Extracranial presentation of craniocervical chordoma

|August 1, 1984
Summary
Chordomas are rare tumors originating from the notochord. This case highlights a craniocervical chordoma presenting unusually as a parotid mass, challenging initial diagnosis.
Area of Science:
- Oncology
- Neurosurgery
- Pathology
Background:
- Chordomas are rare, slow-growing tumors arising from notochordal remnants.
- They typically occur in the sacrum, spine, or skull base (craniocervical region).
- Craniocervical chordomas often manifest with neurological or ophthalmological symptoms.
Observation:
- A patient presented with a parotid mass initially misdiagnosed as a benign mixed tumor.
- Over 1.5 years, the mass progressed to an extensive intracranial tumor.
- The intracranial tumor was ultimately diagnosed as a chordoma.
Findings:
- This case represents an atypical presentation of a craniocervical chordoma.
- The initial presentation mimicked a benign parotid gland tumor, delaying definitive diagnosis.
- Diagnosis was complicated by the tumor's unusual location and initial misclassification.
Implications:
- Highlights the importance of considering rare tumors in differential diagnoses, even with atypical presentations.
- Emphasizes the challenges in diagnosing chordomas, particularly in the head and neck region.
- Underscores the need for thorough diagnostic workups for persistent or progressing masses.

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:26Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
