Sonographic images of thanatophoric dysplasia. A: Femur (16 weeks gestation) in thanatophoric type 2 (TD 2) is straight and very short with metaphyseal spikes. B: Femur (20 weeks gestation) in thanatophoric type I (TD1) is curved with metaphyseal flaring. C,D: Two dimensional sonogram of a fetus with thanatophoric type I (TD1) (18 weeks gestation) with a tall/high metopic ridge, almost absent nasal bone (D), and facial disproportion since the metopic suture and mandible are not in the same plane, suggesting coronal synostosis. E: Three dimensional sonographic image of TD1 at 24 weeks showing a flattened nasal bridge and brachydactyly.
