Summary
This study presents a rare case of low-grade chondrosarcoma in the skull base, initially presenting as headache and abducens nerve paralysis. Magnetic resonance imaging (MRI) proved crucial for diagnosis, distinguishing it from other skull base tumors.
Area of Science:
- Neuro-oncology
- Radiology
- Skull Base Surgery
Background:
- Skull base tumors present diagnostic challenges, often mimicking other pathologies.
- Early and accurate diagnosis is crucial for effective treatment and patient outcomes.
Observation:
- A 24-year-old female presented with headache and right abducens nerve paralysis.
- Imaging revealed a ring-enhancing mass behind the right posterior clinoid process.
- MRI demonstrated characteristic signal intensities and enhancement patterns suggestive of chondrosarcoma.
Findings:
- Histopathological examination confirmed a low-grade chondrosarcoma.
- The tumor was successfully resected via an orbitozygomatic infratemporal approach.
- No adjuvant radiation or chemotherapy was required post-operatively.
Implications:
- Magnetic resonance imaging (MRI) is the most valuable diagnostic tool for differentiating chondrosarcoma from other skull base tumors.
- Surgical resection through tailored approaches can achieve good outcomes for low-grade chondrosarcomas.
- This case highlights the importance of advanced imaging in diagnosing rare skull base neoplasms.
