Abstract
We report a case of fetal pericallosal lipoma occurring at the anterior interhemispheric
fissure and associated with agenesis of the corpus callosum. During targeted
prenatal ultrasonography at 26 weeks’ gestation, the lesion was seen as a
highly echogenic mass. MR imaging performed at 35 weeks’ gestation and during
the postnatal period revealed a pericallosal fatty mass and agenesis of the corpus
callosum.
