We report a case of extraadrenal retroperitoneal paraganglioma in a 24-year-old female. This case is unusual in that the neoplasm showed extensive calcification, osseous metaplasia, and marrow elements. Although calcification may occur in paragangliomas, to the best of our knowledge, osseous metaplasia with marrow elements have not been previously reported in the English literature.
