Abstract
Background
Pulmonary lymphangitic carcinomatosis (PLC) is a rare secondary metastatic cancer. Cough and dyspnea are the common clinical manifestations of PLC. PLC is often confused with pulmonary sarcoidosis, pulmonary edema, pneumoconiosis, and interstitial pneumonia, which leads to delayed diagnosis and poor prognosis.
Case Presentation
A 23-year-old female with a cough. Gastric cancer was confirmed by gastroscopy. The abnormal changes in the lung were considered to be consistent with PLC.
Conclusion
PCL is often misdiagnosed or delayed. PLC should be considered when cough, dyspnea, and chest CT show thickening of the peribronchovascular and interlobular septa or when pleural effusion and enlargement of mediastinal lymph nodes.
