What is the difference between ependymoma and Subependymoma?

What is the difference between ependymoma and Subependymoma?

Although both ependymomas and subependymomas are iso/ hypointense on T1 sequences and hyperintense on T2 relative to brain parenchyma, the major difference is that ependymomas exhibit heterogeneous patterns of enhancement, whereas subependymomas do not enhance at all [18].

What is a subependymal lesion?

Subependymal hamartomas are small irregular nodules, measuring <1 cm, with their long axis perpendicular to the ventricular surface. They grow in proportion to the surrounding tissues and may calcify with increasing age.

Is Grade 2 ependymoma malignant in adults?

Grade II ependymomas are low grade tumors and can occur in either the brain or the spine. Grade III ependymomas are malignant (cancerous). This means they are fast-growing tumors.

What type of cancer is an ependymoma?

Ependymoma is a primary CNS tumor. This means that it starts in the brain or spinal cord rather than starting somewhere else in the body and spreading to the brain. Ependymoma is a kind of glioma. This means it starts in support cells (glial cells) of the brain.

What are subependymal nodules?

Subependymal nodules (SEN) are small accumulations of cells that are located on the walls of the cerebral ventricles (the spaces in the brain that contain cerebrospinal fluid (CSF). The nodules often accumulate calcium, and are then easily identified on MRI imaging of the brain.

How rare is an ependymoma?

In the United States, 200 new cases of ependymoma are found in children and adults each year. Ependymoma occurs more often in children than in adults. Ependymoma is the third most common type of brain tumors in children.

Can you die from ependymoma?

Taken together, these data confirm that approximately half of all children diagnosed with ependymoma died of their disease by 10 years after diagnosis.

Can ependymoma be cured?

All grades of ependymoma tumors are considered cancer. Like other primary brain and spinal cord tumors, these cancers are different in that they tend not to spread to other parts of the body, but can recur and require treatment. As with other cancers – some can be cured but others cannot.

Is ganglioglioma curable?

Low-grade gangliogliomas can be cured surgically, and complete tumor resection is the most effective treatment. Radiotherapy is reserved for progressive or malignant tumors after surgical treatment [9,10,11]. Here, we investigated the long-term clinical outcomes of 16 patients with ganglioglioma.
