Left Lung Neoplasms and Bilateral Pleural Effusion Combined Elevated Carcinoembryonic Antigen in Pleural Effusion with Negative Result of Thoracoscopy Pleural Biopsy Misdiagnosed as Lung Carcinoma Ultimately Confirmed Pulmonary Sarcomatoid Carcinoma by CT-guided Percutaneous Lung Biopsy: a Case Report and Literature Review |
Background: Detection of carcinoembryonic Antigen (CEA) in pleural effusion has good clinical application value in differentiating benign and malignant pleural effusion, but sometimes CEA provides limited help. We report a case of a patient with left lung neoplasms combined with bilateral pleural effusion with increased CEA in the pleural effusion whose thoracoscopy pleural biopsy pathology was negative, mimicking lung carcinoma and ultimately confirmed as pulmonary sarcomatoid carcinoma by CT-guided percutaneous lung biopsy.
