Cardiophrenic angel nodes: an unusual CT finding of advanced metastatic disease.

Computed tomography (CT) is increasingly being used in the chest and mediastinum. In the mediastinum it is used to distinguish benign from malignant lesions, such as metastatic nodes from benign mediastinal fat deposits (1, 2). These abnormalities are usually first seen on a routine chest film. However, nodal enlargement involving the cardiophrenic angle nodes may or may not be seen on routine chest roentgenograms, depending on the size and location of the lesion. The purpose of this report is to demonstrate the CT findings of advanced metastatic disease involving the cardiophrenic angle nodes. The possible clinical significance of these findings is discussed.
