Figure 12.

(A) Lateral radiograph of the lower right leg shows a large elliptical lytic metastasis destroying the right anterior distal tibial diaphysis with overlying soft tissue mass (arrow) in a 72-year-old woman with endometrioid endometrial adenocarcinoma. Sagittal T1-weighted (B), axial pre-contrast T1-weighted (C), and axial post-contrast T1-weighted (D) MR images highlight the extent of the metastatic lesion destroying the distal tibia, with a large extra-osseous soft tissue mass (short arrow), cortical destruction (long arrow) and intramedullary extent. (On pathologic diagnosis, the soft tissue mass excision showed metastatic adenocarcinoma, morphologically consistent with recurrent endometrioid adenocarcinoma).
