Name of the Patient : Abc Xyzahadur Slmn / M / 50 yrs.
Referred by : Dr. Abc Xyzchale.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O left sided hemiparesis with altered sensorium since 4 days.
H/O left sided hemiparesis in 0000 and 0000 from which patient recovered.
Known hypertensive.

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 and Fast Scan (T2 *) coronal images.

5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There are hypointense areas on the T1 Weighted images in the ventro-medial thalami bilaterally, subthalamus extending into the upper midbrain on the right side. These are seen to turn hyperintense on the proton, T2 Weighted and FLAIR images and represents a recent infarct (scans 108.9, 10, 103.9 to 12, 102.9 to 12, 106.11).

Similar smaller areas are seen in bilateral corona radiata and centrum semiovale and represent ischemic changes.

Lacunar infarcts are seen in corona radiata with surrounding gliotic changes.







A linear hypointense signal on the T1 Weighted images is noted in the right external capsule which is seen to turn hyperintense on the proton and T2 Weighted images and blooms on the Fast Scan (T2 *) images and represents residual hemosiderin, the result of a previous bleed (scans 104.12, 106.12).

Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures. The vertebro-basilar system is ectatic.

IMPRESSION :

1. Recent infarcts in the ventro-medial thalami bilaterally, subthalamus extending into the upper midbrain on the right side.

2. Residual hemosiderin in the right external capsule.

3. Lacunar infarcts in the corona radiata.
