Name of the Patient : Abc Xyz Shlmn / M / 43 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
H/O sudden loss of memory with disorientation for 15 minutes, 5 months back.
Now C/O heaviness of head and eyes with increase sleep.
H/O DM/HT. Irregular Rx.
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 T1 Weighted and FLAIR coronal images.
5 mm thick T1 Weighted sagittal images.
OBSERVATION :
There is seen an approximately 2.7 x 3.4 x 6.0 cms sized well marginated, extra-axial mass lesion in the right high fronto-parietal, parafalcine region (in the interhemispheric fissure on the right). This lesion follows CSF signal on all the pulse sequences. Resultant indentation on the underlying brain parenchyma is noted.
There are ill-defined, hyperintense areas on the proton T2 Weighted and FLAIR images in the subcortical white matter in the frontal regions bilaterally and in the left posterior parietal region. These lesions appear isointense to normal white matter on the T1 Weighted images.
There is an ill-defined, hyperintense signal on the T1 Weighted images in the globus pallidus bilaterally, extending into the subthalamic region and into the cerebral peduncles bilaterally. This lesion appears isointense to normal grey matter on the proton, T2 Weighted and FLAIR images.
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.
IMPRESSION :
1. An approximately 2.7 x 3.4 x 6.0 cms sized CSF signal intensity, extra-axial mass lesion in the right high fronto-parietal, parafalcine region (in the interhemispheric fissure) as described, most likely represents an arachnoid cyst.
2. Altered signal in the subcortical white matter in the frontal regions bilaterally and in the left posterior parietal region may represent ischemic changes.
3. Altered signal in the globus pallidus bilaterally, extending into the subthalamic region and into the cerebral peduncles bilaterally may represent paramagnetic substance deposition. Such changes are seen in the hepato-cerebral syndrome.
As compared to the previous MRI dated 00.00.0000, there is no significant change noted in the size of the right high fronto-parietal parafalcine lesion.
