Name of the Patient : Abc Xyzb Shlmn / M / 1 yr.
Referred by : Dr. Abc Xyzwant.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O a small swelling at the root of the nose since birth.

EXAMINATION :

M.R.I of the brain was performed using the following parameters :

5 mm thick T1 Weighted, proton and T2 Weighted axial images.
3 mm thick STIR coronal images.
5 mm thick T1 Weighted sagittal images.

SOME IMAGES SHOW PATIENT MOTION INSPITE OF SEDATION.

OBSERVATION :

There is a fairly well-defined space-occupying lesion which is near isointense to CSF on all the pulse sequences in the region of the nasal cavity/ethmoidal air cells on the right side. The neck of this lesion is seen to communicate with the CSF space in the frontal regions via a defect in the floor of the cribriform plate of the ethmoid bone.

There is no focal area of altered signal intensity within the brain parenchyma.

Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.

IMPRESSION :

The MRI features are suggestive of a fronto-ethmoidal cephalocele (meningocele) as described.
