FIG 1. Tubulo-nodular type of pericallosal lipoma. In utero and postnatal follow-up images (case 3).
A, Sonogram obtained in utero at 35 weeks' gestation. A biparietal image is shown. A hyperechoic mass (M) can be seen within the anterior midline. The lipoma appears slightly less echogenic than the parietal bone; its margins are irregular. The mass is extending toward the frontal lobes (arrows).
B, MR image obtained at birth. Sagittal view turbo spin-echo T1-weighted image (350/16/1) confirms the presence of the lipoma and the agenesis of the corpus callosum.
C, MR image obtained at birth. Frontal view turbo spin-echo T1-weighted image (350/16/1) shows the lateral extend of the lipoma.
D, MR image obtained at age 3 years. Mid-sagittal view turbo spin-echo T1-weighted sequence (450/15/1) shows the growth of the lipoma.
E, MR image obtained at age 3 years. Similar findings are revealed by the frontal view turbo spin-echo T1-weighted sequence (450/15/1).
