Name of the Patient : Abc Xyzed Patralmn / M / 50 yrs.
Referred by : Dr. Abc Xyzwant.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O right sided trigeminal neuralgia.

EXAMINATION :

M.R.I of the brain was performed using the following parameters :

5 mm thick T1 Weighted, proton and T2 Weighted axial images.

3 mm thick T1 Weighted coronal images.

5 mm thick T1 Weighted sagittal images.

A limited MRA sequence was obtained through the midbrain.

OBSERVATION :

A large vascular loop (ectatic basilar artery) is seen to indent the right ventral aspect of the pons and deform the cisternal component of the right trigeminal nerve. Also seen is indentation upon the root entry zone of the right trigeminal nerve (scans 105.6 to 105.8, 102.6-7, 665.6-7).

Small areas of hyperintensity on the proton and T2 Weighted images are seen within the white matter in the fronto-parietal lobes bilaterally. These are iso to hypointense to normal white matter on the T1 Weighted images and are most likely ischemic in etiology.

There is mild prominence of the cerebral cortical sulci and cerebellar folia bilaterally. There is fullness of both the lateral ventricles.

The diploic space of the skull is more prominent than usual.


IMPRESSION :

The MRI features are suggestive of a large vascular loop (ectatic basilar artery) indenting the right ventral aspect of the pons and deform the cisternal component of the right trigeminal nerve and indentation upon the root entry zone of the right trigeminal nerve.
