Transesophageal echocardiographic observation of multiple myeloma involving the pericardium: a case report.

This report presents a case of multiple myeloma with a mass lesion on the pericardium and pericardial effusion. The response to intrapericardial combination chemotherapy (cisplatin and betamethasone) was evaluated by repeated transesophageal echocardiograms. Following the treatment, complete resolution of the tumor and effusion were observed for 6 months after which the patient died of bacterial pneumonia. Intrapericardial combination chemotherapy can be an effective treatment for myelomatous involvement of the pericardium.
