(A) Friable erythematous nodule of left medial leg. (B) Sagittal positron emission tomography with computed tomography with avid uptake in the same nodule of left leg (arrow).
Figure 2
(A) Mass-like right atrial filling defect (arrow) demonstrated on transverse contrast computed tomography (CT). (B) Right atrial mass (arrow) redemonstrated on sagittal contrast CT encasing pacemaker leads. (C) Prechemotherapy positron emission tomography with computed tomography (PET-CT) demonstrating avid uptake of a right atrial mass (arrow) encasing pacemaker leads in transverse view. (D) PET-CT demonstrating complete metabolic response (arrow) post-treatment in transverse view.
Figure 3
(A) Apical four-chamber view on transthoracic echocardiogram did not show any evidence of mass or thrombus in the RA. (B) Mid-esophageal bicaval view on transesophageal echocardiogram shows the mass extending from the superior vena cava into the RA along the device lead. RA: right atrium; LA: left atrium; IVC: inferior vena cava; M: mass; SVC: superior vena cava
Figure 4
(A) Gadolinium cardiac magnetic resonance imaging in transverse view showing heterogeneous hyperenhancement of right atrial mass (arrow) occupying the right atrium, with right ventricle, left atrium, and left ventricle. (B) Same right atrial mass (arrow) redemonstrated in sagittal view with RV and aorta. RA: right atrium; RV: right ventricle; LV: left ventricle; LA: left atrium; Ao: aorta
