Abstract. Case Management Examples – Xian-Lun Zhu, M.D. You H(1), Kim YI, Im SY, Suh-Kim H, Paek SH, Park SH, Kim DG, Jung HW. Nearly all arise in the setting of the tuberous sclerosis complex (TSC). Methods: Sixty-four subependymal giant cell astrocytoma surgeries in 57 tuberous sclerosis complex patients with at least a 12-month follow-up were included in the study. Focused Subependymal Giant Cell Astrocytoma with stained slides of pathology. Tips for Managing Pineal Region Tumors in Children – Tad Tomita, M.D. We have previously reported on Technique for Resecting a Supratentorial Anaplastic Astrocytoma in a Child – by John Myseros, M.D. Subependymal giant cell astrocytoma associated with tuberous sclerosis presenting with intratumoral bleeding. Objective: The exact cell of origin of subependymal giant cell astrocytoma is debated but most currently consider the tumor in the astrocytic category. Subependymal giant cell astrocytoma (SEGA, SGCA, or SGCT) is a low-grade astrocytic brain tumor (astrocytoma) that arises within the ventricles of the brain. Subependymal giant cell astrocytoma (SEGA) is a benign, slowly growing tumor typically occurring in the setting of tuberous sclerosis complex (TSC). You can search for trials based on the type of cancer, the age … These giant cells (also known as balloon cells) are the neuropathological hallmarks of SEGA.

Individuals with very slow growing tumors where complete surgical removal by stereotactic surgery is possible may experience total remission. However, it may be misinterpreted as other high-grade brain tumors due to the presence of large tumor cells with conspicuous pleomorphism and occasional atypical features, such as tumor necrosis and endothelial proliferation. The histogenesis of SEGA is controversial and its astrocytic nature has been doubted. TSC is an autosomal dominantly in-herited neurocutaneous syndrome that affects any organ sys-tem of the body.
