We conclude that (a) hypoplasia of the cerebellar vermis, especially the anterior vermis, is often associated with a complex brainstem malformation; (b) the latter comprises a "molar tooth" brainstem and vermis hypoplasia-dysplasia malformation complex; (c) this complex may include the Dandy-Walker malformation, occipital cephalocele, and some abnormalities of the cerebrum as evidenced by frequent mental retardation; and (d) the "molar tooth" sign or malformation is causally heterogeneous as it occurs in several distinct malformation syndromes including Joubert syndrome, Arima syndrome, Senior-Loken syndrome, COACH syndrome, and probably familial juvenile nephronophthisis.
