When in Doubt, Add SPECT/CT: A Case of Mistaken Identity

(A) Suggestive distal sternal focus on whole-body anterior planar bone scintigraphy. In addition to degenerative and physiologic uptake, intense focus is seen overlying distal sternum. (B) Intense distal sternal focus overlying distal sternum, possibly external to patient, on right anterior oblique spot bone scintigraphy of chest. (C) Unmasking of identity of sternal focus on axial SPECT/CT, which reveals that focus of radiopharmaceutical is external to patient, overlying needleless hub lying on chest of patient. This finding confirmed possible external uptake seen on right anterior oblique imaging.
