A Case of Radioactivity Concentrated in Orbital Implant in 99mTc-MDP Bone Scan and SPECT/CTCai, Min, MD; Feng, Guisheng, BA; Zhang, Guangwei, BAClinical Nuclear Medicine: December 2018 - Volume 43 - Issue 12 - p e453–e454 doi: 10.1097/RLU.0000000000002277 Interesting Images Abstract Author InformationAuthors Article MetricsMetrics A 27-year-old woman, who has received a hydroxyapatite orbital implant in the right eye due to a trauma 6 years ago, was newly diagnosis with left breast invasive ductal carcinoma. 99mTc-MDP bone scan showed an increased radiotracer accumulation in the right orbit and SPECT/CT confirmed the focal accumulation at the site of the implant, without any sign of local malignant lesions or orbital infection. Radionuclide imaging could provide certain useful information in diagnosing or differential diagnosing orbital disease.
