Aneurysmal bone cyst of the zygomatic arch

Area of Science:

• Head and Neck Surgery
• Vascular Lesions
• Surgical Oncology

Background:

• Aneurysmal bone cysts (ABCs) are uncommon vascular lesions, typically affecting long bones.
• ABCs of the head and neck are exceptionally rare, with only two prior reports involving the zygoma.
• This case represents a novel occurrence of an ABC in the zygomatic arch.

Observation:

• A patient presented with an aneurysmal bone cyst originating in the zygomatic arch.
• The cyst exhibited significant intracranial extension, posing a complex surgical challenge.
• An intratemporal fossa approach was utilized for surgical access.

Findings:

• The treatment involved a two-stage approach: selective arterial embolization followed by complete excision.
• This combined therapeutic strategy effectively managed the aneurysmal bone cyst.
• The surgical outcome was successful, with complete resection achieved.

Implications:

• This case highlights the successful management of a rare zygomatic arch aneurysmal bone cyst with intracranial extension.
• Selective arterial embolization combined with complete surgical resection is a viable and safe treatment option for selected ABC cases.
• The intratemporal fossa approach provides effective access for managing complex zygomatic arch lesions.
