysis results in vocal cord medialization, while phrenic nerve compression causes diaphragmatic elevation. Obstructing a pulmonary vein causes localized interstitial edema mimicking lymphangitic spread.
