Name of the Patient : Abc XyzLokhlmn / M / 40 yrs.
Referred by : Dr. Abc Xyzrges.
Examination : Intracranial M.R.A.

CLINICAL PROFILE :

C/O giddiness since 3 days with vomiting, ptosis on the left side and altered sensorium.

EXAMINATION :

The brain was screened with 5 mm thick T2 Weighted axial images.

Intracranial MRA was performed with a 3D TOF sequence.

OBSERVATION :

There are ill-defined, hyperintense areas on the T2 Weighted images in the left lentiform nucleus, left thalamus and left temporo-parieto-occipital parafalcine cortex. These most likely represent ischemic lesions.

There are bilateral, small, subdural collections over the cerebral convexities on either side with a maximum width of about 7.0 mms. These lesions are hyperintense to CSF on all the pulse sequences. Focal hyperintensity within these lesions on the T1 Weighted images which appears hypointense on the T2 Weighted images are noted in the high parietal regions bilaterally and would represent hemoglobin breakdown products.

There is mild fullness of the third both the lateral ventricles. The fourth ventricle is normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.

Inflammatory changes are noted in the paranasal sinuses and in the mastoid air cells bilaterally.






INTRACRANIAL MRA :

The intracranial segment of the right vertebral artery appears hypoplastic.

The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized anterior cerebral, middle cerebral, basilar, left vertebral and posterior cerebral arteries also show normal signal, calibre and wall margins. No obvious aneurysm or vascular malformation is identified.

IMPRESSION :

1. Altered signal in the left lentiform nucleus, left thalamus and left temporo-parieto-occipital parafalcine cortex most likely represents ischemic lesions.

2. Bilateral, small, subdural collections/hematomas overlying the cerebral convexities on either side with a maximum width of about 7.0 mms.

3. No significant abnormality is detected on the intracranial MRA on this study.
