Name of the Patient : Abc Xyzal Gokalgalmn / M / 69 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O right sided weakness since 15 days.
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.
There is a well-defined, approximately 3.0 x 2.3 x 2.8 cms sized mass lesion in the left thalamus, extending superiorly into the left corona radiata. This lesion has a hyperintense periphery and a hypointense centre on the T1 Weighted images. This is seen to turn heterogeneously hyperintense on the T2 Weighted and Fast Scan (T2 *) images, with a peripheral hypointense rim on the Fast Scan (T2 *) images. There is mild perilesional edema with indentation upon the body of the left lateral and third ventricles. There is probable dissection of this bleed into the left lateral ventricle.
There are ill-defined hyperintense areas on the proton, T2 Weighted and FLAIR images in the posterior parietal deep white matter bilaterally. These lesions appear iso to hypointense to white matter on the T1 Weighted images and most likely represent ischemic changes.
There is mild fullness of both the lateral and third ventricles.
The fourth ventricle is normal. There is prominence of the cerebral cortical sulci. The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
An approximately 3.0 x 2.3 x 2.8 cms sized mass lesion in the left thalamus extending superiorly into the left corona radiata represents a subacute hematoma.
As compared to the previous T2 Weighted axial images in the MRA study no:00000 dated 00.00.00, there is a slight decrease in the perilesional edema around the lesion. A hemosiderin rim is now identified around the lesion. There is however, no significant change in the size of the lesion and the ventricles on this study.
