Meningioma - Solitary - Temporal

A 75 year-old woman presented with a change in personality, memory loss, headaches and a mild left hemiparesis.

Note the Isointense Tumor on T1              Show the Gadolinium Enhancement              Note that the Tumor is Arising from the Dura

Meningioma (Temporal). (Left ) T1-weighted axial MRI; (Middle) T1-weighted with gadolinium axial MRI; (Right) T1-weighted with gadolinium coronal MRI. Note the large, well demarcated mass. The tumor is dural based and compresses the adjacent temporal lobe. The mass is isointense on T1-weighted images but strongly enhances with contrast. This is the typical appearance of a meningioma.

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)
● Tentorial
● Convexity
● Subfrontal
● Cerebellopontine angle
● Sphenoid wing
● Foramen magnum
● Optic nerve
