Weismann-Netter-Stuhl syndrome: toxopachyostéose diaphysaire tibio-péronière.

Three cases of Weismann-Netter-Stuhl syndrome in nonrelated patients are reported. The classic feature of the syndrome is a congenital anterior bowing of the middiaphyseal part of both tibiae and fibulae. The authors' experience and review of 37 cases reported since its original description in 1954 has revealed a definite association of diaphyseal bowing of other long bones and squaring of the pelvis. The association of mental retardation, goiter, and anemia previously described are felt to be coincidental. At present, this syndrome seems to be some sort of diaphyseal dysplasia, which may be familial or sporadic. The radiographic findings are quite specific and allow easy differentiation of this entity from other disease states: knowledge of this syndrome by the radiologist should prevent unnecessary diagnostic evaluation by the clinician.
