A syndrome of synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) is a rare autoimmune disease. It occurs in genetically predisposed individuals by immune activation triggered by possible infectious agents. A 60-year-old man was presented with musculoskeletal and cutaneous manifestations. After exclusion of differential diagnoses, he was diagnosed with SAPHO and successfully treated with adalimumab. He had a typical image defined as a bull’s head sign in bone scintigraphy with 99mTc- methylene diphosphonate. Positron emission tomography also revealed increased inflammatory activity in related anterior chest joints and soft tissue. We want to emphasize diagnostic radiological images in patients with SAPHO to increase the awareness of clinicians.
