Name of the Patient : Abc Xyzl T. lmn / M / 54 yrs.
Referred by : Dr. Abc Xyzdar / Dr. Abc Xyzah.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

Alleged H/O vehicular accident on 00.00.00
C/O altered sensorium since then.

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 is still seen thickening of the gyri which appear hypointense to the grey matter on the T1 Weighted images in the left anterior temporal lobe, right temporal lobe laterally and the left frontal lobe. These are seen to turn hyperintense on the proton, T2 Weighted and Fast Scan (T2 *) images. Few hyperintense areas are seen on the T1 Weighted images which are seen to remain hyperintense on the proton, T2 Weighted and FLAIR images and would represent methaemoglobin. There is effacement of the sulci in that region with surrounding edema. There is mass effect with posterior displacement of the frontal horn of the left lateral ventricle. Slight shift of the falx to the opposite side is noted in this region (scans 104.11-12. 102.11-12., 103.11-12)

Small sliver of haemorrhagic subdural collections is seen in the fronto-temporo-parietal regions bilaterally.



Suspicious fractures of the temporal bones bilaterally are noted with altered signal in the mastoid air cells bilaterally and middle ear cavity. Haemorrhage is also noted in the sphenoid sinus.

The third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. No obvious vascular anomaly is identified on this study.

IMPRESSION :

The MRI features are suggestive of :

1. Haemorrhagic contusions in the left anterior temporal lobe, right temporal lobe laterally and in the left frontal lobe.

2. Small subdural collection in the fronto-temporo-parietal regions bilaterally.

As compared to the previous MRI dated 00.00.00 (study no.00001),

a. There is slight increase in the subdural collections bilaterally.

b. Presence of edema is noted around the contusions which is seen to cause mass effect with indentation on the frontal horn of the left lateral ventricle and slight shift of the falx to the opposite side.

c. The contusions now appear in the subacute stage.
