Bleeding developed postoperatively and was investigated using pulmonary CT angiography, which failed to identify a site of active bleeding. 99mTc-labeled red blood cell (RBC) SPECT/CT of the chest was performed, and the site was rapidly located. To our knowledge, this is the first case reported in the literature of localization of intrathoracic bleeding using 99mTc-RBC SPECT/CT.
