Abstract:
Objective To explore the imaging characteristics of SAPHO syndrome in 11 cases.Methods Clinical features and imaging findings from 11 patients (6 male,5 female, 28 to 68 years old)with SAPHO syndrome were analyzed retrospectively Including DR in 9 cases, CT in 10 cases, MRI and radioisotope scanning in 3 cases. Results Multi-bones of anterior chest wall disorders were shown in 9cases on DR images including superior sternum , anterior first rib and clavicle hyperostosis. Bony fusion and bony bridge were also seen in these cases. Hyperostosis osteosclerosis, bone destruction and bony fusion of sternoclavicular articulation and first rib were shown on CT images in 9 cases. Osteosclerosis of the joint between manubrium and midsternum was seen in 1 case on CT image. Thc sign of flying sea gull was seen in 2 cases on axial anterior chest wall CT images. The disorders of anterior chest wall were bilateral in 8 cases and unilateral in 2 cases. Sacroiliitis and osteomyelitis of ilium were found accompanied in 1 case.Osteomyelitis of thoracic vertebrae were found in 2 cases, while sclerosing osteitis of lumbar vertebrae and ostearthritis of bilateral hands were observed respectively in 1 case. The thicken soft tissue surround clavicle head, thoracic vertebra disease with long T1 ,jumbly T2 and high fat suppression signal ,long T1 and short T2signal under sacroiliac joint were shown on MRI. Radioisotope scanning displayed higher radioactive uptake of radionuclides, with T shape in sternoclavicular area in 3 cases. Conclusions Multi-bones of anterior chest wall involvement was the common imaging characteristics in 11 patients. Sacroiliitis, osteomyelitis of vertebrae and ilium, sclerosing osteitis, ostearthritis of hand could be seen in some cases.
