An incidentally detected solitary fibrous tumor on (99m)Tc-sestamibi myocardial perfusion imaging.

A 55-year-old woman with a mild transient chest pain but normal laboratory examination results underwent Tc-sestamibi myocardial perfusion imaging. An abnormal nodular radioactive uptake, which appeared protruding from the anterior segments, was detected. This activity was later proved to be benign solitary fibrous tumor of pleura after histopathological examination after the surgical exploration.
