Abstract:

Most symmetric radiotracer accumulation in the skeleton found in bone scintigraphy is thought to be non-specific or benign cause. Solitary symmetric bone metastasis is rare and often misinterpreted. Other image modalities or biopsy are usually needed to differentiate malignant metastasis from benign cause. The authors report a case of bladder cancer with pubic bone metastasis. The bone scan showed symmetric uptake in bilateral pubic bones mimicking the typical appearance of osteitis pubis. However, the pelvic CT scan showed bone metastasis to symphysis pubis.
