Easy interpretation of heterotopic ossification demonstrated on bone SPECT/CT.
A 29-year-old male patient suffered from paraplegia 6 months after brain injury. Heterotopic ossification was diagnosed based on clinical characteristics such as decreased range of motion at the bilateral hips without infective signs. A planar bone scintigraphy using Tc-MDP showed intensive radiotracer accumulation in the proximal portion of the bilateral femurs and the right acetabulum. The SPECT/CT images showed increased radiotracer accumulation in the adjacent soft tissues of the bilateral hips but not in the bone. The conservative treatment rather than surgical intervention was given according to the findings in bone SPECT/CT images.
