Background: The differential diagnosis of exudative pleural effusion is a major challenge for chest physicians particularly in a country with limited financial resources.
Objective: The aim of this study was to evaluate the role of the sonographic features in the prediction of exudative malignant pleural effusion.
Design: This was a prospective cross-sectional study.
Setting: This study was carried out between May 2013 and June 2014 in the Chest Department of Assiut University Hospital.
Patients: The patients enrolled included 25 patients with malignant pleural effusion and 25 patients with other different benign causes.
Main outcome measures: The sonographic appearances of pleural effusions were defined in terms of five patterns: anechoic, complex septated, complex nonseptated, pleural thickening, and pleural nodules.
Results: Among the 25 malignant exudative pleural effusions, a complex nonseptated pattern is a useful diagnostic predictor, with sensitivity, specificity, positive predictive value, and negative predictive value of 60, 68, 65, and 63%, respectively. Pleural nodules were only found in malignant effusion (100% specificity). If we define the complex septated sonographic pattern as a predictor for benign effusion, we can achieve sensitivity, specificity, positive predictive value, and negative predictive value of 52, 88, 81, and 65%, respectively.
Conclusion: Pleural nodules and a complex nonseptated pattern in the sonographic appearance are useful predictors of malignant pleural effusions, whereas a complex septated pattern is a useful predictor in nonmalignant effusion. |
