Rare case of an extraosseous cervical chordoma with both intradural and extensive extraspinal involvement
Background Chordomas must be considered among the differential diagnoses for extradural spinal tumors, especially involving the clival or sacrococcygeal regions. They are often locally invasive and destructive to the osseous structures from which they arise, but rarely extend intradurally. Here, we report a unique chordoma that was intradural and spanned nearly four subaxial cervical vertebral ...
متن کاملExtraosseous chordoma of the nasopharynx.
BACKGROUND AND PURPOSE Chordoma is a relatively rare tumor of the skull base and sacrum thought to originate from embryonic remnants of the notochord. Chordomas arising from the skull base/clivus are typically locally aggressive with lytic bone destruction. When chordomas occur in an extraosseous location, they may mimic other lesions of the nasopharynx. We present 5 cases of primarily extraoss...

In this case report, we describe an extraosseous chordoma in the coccygeal region that later metastasized to the cerebellum. A 30-year-old man presented with a progressively enlarged lesion in the coccygeal region with painful sensation. Preoperative computed tomography and magnetic resonance imaging showed a large lobular mass in the coccygeal region without sacrococcygeal destruction. Patholo...
متن کاملChordoma in Nasopharynx in a 70-Year-Old Female: A Rare Occurence
The nasopharynx is an unusual site for extraosseous chordoma. The characteristic histology and immunohistochemistry confirmed the diagnosis. The behaviour of this tumour is locally aggressive. We report a case of nasopharyngeal chordoma in an elderly patient with literature review.
