Subependymal giant cell astrocytoma (SEGA, SGCA, or SGCT) is a low-grade astrocytic brain tumor (astrocytoma) that arises within the ventricles of the brain. [1] It is most commonly associated with tuberous sclerosis complex (TSC) .

Sep 29, 2024 · Subependymal giant cell astrocytomas (SGCAs or alternatively SEGAs) are benign tumors (WHO grade 1), seen almost exclusively in young patients with tuberous sclerosis. They can be either asymptomatic or symptomatic due to obstructive hydrocephalus; surgical treatment is often curative.

What is Subependymal Giant Cell Astrocytoma? Subependymal giant cell astrocytoma (SEGA) is a tumor that arises in the ventricular system of people with tuberous sclerosis, a rare genetic disease that causes benign tumor growth throughout the body.

Subependymal giant cell astrocytoma is a rare, benign brain tumor that arises from astrocytes, the supportive cells in the nervous system.

Subependymal giant cell astrocytoma (SEGA) is a rare benign tumor of astrocytic origin characterized by poor growth [1]. This tumor is included among first-degree brain tumors, according to the World Health Organization (WHO) [2] …

In this study, we reviewed the clinical characteristics of five cases of subependymal giant cell astrocytoma (SEGA) at our hospital between May 1997 and July 2012. The median age was 18 years old (range, 8 to 26).

Subependymal giant cell astrocytomas are characteristic brain tumors that occur in 10% to 20% of tuberous sclerosis complex patients and are almost exclusively related to tuberous sclerosis complex.

Oct 7, 2024 · Subependymal giant cell astrocytoma (SEGA) is most often found in patients with TSC (Tuberous Sclerosis Complex). Although it has been classified as a benign tumor, it may create a serious medical problem leading to grave consequences, including young patient demise.

Subependymal giant cell astrocytoma is a slow-growing tumor that usually arises in the wall of the lateral ventricles during the first 2 decades of life. It is seen in 5% to 15% of patients with confirmed tuberous sclerosis, a genetic disease caused by mutations in the TSC1 or TSC2 genes.

Subependymal giant cell astrocytoma (SEGA) is a type of brain tumour that develops in 10-15% of individuals with tuberous sclerosis complex (TSC). SEGAs can be unilateral or bilateral, developing from benign subependymal nodules (hamartomas) located near the foramen of Monro.
