Incidental Detection of Asymptomatic Brain Metastases on 18F-fluoride Positron Emission Tomography/Computed Tomography and 68Ga DOTANOC Positron Emission Tomography/Computed Tomography in a Patient with Concomitant Breast Carcinoma and a Pancreatic Neuroendocrine Tumor

World J Nucl Med. 2018 Jan-Mar;17(1):65-66. doi: 10.4103/wjnm.WJNM_10_17.

Abstract

A 54-year-old female treated for locally advanced ductal breast carcinoma was also diagnosed with a pancreatic neuroendocrine tumour. A staging 68Ga DOTANOC positron emission tomography/computed tomography (PET/CT) demonstrated somatostatin receptor-positive foci within the brain parenchyma. A whole body 18F-fluoride PET/CT also demonstrated several foci of low-grade tracer uptake in the brain. Magnetic resonance imaging confirmed several cerebral and cerebellar metastases. This case highlights the need to be aware of each tumor's metastatic profile and the careful attention required for thoroughly evaluating imaging in the presence of multiple pathologies. Furthermore, such incidental findings can have significant treatment and prognostic implications.
