Case Report



Congenital Subependymal giant cell astrocytoma (SEGA), diagnosed in fetal and neonatal period, is extremely rare. Previous studies have reported poor surgical outcomes of this small group of patients. We encountered a patient diagnosed as congenital SEGA and report the surgical outcome along with interesting immuno-phenotypes of giant tumor cells.


Ventriculomegaly and a hypoechoic mass near the foramen of Monro were detected in a fetus on prenatal ultrasonography in the 35th week of gestation. Surgery was scheduled 2 months later to reduce the risk of operative complications. At postnatal 2 months, gross total resection of the tumor was achieved without complications. The patient had been followed up for 1 year without tumor recurrence. In double immunofluorescence, the prototype cells of SEGA expressed a variety of neural stem cell (nestin and Sox2) and radial glial cell markers (vimentin and brain lipid-binding protein), in addition to glutamate/aspartate transporter and glial fibrillary acidic protein.


Congenital SEGA can be successfully treated with judicious use of observation period and careful evaluation of general conditions. Pathological findings support the concept that SEGA may originate from aberrant radial glial cells in the developing brain.
