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.
