A bony sequestrum is a single piece of bone present in an area of osteolysis. It is separated from the surrounding bone and is primarily observed in patients with bone infection. We present our radiographic findings on 18F-FDG PET/CT in a case of esophageal squamous cell carcinoma with a sequestrum in the skull metastasis.
