2024年9月10日 · Chordomas are uncommon malignant tumors of the axial skeleton that account for 1% of intracranial tumors and 4% of all primary bone tumors. They originate from embryonic remnants of the primitive notochord (earliest fetal axial skeleton, extending from the Rathke's pouch to the tip of the coccyx).
Chordoma | Radsource - Radsource: PACS Radiology Systems
Spinal chordomas typically present with pain, radicular symptoms or signs and symptoms of cord compression. On imaging, chordomas should be strongly considered when a destructive osseous lesion is identified in the sacrococcygeal region or skull base that contains a large soft tissue component that is very T2 hyperintense to marrow (Figure 5).

Skull Base Chordoma and Chondrosarcoma: Neuroradiologist’s …
2024年9月19日 · Skull base chordomas and chondrosarcomas are distinct types of rare, locally aggressive mesenchymal tumors that share key principles of imaging investigation and multidisciplinary care. Maximal safe surgical resection is the treatment choice for each, often via an expanded endoscopic endonasal approach, with or without multilayer skull base repair.
State-of-the-Art Imaging in Human Chordoma of the Skull Base
This article describes the radiologic characteristics of chordoma and differential diagnosis and gives an overview of evolving imaging studies and future perspectives in radiology of this tumour entity.
Chordoma Radiology: Insights and Imaging Guide
In this guide, we delve into various aspects of chordoma radiology, starting with an overview of chordoma and its manifestations. We then explore advanced imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT) scanning, and their specific applications in chordoma assessment.
Chordoma at the skull base, spine, and sacrum: A pictorial essay
Chordomas are rare tumors believed to be arising from the notochord remnant. They are usually found in the axial skeleton, including the clivus of the skull base, vertebral bodies of the mobile spine, and sacrococcygeal regions. Chordomas commonly affect adults in their age of 60s. However, they could also be present in any age group.
Chordomas of the skull-base are typically slow-growing, notochord-derived tumors that most commonly originate along the clivus. Skull base chordoma is treated with surgery and radiotherapy. Local recurrence approaches 50% at 10 years. Radiologists play a critical role in diagnosis, treatment planning, and follow-up.
