ORTEGA HRESCAK, M.C. et al. Xantoma intraóseo pelviano: reporte de un caso y revisión de la literatura. Rev. argent. radiol. [online]. 2014, vol.78, n.3, pp.161-167. ISSN 1852-9992.

Abstract Intraosseous xanthoma is an extremely rare benign bone tumor. Histology shows mononuclear macrophages, abundant foam cells and multinucleated giant cells. The intraosseous xanthoma may appear associated with other diseases (secondary intraosseous xanthoma), mainly lipid disorders or without an underlying lipid disorder (primary intraosseous xanthoma). The intraosseous xanthoma is a lytic, expansive tumor, often seen in patients with hyperlipidemic conditions. In most cases, the initial evaluation is performed with X-ray, although other procedures may be necessary to confirm the diagnosis. We report the case of a man aged 48, who consulted for back pain radiating to the right leg and functional disability 3 months duration, with imaging findings in the right iliac XIO in the absence of pre-existing injuries or hyperlipidemic conditions, so surgery for total removal of the tumor was performed with histological examination of the surgical specimen, confirming the preoperative diagnosis of XIO. Such treatment resulted curative. The aim of this article is to describe the clinical, imaging findings (RX, MRI, CT, nuclear medicine) and the course of treatment of a committing the iliac primary intraosseous xanthoma a and a normolipidemic patient brief review of the literature.
