Three cases of extraosseous Ewing sarcoma are reported. This pathology of the young adult is very rare as shown by the review of the literature. Clinical or imaging (CT or MRI) findings are non-specific and diagnosis is based on histology. Nonetheless, this diagnosis should be considered in all patients with primary soft tissue tumors.

We present a case of symptomatic pneumatocyst of the ilium observed in a professional scuba diver exposed to pressure variations. Pneumatocysts are rare and except for one case reported in a clavicular localization, are always found in subchondral bone of the iliac or sacral side of the sacroiliac joint. Undoubtedly, air fills an intraosseous node. We report here the first case of efficient treatment achieved by filling the cyst via percutaneous access under scopic control.

Out of 137 cases concerning the spine and spine cord, the authors demonstrate that MRI is nowadays fully integrated in urgency investigations. In all cord compression suspicions and in spine trauma investigations, it's place is found. Coil and software improvements allow to put CT and MR scanning delays on a line. This study underlines the necessity of being equipped with non magnetic life support systems allowing management of very fragile patients. In traumas, MR provides the lesion's authentification, it's type, it's unique localisation or not, and therefore an early functional prognosis. The discovery of spine cord involving lesions in neoplastic conditions allows to follow a therapeutic strateging for maintaining the motor function. In the end, the authors discuss about practical utility of MR in scuba diving decompression accidents. No lesion of the spine cord has been demonstrated in 25 patients, probably because of technical insufficiency.
