5. What location is most severely affected in patients with meningiomas?

Explanation

Meningiomas are tumors that occur in the meninges, the protective membranes surrounding the brain and spinal cord. The falx cerebri is a fold of the dura mater that separates the two cerebral hemispheres. It runs along the midline of the brain. When meningiomas develop in the falx regions, they can cause severe effects due to their location and potential compression of brain tissue. Therefore, the falx regions are the most severely affected location in patients with meningiomas.

6. What is histologically representative of meningiomas?

Explanation

Whirls are histologically representative of meningiomas. Meningiomas are typically characterized by the presence of whorls, which are concentric arrangements of tumor cells. These whorls can be seen under a microscope and are a key feature used to diagnose meningiomas. Other histological features commonly associated with meningiomas include hypercellularities, rosettes, and swirls. However, the presence of whirls is the most specific and characteristic feature of meningiomas.

Ependymomas are tumors that arise from the ependymal cells lining the central canal of the spinal cord. They are typically slow-growing and can cause symptoms such as back pain, weakness, and sensory changes.
