RT Journal Article SR Electronic T1 Penile Implant on Bone Scan Imaging: A Case Study JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol.

YR 2002 UL http://tech.snmjournals.org/content/30/3/128.abstract AB We present an unusual case of the incidental finding of a penile implant on a whole-body bone scan obtained for back pain in a patient with osteoporosis and vertebral body fractures. On 2 separate occasions, this patient underwent 3-h delayed whole-body bone scanning with 99mTc-methylene diphosphonate. The images showed acute and then subacute vertebral body fractures. On both imaging occasions, the bone scan that included the region of the implant clearly showed the penis, but visualization was better on the second scan. Penile implants have not been described in the nuclear medicine literature, and it is important to recognize the diagnostic possibilities when penile photopenia is identified.
