Name of the Patient : Abc XyzSlmn / F / 55 yrs.
Referred by : Dr. Abc Xyzrani.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O left hemifacial spasm.
EXAMINATION :
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.
3 mm thick T1 Weighted coronal images.
After administration of contrast the following parameters were used :
5 mm thick T1 Weighted axial images with magnetization transfer.
3 mm thick T1 Weighted coronal images.
5 mm thick T1 Weighted sagittal images.
Limited MR angio sequence was obtained through the region of interest.
OBSERVATION :
There are ill-defined, hyperintense areas on the proton, T2 Weighted and Flair images in the subcortical and deep white matter in the fronto-parietal regions bilaterally and in the pons. These lesions appear iso to hypointense to normal white matter on the T1 Weighted images and most likely represents ischemic changes.
There is mild prominence of the cerebellar folia.
Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.
A vascular loop is seen to indent the root exit zone of the left seventh and eighth cranial nerve complex (scans 107.7, 107.8, 117.7). There is ectasia of the vertebro-basilar system.
After contrast administration there is no focal abnormal area of enhancement in the brain parenchyma or the meninges or along the seventh and eighth cranial nerve complex on either side.
IMPRESSION :
1. Altered signal in the subcortical and deep white matter in the fronto-parietal regions bilaterally and in the pons most likely represents ischemic changes.
2. A vascular loop indenting root exit zone of the seventh and eighth cranial nerve complex.
