Chronic recurrent multifocal osteomyelitis (CRMO) is a very rare condition of unknown etiology and most commonly occurs during childhood or adolescence. The purpose of this paper is to present a case of CRMO in a vertebral location with severe kyphosis, spinal cord compression, and neurological dysfunction requiring anterior decompression and fusion. After 12 weeks, the patient was physically able to return to school. At 2-year follow-up, neurological and functional outcomes are fair. Magnetic resonance imaging shows good restoration of the sagittal spine alignment despite residual mild kyphosis, and restoration of a normal sagittal diameter of the spinal canal.

Background Thromboembolic events frequently complicate the course of malignancy and represent a major cause of morbidity and mortality in cancer patients. In contrast to chemotherapy and other systemic therapies, little is known about the impact of ionizing radiations on the incidence of venous thromboembolism (VTE) in cancer patients. Methods In the present prospective study, we aimed to investigate the incidence, management, and outcome of VTE in newly diagnosed cancer patients who received curative radiotherapy. Results VTE was found in 8 patients, out of 401 patients at a median time of 80 days after radiotherapy initiation. The incidence rate of VTE at 6 months post‐treatment was 2% (95% CI, 0.9–3.7), with 50% of cases occurring during the radiotherapy course and 50% of cases in patients who received or were receiving chemotherapy. As none of the patients harbored a personal history of VTE, no prophylactic measure was initiated during cancer therapy. Most patients received monotherapy with low‐molecular‐weight heparin and were still on surveillance at the end of the study. No specific clinical risk factor was identified that might systematically indicate the need of thromboprophylaxis in the context of curative radiotherapy. Conclusions Although this pan ‐cancer descriptive study did not relate an increased risk of short‐term thrombosis following ionizing radiation, it provides important insight as a basis for future studies with subcategories of cancer, in order to in fine guide further recommendations in frail patients. Clinical trial registration number NCT02696447.
