Cortical metastasis - unusual type of skeletal metastatic disease. CT (upper) and SPECT/CT (lower) shows osteolytic full-thickness cortical lesion with extraosseous soft tissue component, moderate intramedullary spread, “Codman triangle” and increased radiotracer uptake at the periphery of the bone defect.
