Abstract :
Background: Cardiac risk assessment with myocardial perfusion imaging
(MPI) is a common practice for some elderly breast cancer patients who are
candidates for operation. In rare cases the tumor may become visible in the images.
Case presentation: This is the report of a case with a huge slow-growing breast
tumor suspicious for malignancy and presenting with methoxy-isobutyl-isonitrile
(MIBI) uptake in the tumor. The patient was referred to the nuclear medicine
department for preoperative cardiac risk assessment with MPI.
Conclusion: There was high uptake in the tumor was note worthy in two
different aspects: 1)high MIBI uptake in the tumor is more suggestive of malignant
rather than benign tumors and thus, underscores the importance of extra-cardiac
uptake sites in pre-operation MPI; and 2)high uptake in the left breast tumor may
obscure the MPI image and hinder proper interpretation.
