A 65-year-old female patient, with a known history of pleomorphic soft tissue carcinoma G3 at the proximal end of the right thigh, had undergone neo-adjuvant combined radio-chemotherapy, followed by resection and prosthetic replacement. A follow-up MRI showed a vague contrast enhancing mass lateral to the prosthesis. The image visualization however, was compromised by the metal artifacts. A CT-guided biopsy was requested for a histopathological diagnosis of scar versus recurrent tumor tissue.
