Summary
Epidural cavernous angiomas are rare vascular malformations causing spinal cord compression. This study highlights two cases, emphasizing their MRI features and differential diagnosis for accurate identification.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Cavernous angiomas (or cavernomas) are vascular malformations that can occur anywhere in the neuraxis.
- Epidural locations are exceptionally rare, often overlooked in the differential diagnosis of spinal cord compression.
Observation:
- Two distinct cases of solitary epidural dorsal cavernous angiomas causing spinal cord compression are presented.
- The first case involved a purely epidural lesion without bone changes, while the second featured foraminal extension.
Findings:
- Both cases were histologically confirmed epidural cavernous angiomas.
- Magnetic resonance imaging (MRI) features are detailed, focusing on differentiating these lesions from other causes of spinal cord compression.
Implications:
- Recognizing the rare epidural cavernous angioma is crucial for accurate diagnosis of spinal cord compression.
- Understanding MRI characteristics aids in distinguishing these lesions, potentially improving patient management and outcomes.
