Fibular findings in carcinoma prostate; a challenging situation for reporting physician

Prostate cancer (PC) is the second most common malignancy in men. According to International agency for research on cancer,4552 new cases of PC were registered in 2018 in Pakistan.Although majority of cases are confined to prostate on initial presentation, there is a high tendency for advanced PC to metastasize to bone. Metastatic lesions are typically osteoblastic rather than osteolytic. Therefore, these are easily identified by Technetium labeled Methylene Diphosphonate (Tc99m-MDP) uptake on Whole body Bone Scan (BS). Hybrid scanning offers anatomic details for differentiation between aggressive or non-aggressive lesions. Most common axial sites include pelvic bones and spine. Metastases to appendicular skeleton is rare and uncommon . We present a case of 62-years-old male with PC. Follow-up WBS, showed interval development of multiple sites of skeletal metastases. SPECT-CT scan acquired for characterization of atypical site of abnormal MDP uptake in appendicular skeleton, which showed features suggesting skeletal metastasis.
