Chronic osteomyelitis in children is frequent in the developing countries. Their complications and morbidity burden the functional prognosis. The reconstruction of diaphyseal bone loss after sequestrectomy in young children remains a difficult and expensive challenge in our context. The delay in care and the lack of social security for all, are risk factors for morbidity. The induced membrane technique described by Masquelet starts to be applied and showed satisfactory results. We report the results of a case of reconstruction of the proximal humerus by using a non-vascularized fibula and supplemental bone substitute in a boy of 2 years with sickle cell. No scarring occurred at the sampling site. The process of bone consolidation is underway.

Stafne’s Bone Defect in Atypical Location: Between the Subcondylar Region and Neck of the Mandible Ramus

引用

Open Journal of Medical Imaging 2017年第3期7卷 124-129页

CONTEXT: Stafne’s bone defect is a benign lesion appearing on the image as a round radiolucent lesion within a cortical defect on the mandible. CASE REPORT: We attend one 46-year-old male patient came for diagnostic evaluation of a rounded and radiolucent lesion in the transition of the subcondylar region and neck of the left mandible ramus incidentally found by a dentist. Computed tomography and magnetic resonance imaging were performed in medical radiology and a Stafne’s cyst was diagnosed in an atypical location. CONCLUSION: We emphasize that Stafne’s bone defect is a benign lesion, whose imaging diagnosis can be conclusive, avoiding unnecessary surgical procedures.

Silver nitrate mimicking a foreign body in the pharyngeal mucosal space

引用

World Journal of Radiology 2015年第5期7卷 100-103页

Silver nitrate is sometimes used as a means of chemicalcauterization for control of minor bleeding and management of hypergranulation tissue following bedside head and neck procedures. There are only few reports available on the imaging appearance of silver nitrate and its potential to mimic a foreign body. We report a case of a patient presenting with dysphagia, odynophagia, and fever following dental work who had a peritonsillar incision and drainage for treatment of a deep neck space infection. During the procedure, silver nitrate was applied to halt the bleeding. Patient was subsequently transferred to another institution. Since the patient was not showing significant clinical improvement on antibiotic therapy, a computed tomography(CT) scan was performed demonstrating a hyperdense structure lodged in the pharyngeal mucosal space in the oropharynx and soft palate that was mistaken for a foreign body such as bone. Silver nitrate can have density similar to bone but does not have the normal architecture of bone with cortex and marrow on CT. Familiarity with the appearance of silver nitrate on CT, lack of bone architecture, and proper documentation and communication of the use of silver nitrate to the consultant radiologist and medical personnel could help avoid misdiagnosis and potentially unnecessary surgical exploration.
