The planar images of technetium-99m methoxyisobutylisonitrile of the neck and chest (upper row) showed an incidental finding of focal uptake at right breast (arrow). Noncontrast computed tomography of the chest (middle row) demonstrated a 1.3-cm breast nodule at right breast corresponding with the technetium-99m methoxyisobutylisonitrile lesion. Further inspection of the corresponding fusion images of single-photon emission computed tomography and computed tomography (lower row) showed nonfunctioning breast nodule

In addition, there was an incidental finding of a mild MIBI-avid 1.3-cm right breast nodule [Figure 1].
A correlative ultrasonography confirmed the presence of mass with spiculated margins, 1.5 cm x 0.7 cm at the right breast

Further investigations including mammography and ultrasonography of the breast were performed that reported a spiculated mass about 1.5 cm x 0.7 cm in the right breast categorized as Breast Imaging-Reporting and Data System (BI-RADS) 5, highly suggestive of malignancy [Figure 2].
