Cloverleaf skull

The stenotic sutures are shown in blue. An extreme form of pansynostosis, skull growth occurs laterally, via the patent squamosal sutures (red arrows). Growth upward or forward in the midline through a length of suture or bony defect causes a focal bulge (green arrows). The 3 protrusions resemble a 3-leaf clover. (Contributed by Dr. Sherman Stein.)
