Summary
Aneurysmal bone cysts are rare benign tumors. This case highlights a frontal sinus aneurysmal bone cyst in a child, successfully treated with surgical excision and reconstruction.
Area of Science:
- Oncology
- Pediatric Surgery
- Head and Neck Surgery
Background:
- Aneurysmal bone cysts (ABCs) are benign, vascular, cystic osseous tumors.
- While uncommon in the head and neck (2% of cases), the mandible is the most frequent site.
- Frontal sinus involvement is exceptionally rare, particularly in pediatric populations.
Observation:
- A pediatric patient presented with an aneurysmal bone cyst originating in the frontal sinus.
- Radiographic studies aided in the diagnostic process.
- The diagnosis was pathologically confirmed following surgical excision.
Findings:
- Complete en-bloc excision of the frontal sinus aneurysmal bone cyst was achieved.
- A bifrontal craniotomy approach facilitated the tumor removal.
- The resulting cranial defect was immediately reconstructed using a split calvarial bone graft.
Implications:
- This case expands the known anatomical distribution of aneurysmal bone cysts.
- It underscores the importance of considering rare diagnoses in pediatric head and neck masses.
- Successful surgical management demonstrates the feasibility of complete resection and reconstruction for these lesions.
