Intraoperative high-field magnetic resonance imaging combined with neuronavigation-guided resection of intracranial mesenchymal chondrosarcoma in Broca's area: a rare case report and literature review.

Cranial Mesenchymal chondrosarcoma (MC) and those that occurred in brain parenchymal were fairly rare aggressive neoplasm commonly affecting the bone of young adults. Here, we reported a case with intracranial MC, invading Broca's area, a rare site not previously reported, which was presumed to be a glioma. We performed a gross total resection guided by intra-operative magnetic resonance imaging (iMRI) combined with neuronavigation. Follow-up shows no language and other brain function loss. Furthermore, we present a review of literature. We emphasized the importance of gross total resection guiding by the combination of iMRI and neuronavigation, which was proved to be both reliable and effective in language preservation.
