Prenatal diagnosis of achondrogenesis.

Abstract

An achondrogenic fetus, in whom the diagnosis was made prior to delivery by plain abdominal X-rays, is presented. The intrauterine characteristic roentgenographic manifestations are the short dense tubular bones of the extremities. An early diagnosis in fetuses with this disease can be made on a plain abdominal X-ray in the 22nd-24th week of gestation.
