Local recurrence of breast cancer demonstrated on 99mTc-MIBI scintigraphy.
We present a postmastectomy patient in whom a mass was palpated in the chest wall. It appeared to be difficult to determine whether the chest wall mass was local recurrence of breast cancer or granulation induced by mastectomy on computed tomography (CT). The mass was successfully demonstrated on 99mTc-methoxyisobutylisonitrile (99mTc-MIBI) scintigraphy as an area of increased accumulation, and was considered to be a recurrent tumor. Surgical resection was performed, and the mass was histopathologically proven to be recurrence. 99mTc-MIBI scintigraphy may contribute to the detection of local recurrence or distant metastasis in addition to the diagnosis of primary breast cancer and axillary metastasis.
