A wide variety of infections can affect the chest wall including pyogenic, tuberculous, fungal, and some other unusual infections. These potentially life-threatening disorders are frequent especially among immunocompromised patients but often misdiagnosed by physical examination and radiographs. The purpose of this article is to describe the clinical and imaging features of these different chest wall infections according to the different imaging modalities with emphasis on ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). The outcome of chest wall infection depends on early diagnosis, severity of the immunosuppression, offending organism, and extent of infection. Because clinical findings and laboratory tests may be not contributive in immunocompromised patients, imaging plays an important role in the early detection and precise assessment of the disease. US, CT, and MRI are all useful: bone destruction is more accurately detected with CT whereas soft tissue involvement are better visualized with US and MRI. CT and US are also used to guide percutaneous biopsy and drainage procedures. MR images are helpful in pre-operative planning of extensive chest wall infections.

OBJECTIVE: The purpose of this article is to identify the typical imaging features of periosteal chondrosarcoma on radiography, CT, and MRI. CONCLUSION: Periosteal chondrosarcoma is a rare low-grade malignant cartilaginous tumor arising from the external surface of bone. Imaging features are often specific. Recognizing periosteal chondrosarcoma and differentiating it from other surface tumors is of capital importance because the prognosis is excellent after adequate local surgery alone.

Brucellosis is a zoonosis of worldwide distribution, relatively frequent in Mediterranean countries and in the Middle East. It is a systemic infection, caused by facultative intra-cellular bacteria of the genus Brucella, that can involve many organs and tissues. The spine is the most common site of musculoskeletal involvement, followed by the sacroiliac joints. The aim of this study was to assess the clinical, biological and imaging features of spinal brucellosis.

Idiopathic tumoral calcinosis is an unusual benign condition characterized by the presence of calcified soft tissue masses of varying size around the joints. In this retrospective study,clinical data and radiological features of nine cases of idiopathic tumoral calcinosis are reviewed. Imaging features, particularly magnetic resonance imaging findings are detailed.

Primary leiomyosarcoma of bone is a very rare tumor. Four cases are reported: 3 tumors were located in the femur and 1 in the talus. Clinical and imaging findings including radiographs, CT, and MRI are described. The final diagnosis was made by histopathological, immunohistochemical, and/or ultrastructural study after biopsy.
