Occult breast cancer detection with technetium-99m-sestamibi: a case report.

چکیده
A 74-y-old woman with a 4-y history of left arm lymphedema and multiple negative mammography studies presented to her physician with a palpable subcutaneous nodule in the left upper arm. After biopsy the nodule was read pathologically as secondary breast carcinoma. We report a finding of a positive 99mTc-sestamibi scintimammography in the presence of an unremarkable mammogram. The study also revealed a positive uptake in a metastatic lesion in the manubrium of the sternum.

However, in patients with symptoms, other types of imaging play an important role in the detection of malignancies. The high cost and lack of availability of PET and MRI largely precludes the use in this patient population. TI-201 is nbt the imaging agent of choice because of its wash-out and redistri...
