Imaging in prostate cancer is important in defining the local extent of disease, nodal involvement, and identifying metastases. Bone scan is the most commonly used modality for identification of bone metastasis in prostate cancer despite its reported low sensitivity and specificity compared to magnetic resonance imaging (MRI) which is the imaging gold standard for bone metastasis. Gallium-68 prostate-specific membrane antigen positron emission tomography-computed tomography (68Ga PSMA PET-CT) imaging is a relatively new addition to the imaging modalities in prostate cancer. This is a report of a patient with high-risk prostate cancer with features consistent with skeletal metastases on MRI but negative for skeletal metastases on bone scan and 68Ga PSMA PET CT. Histology confirmed the absence of skeletal metastases.
