A Complex Cardiac Mass Originating from Interatrial Septum in a Patient with History of Kidney Cancer: A Case Report and Literature Review

Figure 1

(a–c) PET scan images demonstrate increased uptake within nodes in the aortic pulmonary window, left hilum, and a mass in the left upper lung. (d) Transesophageal echocardiography shows large cardiac mass invaded to the intra-atrial septum and right and left atrium with cystic lesion protruding to the left atrium. (e–g) MRI with and without contrast shows multiple enhancing neoplastic masses in the muscle compartment in both lower extremities which are believed to be due to metastatic lesions.
