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.
