Q:
What is superior sagittal sinus meningioma?
A:
The superior sagittal sinus is an unpaired area along the attached margin of the falx cerebri. It allows blood to drain from the lateral aspects of anterior cerebral hemispheres to the confluence of sinuses. Meningioma is typically a slow-growing tumor that forms from the meninges.
Causes
The causes of meningiomas are various. Most cases are sporadic, appearing randomly, while some are familial. Persons who have undergone radiation, especially to the scalp, are more at risk for developing meningiomas, as are those who have had a brain injury.
Symptoms
- Focal seizures
- Progressive spastic weakness
- Increased intracranial pressure
- Diplopia (Double vision) or uneven pupil size
Prevention
Maintaining a normal body weight and avoiding unnecessary dental x-rays can reduce the risk of superior sagittal sinus meningioma.
Treatment
- Observation
- Surgery
- Radiation therapy
- Chemotherapy
