Computed tomography findings of Crouzon syndrome: A case report

Crouzon syndrome is a genetic condition characterized by a premature fusion of skull sutures resulting in head and facial deformities. Crouzon syndrome is usually suspected at birth through physical examination or in the antenatal period via ultrasonographic assessment. Once Crouzon syndrome is suspected, advanced imaging methods such as three-dimensional computed tomography must be requested, showing early signs of cranial sutures fusion. In this paper, we present a case of a six-year-old girl who was taken to a pediatrician control appointment due to abnormal facies. During the physical examination, a suspicion of Crouzon syndrome was raised. Therefore, a head computed tomography was requested, showing asymmetrical calvarium thickening, diffuse indentation of the inner table of the skull, and moderate hydrocephalus with a big cyst in the posterior fossa. Due to these findings, the patient was remitted to maxillofacial surgery for further evaluation; however, the medical appointment could not be achieved as a consequence of the poor medical insurance of the girl. This paper aims to describe and discuss the computed tomography findings of Crouzon syndrome.
