Background: Popliteal artery entrapment syndrome is a common vascular pathology in young athletes which is usually diagnosed based on magnetic resonance angiography findings. Although three-phase bone scan is a sensitive imaging modality in high turnover osteoblastic conditions, it does not have an established role in evaluating chronic pain syndromes and vascular pathologies. Case Presentation: We report an atypical case of popliteal artery entrapment syndrome which was incidentally found in a patient who was evaluated for skeletal malignancy. Conclusion: This case emphasizes the importance of attention to the first two phases of bone scan despite normal whole body images.
