ABSTRACT

Diagnosis: 1) Fronto-nasal encephalocele 2) Colpocephaly

History: 2 day old female infant with midline mass above the nose.

Findings: T1 sagital view showing enlarged posterior lateral ventricles. The image shows a midline opening of the skull above the bridge of the nose with protrusion of brain parenchyma through the skull defect. T2 axial views show bilateral asymmetrically enlarged lateral ventricles (right>left). Brain parenchyma protruding from a midline skull defect at the level of the eyes with CSF communication into the mass. Parenchymal volume loss noted in parietal, occipital and frontal lobes.

Ddx: Encephalocele Meningocele Glioma Hemangioma Nasal Dermoid

Dxhow: MRI - protrusion of brain parenchyma and CSF through a midline skull defect is pathognomonic for encephalocele.

Exam: Soft midline mass noted above the patient's nose.

No MeSH data available.


T1 sagittal view showing increased volume of the lateral ventricle and a mass protruding from a midline skull defect at the level of the eyes.  There is a region of decreased intensity within the mass consistent with CSF.  The location and intensity of the mass is consistent with a protrusion of brain parenchyma through the skull defect.  Parenchymal volume loss noted in occipital lobe.
