Hypochondroplasia: Radiological Diagnosis and Differential Diagnosis
Hypochondroplasia (H.) has been considered for a long time a mild form of achondroplasia (A.). Both entities, on the contrary, are definitely two separate conditions, hypochondroplastic parents having never had children with A. and vice versa. H. however may exhibit clinical and radiographic variations, so that in a severe form, it may resemble A. H. is not a rare hereditary chondrodystrophy, although relatively few cases have been reported in the literature. This probably depends on the numerous though mild clinical and radiological features, which suffer from a lack of specificity and are also seen in other types of disproportionate dwarfism.
