Presentation
Patient with known metastatic prostate cancer, had nuclear medicine bone scan to assess baseline prior to commencing chemotherapy.
Patient Data
Extensive osteoblastic metastases involving axial and appendicular skeletons.
An osteoblastic lesion is also identified in the left frontal skull and upper cervical spine.
Bilaterally proximal femur osteoblastic lesions evident.
Case Discussion
The extensive innumerable osteoblastic metastases involving the axial and appendicular skeletons resulting in a superscan appearance.
The superscan imaging appearance occurs as a result of a high ratio of bone to soft tissue tracer accumulation. Intense osteoblastic activity in the bones causes diminished renal and background soft tissue uptake, which is as seen in the images above.
