A 61-year-old man with lung cancer who underwent Tc-99m MDP bone scintigraphy for staging of the disease is presented. Tc-99m MDP bone scintigraphy was initially read as normal for the patient's age and a left metatarsal bone uptake was interpreted as a benign process. Magnetic resonance imaging of the left foot performed a few months later due to local pain revealed a lesion at the base of the third metatarsal. The surgical excision of this region showed a metastasis from a lung cancer.
