Cementoplasty of metastases of the proximal femur: is it a safe palliative option?

Purpose: Percutaneous cementoplasty has proved very effective for the palliation of pain from bone metastases. However, several studies argue that it should be contraindicated for metastases that are located in the proximal femur because of inadequate bone consolidation. The aim of this study was to evaluate the risk factors for fracture despite performing cementoplasty for metastases of the proximal femur.

Primary intracranial extraskeletal myxoid chondrosarcoma.

Extraskeletal myxoid chondrosarcomas (EMC) are extremely rare and are usually located in the deep soft tissues of the lower extremities. Less than 10 cases of intracranial EMC have been reported in the literature, making their management and early diagnosis difficult. We present a new case of intracranial EMC occurring in a 70-year-old woman presenting with a right frontal mass initially assumed to be a brain metastasis from breast adenocarcinoma.
