![This 6-year-old girl had a growing but asymptomatic tumor. (A) Her screening magnetic resonance imaging at age 2 revealed a subependymal giant cell astrocytoma with mild enlargement of the right lateral ventricle. (B) By age 6 years, the lesion had enlarged markedly.[4]](/images/7/7f/Subependymal_giant_cell_astrocytoma_MRI_2.jpg)
