[Selective Arterial Embolization for a Large Pelvic Aneurysmal Bone Cyst Treatment]

Area of Science:

• Orthopedics
• Musculoskeletal Oncology
• Interventional Radiology

Background:

• Aneurysmal bone cysts (ABCs) are benign musculoskeletal tumors often affecting young patients.
• Aggressive ABCs can be large, posing surgical challenges and requiring complex reconstructions.
• Standard treatments include curettage and bone grafting, with in-bloc resection for aggressive lesions.

Purpose of the Study:

• To present a case demonstrating the efficacy of selective arterial embolization for a large ABC.
• To highlight embolization as a viable treatment option for complex or aggressive ABCs.

Main Methods:

• Selective arterial embolization was employed as a primary or adjuvant treatment modality.
• The case involved a large aneurysmal bone cyst with a difficult surgical approach.

Main Results:

• Selective arterial embolization led to successful treatment of the large aneurysmal bone cyst.
• The intervention managed a case with complex surgical resolution requirements.

Conclusions:

• Selective arterial embolization is an effective treatment option for large and aggressive aneurysmal bone cysts.
• Embolization can be crucial in managing cases where surgical intervention is challenging or complex.
