Metallosis: A diagnosis not only in patients with metal-on-metal prostheses Catarina A. Oliveira, Isabel S. Candelária, Pedro B. Oliveira, Antonio Figueiredo, Filipe Caseiro-Alves European Journal of Radiology Open Volume 2, Pages 3-6 (January 2015) DOI: 10.1016/j.ejro.2014.11.001 Copyright © 2014 Terms and Conditions

Fig. 1 A 55-years-old man with metallosis. Plain film of pelvis, revealing two round high-density images, one denser projected on the right iliac bone and the other above the right femoral neck (arrows). High density fragments adjacent to the inferior acetabular border were also noted (arrowhead). There is also an eccentric position of the femoral head in the acetabular dome (non equal distance between the femoral head margin and the acetabular border – trace lines).

Fig. 3 A 55-years-old man with metallosis. CT findings revealed a large elongated collection of high-density content, extending from the articular space into the pelvis along the right psoas muscle, in relation to metallic components debris.
