A 74-year-old man underwent lung scintigraphy to rule out pulmonary embolism. Planar images revealed an abnormal midline uptake of ^99mTc macroaggregated albumin (MAA), which localized to several thoracic vertebrae, as revealed by single photon emission computed tomography / computed tomography. Contrast-enhanced computed tomography demonstrated stenosis of the left brachiocephalic vein for median sternotomy. By vascular stenosis, vessels to the vertebrae developed as a collateral pathway. Additionally, ^99mTc MAA was administered from the left median cubital vein in this patient.
