Summary
This study identifies key imaging features distinguishing benign vertebral collapse (VC) from malignancy. Recognizing these signs on CT and MR scans can prevent misdiagnosis and unnecessary biopsies for painful vertebral collapse.
Area of Science:
- Radiology
- Oncology
- Orthopedics
Background:
- Vertebral collapse (VC) can present with imaging features mimicking malignancy.
- Distinguishing benign from malignant causes of VC is crucial for appropriate patient management.
Purpose of the Study:
- To describe the characteristic imaging findings of benign non-traumatic vertebral collapse that can be mistaken for malignancy.
- To aid in the differentiation of benign VC from malignant lesions using computed tomography (CT) and magnetic resonance (MR) imaging.
Main Methods:
- Retrospective review of 15 cases of benign vertebral collapse with malignancy-like features.
- Analysis of radiographic, CT, and MR imaging findings.
- Correlation with percutaneous biopsy and 12-month follow-up.
Main Results:
- Malignancy-mimicking features included anterolateral/posterior cortical destruction, pedicle involvement, epidural masses, and diffuse low T1 signal intensity.
- Benign indicators were intravertebral vacuum phenomenon, fracture lines within the vertebral body/pedicles, and high T2 signal intensity.
Conclusions:
- Benign non-traumatic osteolytic vertebral collapse can radiographically simulate malignancy.
- Specific CT and MR imaging features are valuable in diagnosing benign VC, potentially avoiding repeat biopsies.
