Synopsis
Cephalocele is a malformation caused by intracranial structures herniating through an opening in the skull. Encephaloceles specifically contain both meninges and brain, while meningoceles contain meninges and cerebrospinal fluid (CSF).
When the neural tube does not close properly during development, this can result in an encephalocele.
Cephaloceles are quite rare but can occur more frequently in patients with a family history of cephaloceles.
Encephaloceles frequently occur as soft nodules or masses that grow as the infant grows and grow acutely with crying or during a Valsalva maneuver. The most common locations for encephaloceles are the occiput and the vertex located near the midline of the skull. However, encephaloceles have been reported near the nasal glabella and near the pharyngeal region.
Encephaloceles commonly lead to early deformities and can be mistaken for deeply seated hemangiomas or vascular malformations. The deformity can lead to the misperception of hypertelorism as well.
Repetitive cephaloceles in families may be attributed to specific genes responsible for controlling individual closure sites. Patients may report a history of meningitis.
