Summary
Spinal intramedullary cavernomas predominantly affect women, often presenting with acute symptoms like pain and sensorimotor deficits. Preoperative status is key for outcomes, and surgery isn't always the first option.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Malformations
Background:
- Spinal intramedullary cavernomas are rare vascular malformations.
- Review of 57 literature cases and one personal case provides insights into their characteristics.
Observation:
- Affects women predominantly (70%), with peak onset in the third and fourth decades.
- Cervical and thoracic lesions are equally represented, typically small (1.7 cm) and stable.
- Acute symptoms (pain, sensorimotor deficits) are common, mimicking multiple sclerosis.
- Bleeding occurs in 60% of women, with cervical lesions having higher bleeding frequency and shorter clinical course.
- Magnetic resonance imaging is diagnostic; angiography is negative.
Findings:
- Preoperative status is the most critical factor for patient outcomes.
- Sex, age, size, location, duration of symptoms, and extent of surgical removal do not significantly impact outcomes.
- Repeated bleeding cycles are common if not recognized, with a mean interval of 39.6 months.
Implications:
- Non-surgical management may be considered, as recovery from initial bleeding is frequent.
- Early recognition and management are crucial, especially for cervical lesions.
- Understanding risk factors and prognostic indicators aids in clinical decision-making for spinal cavernomas.
