RADIOPHARMACEUTICAL: 99mTc MDP, 835 MBq
A triple-phase bone scan of the lower limbs, whole body blood pool images together with delayed whole body images were obtained.
On the dynamic and blood pool phase, intense perfusion involving the left tibia is seen. Intense perfusion to the left femur and acetabulum and left ASIS is also noted.
On the delayed whole body images, focal areas of intense tracer uptake involving the left acetabulum and ASIS, entire left femur and left tibia is identified.
Conclusion: The scintigraphic findings are consistent with fibrous dysplasia involving the left hemipelvis and left lower limb as described.
