Abstract:
A case of fibrocalcifying pseudotumor occuring at a very unusual site, the intraosseous region of axis, is presented. Previous reports of similar lesions in skull base, intracranial parenchyme, soft tissue around spine, mediastinum, and pleura have been described under the designation 'fibro-osseouslesions' and 'calcifying pseudoneoplasm' The etiology, pathogenesis and natural course of the lesion are still unknown. Bvt the lesion is probably benign nature and reactive lesion rather than neo-plastic. Authors performed resection of lamina, spinous process, and a portion of pedicles and occipitocervical fusion to prevent spinal cord compression due to cortical expansion or fracture. Microscopically, amorphous, basophilic, hyaline, and chondroid calcifying masses were rimmed by palisading histiocytes and foreign body-type giant cells. No evidence of malignancy was found.
