The Diagnostic Value of Transthoracic Ultrasonographic Features in Predicting Malignancy in Undiagnosed Pleural Effusions: A Prospective Observational Study

Abstract

In the presence of an undiagnosed pleural effusion, US morphological characteristics can aid in differentiating MPE from non-MPE. Pleural/diaphragmatic nodularity was the most relevant feature although no finding was pathognomonic of MPE.
