Transdiaphragmatic invasion of pleural mesothelioma

Case contributed by Chris O'Donnell


Known pleural mesothelioma presenting with abdominal distension and discomfort

Patient Data

Age: 80
Gender: Male

Multiple solid tumor nodules are present in the left lung base. They are pleurally-based and represent deposits of mesothelioma. They are both lateral and in the posterior costophrenic sulcus with subtle but definite penetration of tumor through the diaphragm (arrows) into the left subphrenic space as well as extending into the chest wall posteriorly (arrow). This is associated with considerable edema and thickening of the omentum together with increased vascularity and ascites.

Case Discussion

Mesothelioma is one of the few tumors that crosses anatomical planes - such as the chest wall and diaphram.  In this case both have occurred!
