case_images: Myocardial scan showing severely reduced tracer uptake in the inferior and inferolateral segments after dipyridamole infusion. Rest images showing significant but incomplete improvement in these segments. Interfering activity inferior to the left ventricle is also appreciated

case_images: There was a large, partially reversible defect in the basal to apical lateral and apical anterior left ventricular (LV) myocardial segments and apex [Figure 1], with associated reduced wall motion and systolic thickening.
case_images: Focal tracer uptake is seen in the right anterior chest. Tumor-to-background ratio at rest (right) is 5.6, marginally higher than 5.1 taken poststress. Possible explanations include greater myocardial tracer extraction after dipyridamole infusion with consequently decreased tracer available to the tumor, and increased uptake time in the rest image protocol allowed for greater lesion tracer accumulation against increased background washout

case_images: Raw and cine loop images showed a focus of increased tracer accumulation on the right chest [Figure 2].
case_images: (a) Low-dose computed tomography images provide adequate anatomic detail on the nodular masses seen in both breasts. (b) An axial slice taken from the single-photon emission computed tomography data set shows a dense focus of tracer accumulation and another less intense and more diffuse area of uptake in the right and left breasts, respectively. (c) The fused images showed that the breast masses are sestamibi-avid, with the right tumor showing greater uptake. Sternal uptake is at the same level as that in the vertebral body. (d) The maximum intensity projection is a three-dimensional rendering of the single-photon emission computed tomography dataset

case_images: Short-axis slices confirmed the sestamibi-avid focus on the right, as well as milder and more diffuse uptake on the left, anterior-anterolateral to the LV myocardium [Figure 3].
