Aneurysmal bone cyst of the skull. Case report

Area of Science:

• Neurosurgery
• Skeletal Pathology
• Oncology

Background:

• Aneurysmal bone cysts (ABCs) are rare, benign, expansile bone lesions. While uncommon in the calvaria, they can occur and pose unique surgical challenges.
• Frontal bone lesions require careful management due to proximity to intracranial structures and the potential for cosmetic and functional deficits.

Observation:

• Presentation of a rare case of an aneurysmal bone cyst specifically located in the frontal bone.
• The lesion, though benign, demonstrated potential for intracranial extension, highlighting the need for thorough evaluation.

Findings:

• Surgical removal is the recommended treatment for frontal bone aneurysmal bone cysts, aiming for complete excision.
• Surgical intervention in the calvaria is often more straightforward than in other locations like the spine or long bones, allowing for total removal.
• Aneurysmal bone cysts are a distinct and recognizable pathological entity with an excellent prognosis following complete resection.

Implications:

• Complete surgical excision of frontal bone aneurysmal bone cysts leads to a definitive cure and excellent patient outcomes.
• Early diagnosis and surgical management are crucial to prevent potential intracranial complications and ensure optimal functional and cosmetic results.
• This case underscores the importance of considering aneurysmal bone cysts in the differential diagnosis of frontal bone lesions.
