Whole body bone scan is commonly used to detect bone metastases in these patients. Bone scan findings are sensitive for detecting metastases but with less experience and especially without the use of single photon emission computed tomography/computed tomography (SPECT/CT) images, they are less specific. This means that while bone scans are effective at identifying areas of abnormal bone activity, they may not always distinguish between bone metastases and other conditions, such as fractures, infections, or benign bone diseases such as a rare condition like osteopetrosis, leading to potential false positives. This 52-year-old male patient was referred for a whole-body bone scan for evaluation of bone metastasis. At first glance, the scan pattern with multiple foci of increased radiotracer uptake seemed to indicate bone metastases due to the patient's colon cancer.
