Summary
Primary osteogenic sarcoma of the skull is a rare condition. This case highlights the clinical presentation, imaging findings, and surgical management of a large skull osteosarcoma in a young adult.
Area of Science:
- Oncology
- Neurosurgery
- Radiology
Background:
- Primary osteogenic sarcoma of the skull is exceptionally rare, accounting for only 1-2% of all skull tumors.
- This malignancy typically presents as a rapidly growing mass.
Observation:
- A 21-year-old male presented with a large, 7-month-growing scalp mass causing headaches and tenderness.
- Imaging revealed a 12 cm x 7 cm highly vascularized mass, predominantly extracranial, supplied by the external carotid artery.
- Surgical intervention included embolization of feeding arteries followed by mass removal.
Findings:
- Histopathological analysis confirmed a high-grade osteoblastic osteosarcoma.
- The tumor was primarily extracranial (90%) with a small intracranial component (10%).
Implications:
- This case underscores the importance of comprehensive imaging and vascular assessment for skull osteosarcomas.
- Reviewing literature aids in understanding optimal diagnostic and therapeutic strategies for these rare tumors.
