Increased hip bone mineral density in a woman with gluteal silicon implant.

Conditions and artifacts such as aortic calcification, osteophytes, hip prostheses, and metallic objects can mislead the results of dual energy X-ray absorptiometry (DXA) scanning of the spine and hip. Gluteal silicon implants increasingly are being used for aesthetic purposes by women in Brazil, some of whom are at an age of high risk for the development of postmenopausal osteoporosis. We herein report a case of a woman whose hip bone mineral density by DXA clearly increased after the placement of bilateral gluteal implants of silicon. This case demonstrates the importance of inquiring about the presence of this artifact to avoid unnecessary evaluation of hip bone densitometry in these situations.
