Craniodiaphyseal dysplasia Classification and external resources
OMIM	218300

Craniodiaphyseal dysplasia (also known as CDD or lionitis) is an extremely rare autosomal recessive bone disorder that causes calcium to build up in the skull, disfiguring the facial features and reducing life expectancy.

These calcium deposits decrease the size of cranial foramina, and can also decrease the hole in the cervical spinal canal. In the few cases recorded, most of the sufferers died in childhood.

The underlying genetics are uncertain.^[1]

[edit] Diagnosis

Among the medical signs are dacryocystitis, seizures, mental retardation, and paralysis, each of which is a complication resulting from the diminutive foramina. A common sign reported as a result of the disease has been an indifference of the size of the eyes, having one usually bigger in size then the other.

[edit] Depiction

Peter Bogdanovich's 1985 film Mask drew public attention to the case of Roy L. "Rocky" Dennis, an American boy who died of the disorder in 1978.

In the American medical television series comedy-drama Grey's Anatomy episode "Yesterday", a teenage boy is depicted with lionitis.[1]

The main character of the two-issue comic book miniseries Friday the 13th: How I Spent My Summer Vacation by Wildstorm is a 13-year old boy suffering from the disorder (with its effects and name being stated).
