title: Congenital subependymal giant-cell astrocytoma: case report with prenatal ultrasonogram.
abstract: BACKGROUND
  A prenatal sonogram at 27 weeks of gestation revealed a brain mass along the frontal horn and body of the lateral ventricle near the foramen of Monro in the fetus.
  
  
  METHODS
  A huge subependymal giant-cell astrocytoma was nearly totally resected at 11 days of age.
  
  
  RESULTS
  There was no syndromic family history, but features substantiating the diagnosis of tuberous sclerosis were recognized at 4 years of age.
  
  
  CONCLUSIONS
  The sonographic finding of a tumor in the region of the foramen of Monro should raise the suspicion of a subependymal giant-cell astrocytoma, a tumor characteristically associated with tuberous sclerosis.
