Myositis ossificans circumscripta is a benign lesion characterized by focal heterotopic soft tissue ossification, occurring in young people generally after localized trauma. Clinical and radiological appearances may mimic a sarcomatous neoplastic process. We report a case of myositis ossificans occurring after trauma, so as to illustrate the different imaging features of this benign pathology on conventional radiographs and computed tomography.

Chondrosarcoma is a rare cartilaginous tumor, representing less than 0,5% of intracranial tumors. This tumor occurs primarily in elderly patients and involves long and pelvic bones. The authors report a case of intracerebral chondrosarcoma in a 12 year old child, probably fronto-ethmoidal in origin. CT and MR imaging showed a lytic partly calcified soft tissue mass.

A study of 36 cases of vertebral and spinal cord hydatidosis seen between 1970 and 1984 allowed their division into three groups: those with purely intravertebral lesions, vertebral hydatid osteopathy, and hydatid pseudo-Pott's affections. The contribution of conventional radiology is reviewed at length and the importance of computed tomography emphasized for screening of extension and surveillance of "white cancer", a term applied by Deve to bone hydatidosis. Use of the scanner for CT imaging makes screening for residual or recurrent lesions a radiologic exploration.
