Summary
Spinal epidural cavernous hemangiomas are rare vascular tumors. Characteristic MRI findings include lobulated masses with high T2 signal intensity and strong enhancement, often causing bony erosion.
Area of Science:
- Neurology
- Radiology
- Oncology
Background:
- Spinal epidural cavernous hemangiomas are uncommon vascular tumors.
- Distinct from vertebral body cavernous hemangiomas, their epidural location is rare.
Purpose of the Study:
- To describe the radiologic findings of spinal epidural cavernous hemangiomas.
- Focus on magnetic resonance (MR) imaging characteristics.
Main Methods:
- Retrospective review of five pathologically proven cases.
- Evaluation of MR imaging (n=5) and CT scans (n=1).
Main Results:
- Lesions were thoracic (n=4) or lumbosacral (n=1), located in the epidural space with paravertebral extension.
- Observed were lobulated contours, partial spinal cord encirclement, high T2 signal intensity, and homogeneous enhancement.
- Common findings included adjacent bony erosion (n=5) and neural foraminal widening (n=4).
Conclusions:
- Spinal epidural cavernous hemangiomas exhibit distinct MR imaging features.
- Key findings include lobulated epidural masses, partial spinal cord encirclement, high T2 signal, and strong homogeneous enhancement.
