Surgical Treatment of Intrapelvic Pseudotumour after Hip Resurfacing Arthroplasty: Case Report and Literature Review

Figure 3

In the metal artefact reduction sequence magnetic resonance imaging (MARS MRI), axial T1 (a), axial T2 (b), and sagittal T1 (c) show the presence of two lesions of thick walls located anterior to the psoas and iliacus (arrows) muscle. Within the lesion, a small focus of artefact is seen (arrow heads). This finding is critical to determining that the aetiology of the pseudotumour is “metallosis.”
