Name of the Patient : Abc XyzBharlmn / F / 18 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
H/O left LMN facial palsy on 00.00.00.
M.R.I of the brain was performed using the following parameters :
5 mm thick T1 Weighted, proton and T2 Weighted axial images.
5 mm thick FLAIR coronal images.
There are still seen diffuse, irregularly defined areas of hypointensity on the T1 Weighted images which turn hyperintense on the proton and T2 Weighted images within the left petrous bone. It is also seen to involve the middle ear, mastoid air cells and internal ear on the left side. There is erosion of the bone with extension into the left temporal fossa with involvement of the meninges along the postero-inferior and medial aspect of the left temporal bone.
Both the lateral, third and the fourth ventricles are normal. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
The MRI features are suggestive of a pathologic process involving the petrous temporal bone on the left side as described.
As compared to the previous MRI (study no:00003) dated 00.00.00, there is significant reduction of the lesion.
