Tietze syndrome is an inflammatory arthropathy of costochondral junction characterized by chest pain, tenderness and swelling. We reported the case of a 35-year-old worker with post traumatic Tietze syndrome. He had a history of two occupational chest traumas. They both occurred in the third left costo-chondral joint. Chest computed tomography showed located osteolysis. Differential diagnoses were excluded. He was treated with non-steroidal anti-inflammatory drugs and analgesics. As for partial permanent disability, we suggested 17% given the importance of the pain and its impact on mobility. Tietze syndrome diagnosis was based on eliminating differential diagnoses. This study raises knowledge about post-traumatic etiology in Tietze syndrome. A better understanding of this pathology could help practitioners with patients facing chest wall pain.

Rosai-Dorfman disease (RDD) is an uncommon lymphoproliferative disorder; RDD with oropharyngeal involvement is extremely rare, especially in adults. A 65-year-old woman with a complaint of progressive dyspnoea since 2016 presented with laryngeal involvement of RDD. A laryngoscopy examination revealed two solid, polypoid masses in the subglottic region, and a laryngeal biopsy concluded chronic in ammation without signs of malignancy. A second biopsy of axillary lymph nodes was performed, supporting the diagnosis of histiocytosis. The patient was treated with corticosteroids and then lost to follow-up. In 2019, she suffered from dyspnoea and a hoarse voice. Laryngoscopy examination showed a polypoid lesion causing airway obstruction at 70% and thickening of the lateral wall of the cavum. Physical examination found left axillary and submandibular adenopathy, and computed tomography revealed thickening of the supraglottic larynx narrowing the laryngeal pathway. Lymphadenectomy with immunohistochemical analysis revealed typical protein positive S-100 histiocytes and emperipolesis. The patient was treated with high doses of corticosteroids for six weeks then these were progressively decreased. The outcome was favourable; the laryngeal lesion disappeared after two weeks of treatment.

Recent studies about anterior cruciate ligament (ACL) surgery have focused on a better control of rotational stability, but ACL reconstruction is always a topical issue. The purpose of our study was to evaluate clinical and radiological outcomes after the use of the technique for anatomical reconstruction of the ACL with fascia lata, according to Macintosh technique modified by J.H Jaeger. We conducted a study of a continuous series of 80 patients between 2005 and 2019. All patients were assessed according to the International Knee Documentation Committee (IKDC) score and the Lysholm and Tegner scale. All our patients were rated as excellent with an average score of 92. Occasional lateral residual pain was reported by 8 patients. Residual jerk accounted for 2.5%. Radiological examination did not show ballooning or arthrosis at the last follow-up. Anterior cruciate ligament reconstruction is a common procedure that has become more reliable over time. But pivot shift (Jerk test) requires a lateral tenodesis "external rotation", especially in athletes.

Monteggia's fracture-dislocation is rare in pediatric traumatology and pose a problem of elapsed time before management and of prognosis. The purpose of this study was to describe the epidemiological features of this fracture and to assess functional and anatomical results. We report a series of 40 cases of Monteggia fracture in children whose data were collected and treated at the Habib Bourguiba University Hospital Center in Sfax over a period of 17 years, from January 1998 to January 2015. We listed the epidemiological data of our population as well as the types of fracture dislocations according to the Bado radiological classifications. For functional assessment, the choice of treatment was based on the type of fracture. P. Rigault's score and Kim's score were used. The average age of our study population was 8 years; 20 cases of fractures were classified as Bado I and 12 cases as Bado III. The time elapsed before treatment was less than 24 hours in 82% of cases. Surgical treatment was performed in 28 cases, and functional results were judged to be good in 30 cases. Our results were satisfactory due to the short time elapsed before patient management compared to literature data.

The diagnosis of right-sided infective endocarditis (RSIE) is often challenging. A positive outcome depends on rapid diagnosis, accurate risk stratification, and thorough follow-up. Imaging plays a key role in achieving these steps. We report the case of a 50-year-old male with diabetes insipidus, hypertension and renal failure. He had history of intravenous drug misuse. Transesophageal echocardiography (TEE) was performed and revealed an oscillating mass over the leaflets of the tricuspid valve and moderate tricuspid regurgitation. The chest computed tomography (CT) scan revealed septic pulmonary embolism with pulmonary infarctions. Retrospectively, ECG-gated multidetector-row CT revealed thickening of the tricuspid valve leaflets, dilated right atrium, and pericardial effusion. The patient was diagnosed with right-sided endocarditis and septic pulmonary embolism. He was medically treated without surgical intervention. This report aims to demonstrate the pivotal role of radiologic findings in infectious endocarditis (IE), both in the diagnostic phase and in the evaluation of the dispersion of the infection.

Lipomas are a common pathology. Their localization in the hand and fingers is rare. They are sometimes aesthetically embarrassing or when associated with signs of nerve irritation. The contribution of imaging makes it possible to suspect the benignity of the lesion. The treatment is surgical based on excision. We present five cases of lipomas of the hand, and we try to develop its different clinical and paraclinical peculiarities and the therapeutic modalities of this entity.
