Crouzon syndrome
Growth
Hormone Deficiency in a Case of Crouzon Syndrome with Hydrocephalus. The patient"s bone age was only 4. 5-5 years according to the Greulich and Pyle atlas.
Growth
Hormone Deficiency in a Case of Crouzon Syndrome with Hydrocephalus. MRI revealed obstructive hydrocephalus of both lateral ventricles, shallow orbits, and cerebellar tonsil herniation (Chiari I malformation). Pituitary height was 5.6 mm in midsagittal T1-weighted spin-echo MRI.
An inherited
FGFR2 mutation increased osteogenesis gene expression and result in Crouzon syndrome. Crouzon syndrome patients and morphology measurement of orbit. a Five-generation Crouzon syndrome pedigree. Affected individuals are indicated by filled symbols, the proband is marked with an upward arrow. b Facial photographs of the Crouzon syndrome patients. c Morphology measurement of orbit.

Affected individuals are indicated by filled symbols and the proband is marked with an arrow. b, c Computed tomography and magnetic resonance imaging did not reveal retrobulbar hematoma and revealed shallow orbits and obvious ocular proptosis in the proband. d Facial photographs of patients with Crouzon syndrome

Crouzon
syndrome complicated with binocular strabismus and extraocular muscle fibrosis: a case report. CT scans of the head and a three-dimensional reconstruction of head showing the narrow and elongated shape of the patient’s cranium. The superior region of the forehead appeared pointed and there was a partial upward projection of the skull. The cranial sutures were fused and the overall shape of the head resembled that of a boat
Crouzon
syndrome complicated with binocular strabismus and extraocular muscle fibrosis: a case report. CT scans of the orbits and a three-dimensional reconstruction of the orbits showing shallowed orbits, prominent eyeballs, and slight medial shifts in recti muscles within both eyes
Crouzon syndrome is rare disorder characterized by premature craniosynostoses.
Pathology
Features include:
- abnormal calvarial shape: in severe case can give a "cloverleaf skull"
- shallow orbits with exophthalmos
- mid facial hypoplasia
- bifid uvula
Genetics
It carries an autosomal dominant inheritance due to a mutation in fibroblast growth factor receptor 2 (FGFR2) gene on chromosome 10q25-26.
Associations
- Chiari I malformations : may be present in ~70% of cases
- hydrocephalus
- stylohyoid ligament calcification: may be present in ~50% of patients over 4 years old
- cervical spine abnormalities
- cervical spine fusion
- elbow malformations
- hand deformities
- agenesis of corpus callosum
History and etymology
It is named after L E Octave Crouzon, French physician who first described the condition in 1912 .
