Summary
This review of clival chordomas highlights computed tomography (CT) and magnetic resonance imaging (MRI) for diagnosis. MRI offers superior soft tissue visualization, aiding treatment planning for these rare tumors.
Area of Science:
- Neurosurgery
- Oncology
- Radiology
Background:
- Clival chordomas are rare bone tumors originating from the skull base.
- Reviewing three cases provides insights into their presentation and diagnostic imaging.
- Understanding imaging characteristics is crucial for effective management.
Observation:
- Case 1: Tumor invasion into the upper cervical canal and paravertebral planes.
- Case 2: A rare occurrence in a 12-year-old pre-adolescent.
- Case 3: Petro-clival erosion with a significant nasopharyngeal component.
Findings:
- Computed tomography (CT) excels at showing bone destruction, sequestra, and calcification.
- Magnetic resonance imaging (MRI) is superior for delineating soft tissue extent and aiding treatment planning.
- Vertebral angiography reveals tumor vascularity through displacement, encasement, and blush, with embolization proving beneficial pre-operatively.
Implications:
- Accurate imaging is vital for surgical planning and treatment of clival chordomas.
- MRI's multiplanar capabilities enhance understanding of tumor extent.
- Multimodal imaging approaches, including angiography and embolization, can improve outcomes for these challenging tumors.
