Aneurysmal bone cyst of the ethmoid
Head & Neck Surgery
|November 1, 1982
Summary
This is the first reported case of an extragnathic, facial aneurysmal bone cyst involving the ethmoid bone. The rare condition presented as periorbital swelling and nasal mass in a pregnant woman.
Area of Science:
- Otorhinolaryngology
- Head and Neck Surgery
- Radiology
Background:
- Aneurysmal bone cysts (ABCs) are rare, benign, expansile bone lesions.
- Facial bone involvement is uncommon, with most cases reported in the jaws.
Observation:
- A 20-year-old pregnant woman presented with a 5-month history of left periorbital swelling, nasal mass, nasal obstruction, blurred vision, and diplopia.
- Imaging studies including sinus series, facial lamiograms, and EMI (CT) scan were performed.
- Needle aspirates from the intranasal mass yielded dark, bloody fluid.
Findings:
- The case is the first reported instance of an extragnathic, facial aneurysmal bone cyst involving the ethmoid sinus.
- Pathologic findings confirmed the diagnosis of aneurysmal bone cyst.
Implications:
- This case highlights the importance of considering rare diagnoses in the differential for facial masses, even in unusual locations.
- Early diagnosis and surgical intervention are crucial for managing symptoms and preventing complications.
- Further research into the etiology and management of extragnathic ABCs is warranted.
