Name of the Patient : Abc Xyzyam Mlmn / M / 65 yrs.
Referred by : Dr. Abc Xyztrak.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O right sided weakness with slurred speech since 00.00.0000.
H/O similar complaints in 0000 & 0000.
Known diabetic/hypertensive. On Rx.
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 and Fast Scan (T2 *) coronal images.
5 mm thick T1 Weighted sagittal images.
There is evidence of a space-occupying lesion which is hyperintense on all the pulse sequences and measuring approximately 1.7 x 3.5 x 1.4 cms within the left cerebellar hemisphere. It is seen to indent the left lateral aspect of the fourth ventricle and would represent a subacute bleed. Few areas at the periphery of this lesion are seen to bloom on the Fast Scan (T2 *) images.
There is an area of hypointensity, best appreciated on the Fast Scan (T2 *) images within the left thalamus and this most likely represents haemosiderin, the result of a previous bleed.
There are areas of hyperintensity on the proton, T2 Weighted and FLAIR images within the lentiform nuclei and the periventricular and fronto-parietal white matter bilaterally. These are iso to hypointense on the T1 Weighted images and are ischemic in etiology.
- 2 - Scan-00005
Hyperintense signal is located within the posterior third ventricle and aqueduct on the proton density and T2 Weighted images and would represent turbulent flow.
There is fullness of the third and both the lateral ventricles.
There is slight prominence of the basal cisternal spaces, cerebral cortical sulci and cerebellar folia bilaterally.
There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
Inflammatory changes are seen in both maxillary sinuses and sphenoid sinus.
The MRI features are suggestive of :
1. A space-occupying lesion measuring approximately 1.7 x 3.5 x 1.4 cms within the left cerebellar hemisphere and would represent a subacute bleed.
2. Altered signal within the left thalamus most likely represents haemosiderin, the result of a previous bleed.
3. Areas of altered signal within the lentiform nuclei and the periventricular and fronto-parietal white matter bilaterally
are ischemic in etiology.
