Myositis ossificans of the chest wall.

We report the unusual case of a young man with progressive pain in the thoracic wall. The radionuclide bone scan revealed an increased uptake, and the bone roentgenogram, a calcified soft-tissue mass. Based on computed tomography findings, biopsy was avoided, and evolution was favourable for myositis ossificans. Although rare, myositis ossificans is one of the potential causes of thoracic pain, not to be mistaken for a malignant or infectious lesion

L’ostéome ostéoïde intra-articulaire du coude : une pathologie rare mimant une synovite inflammatoire chez un jeune patient. Diagnostic et traitement

L’ostéome ostéoïde est une tumeur osseuse atteignant majoritairement les os longs des membres inférieurs (les fémurs et les tibias dans 75% des cas) et le rachis. La localisation intra- ou périarticulaire compliquée d’une arthrite et d’un déficit de la mobilisation est rare, notamment au niveau de la palette humérale du coude (1), raison pour laquelle le diagnostic est souvent malaisé à établir et retardé. Nous rapportons le cas d’un patient de 16 ans, chez lequel une ablation percutanée par radiofréquence a été réalisée avec succès

Dramatic response of synovitis, acne, pustulosis, hyperostosis, and osteitis syndrome to tofacitinib monotherapy: a case report.

The synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is a rare condition. Its treatment remains a challenge for clinicians, and often yields mixed results. We report the case of a 51-year-old Caucasian woman who presented with SAPHO syndrome with mainly axial involvement. She had been treated with sulfasalazine and anti-inflammatory drugs for many years without any success. A few weeks after starting treatment with tofacitinib, both clinical and biological parameters dramatically improved. Imaging also showed considerable regression of the vertebral and pelvic lesions. However, tofacitinib had to be discontinued due to the occurrence of pulmonary embolism. Consequently, recurrence of bone pain and biologic inflammation was rapidly observed. Anti-JAKs are an interesting treatment option in the management of SAPHO syndrome that need further clinical trials and assessment for validating response

[Imaging evaluation of cervical spine trauma].

Evaluation and treatment of patients with suspected cervical vertebral trauma requires close cooperation between multiple medical disciplines. Recognition of the significant signs of cervical spine injury enables accurate interpretation of the radiograph, and if necessary adequate selection of the best imaging method for further evaluation. When judiciously selected, these imaging techniques result in the expeditious gathering of the diagnostic information required for the management of the traumatized patient

Adult onset of multifocal eosinophilic granuloma of bone: a long-term follow-up with evaluation of various treatment options and spontaneous healing

We report a case of multifocal-monosystemic Langerhans cell histiocytosis (LCH), formerly usually referred to as eosinophilic granuloma (EG) of bone. The condition developed in a 36-year-old man. A notable infrequent thoracic spine location and two successive distinct costal lesions were observed. Both the first costal site and the vertebral location healed spontaneously; the second costal lesion underwent biopsy resection. The patient's disease course with an 8-year follow-up is discussed with reference to various treatment options, emphasising in selected cases a watchful conservative approach, in view of the widely documented potential for spontaneous healing
