Summary
Aneurysmal bone cysts (ABCs) are rare, benign bone lesions. This report details the first-ever case of an ABC in the odontoid process, found in a 74-year-old patient experiencing pain and myelopathy.
Area of Science:
- Orthopedics
- Neurosurgery
- Pathology
Background:
- Aneurysmal bone cysts (ABCs) are uncommon, benign bone lesions typically affecting individuals under 20.
- The majority of ABCs occur in long bones (50%) and the vertebral column (20%).
Observation:
- A case of an aneurysmal bone cyst (ABC) was identified in the odontoid process.
- The affected patient was a 74-year-old individual presenting with pain and myelopathy.
Findings:
- This represents the first documented instance of an aneurysmal bone cyst (ABC) specifically located in the odontoid process.
- The lesion's presence in an elderly patient and its specific location are noteworthy.
Implications:
- This case expands the known anatomical distribution of aneurysmal bone cysts (ABCs).
- It highlights the importance of considering ABCs in the differential diagnosis of spinal lesions, even in older populations.
- Further research may be warranted to understand the pathogenesis and clinical behavior of ABCs in atypical locations.
