A 52 year-old woman presented with headaches, vertigo and falling. |
| Meningioma (Clivus). (Left)
T1-weighted axial MRI; (Right) T1-weighted with gadolinium axial
MRI. Note the well demarcated mass that enhances with gadolinium,
and nearly obliterates the foramen magnum. Surgical resection
demonstrated a meningioma arising from the clivus. Many of the
patient's symptoms resulted from obstructive hydrocephalus. Meningiomas are common tumors that arise from the meninges and can occur within the spinal canal as well as intracranially. They are typically benign histologically, and can be surgically resected if they are in an accessible location. They are more common in women than men, and account for approximately 20% of all primary brain tumors. Similar to low grade gliomas, they grow very slowly. They may result in seizures, focal neurological signs, or both, depending on their location. Some of the more common locations for meningiomas include: ● Parasagittal (attached to the falx) |
