Name of the Patient : Abc Xyzhal Chaudlmn / M / 5 months.
Referred by : Dr. Abc Xyztal.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O nasal encephalocele since the age of 4 months.
M.R.I of the brain was performed using the following parameters :
4 mm thick T1 Weighted, proton and T2 Weighted axial images.
3 mm thick T1 Weighted coronal images.
MR cisternogram in the coronal and sagittal planes.
There is seen a fairly large, well-defined approximately 2.1 x 4.2 x 2.3 cms sized mass lesion in the right nasal cavity, extending out through the right nostril. This lesion nearly follows CSF signal on all the pulse sequences. There is resultant deviation of the nasal septum to the left with significant obstruction of the left nasal cavity.
There is no herniation of the brain parenchyma into the right nasal cavity. There is no definite communication of this lesion with the intracranial structures. No defect in the skull base is identified on this study.
There is no focal area of altered signal intensity in the brain parenchyma.
Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. No obvious vascular anomaly is identified on this study.
The myelination pattern is normal for the patients age.
The MRI features suggest approximately 2.1 x 4.2 x 2.3 cms sized mass lesion in the right nasal cavity with signal characteristics as described. There is no evidence of herniation of the intracranial structures into this mass lesion. No definate defect in the skull base is identified on this study. A nasal glioma/dermoid/epidermoid cyst may be considered as likely possibilities. A meningocele, however, cannot be entirely excluded.
