Midline nevus of Jadassohn (CT)

Axial CT scan of a 3-year-old girl with a midline nevus of Jadassohn involving the forehead and nasal bridge (not shown). Agenesis of the corpus callosum and right hemimegalencephaly are demonstrated; the right occipital horn shows mild colpocephaly. The straightening of the right frontal horn is a feature of hemimegalencephaly. (Contributed by Dr. Laura Flores-Sarnat.)
