Abstract
An 81-year-old man was hospitalized as a result of a urinary tract infection. Three-phase bone scintigraphy was performed because of intermittent shoulder soreness. Immediately after the intravenous bolus injection of 740 MBq (20 mCi) Tc-99m methylene diphosphonate, the sequential 4-second anterior images, 16 in total, revealed tubular tracer accumulation over the anterior left mediastinal region. Nevertheless, no bone abnormality was found on delayed bone scintigraphy. Therefore, the authors presumed that the tubular tracer accumulation was an aortic dissection. Chest computed tomography performed the following day confirmed that the patient did have an aortic dissection from the arch to the descending aorta.
