Summary
Arteriovenous malformation (AVM) in the masseter muscle is rare. This case report details a successful embolization and surgical excision of a masseter muscle AVM, offering insights into diagnosis and treatment.
Area of Science:
- Vascular Surgery
- Head and Neck Oncology
- Radiology
Background:
- Arteriovenous malformations (AVMs) are rare vascular tumors characterized by abnormal direct connections between arteries and veins.
- Intracranial AVMs are common, but intramuscular AVMs in the head and neck are infrequent, with masseter muscle involvement being the most prevalent site.
Observation:
- A 36-year-old patient presented with a 1.5-year history of progressive right cheek pain and a growing mass.
- Diagnostic evaluation confirmed an arteriovenous malformation within the masseter muscle.
Findings:
- The patient underwent successful preoperative embolization followed by complete surgical excision of the masseter muscle AVM.
- This case highlights the diagnostic and therapeutic approaches for this rare condition.
Implications:
- Early diagnosis and appropriate management, including embolization and surgical resection, are crucial for treating masseter muscle AVMs.
- This case contributes to understanding the clinical presentation and successful treatment strategies for rare head and neck vascular tumors.
