RT Journal Article SR Electronic T1 Diagnosis of Dual Malignancy by 18F-FDG PET/CT in the Setting of Paraneoplastic Cerebellar Degeneration JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 52 OP 53 DO 10.2967/jnmt.115.158659 VO 44 IS 1 A1 Thapa, Pradeep A1 Basu, Sandip YR 2016 UL http://tech.snmjournals.org/content/44/1/52.abstract AB We describe a rare case of paraneoplastic cerebellar degeneration (with detectable antineuronal antibody anti-Yo) in which 18F-FDG PET/CT aided in the detection of 2 synchronous malignancies (one thyroid cancer and the other breast cancer). Interestingly, the primary breast malignancy was non-18F-FDG–avid and was detected through the presence of a metastatic 18F-FDG–avid axillary lymph node. Surgery for both was undertaken in the same sitting, and there was improvement of the neurologic features soon after the surgical removal of the malignancies.
