Name of the Patient : Abc XyzZ. Kshirslmn / M / 38 yrs.
Referred by : Dr. Abc Xyzhtekar.
Examination : Intracranial and Neck M.R.A.

CLINICAL PROFILE :

C/O twitching over the right eye since 3 years.

EXAMINATION :

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

Intracranial and neck MRA were performed with 3D TOF and 2D TOF sequences, respectively.

OBSERVATION :

There is no focal area of altered signal intensity within the brain parenchyma.

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

Incidental note is made of pansinusitis.

INTRACRANIAL MRA :

The A1 segment of the right anterior cerebral artery is hypoplastic.

The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized left anterior cerebral, middle cerebral, basilar, vertebral and posterior cerebral arteries also show normal signal, calibre and wall margins. No obvious aneurysm or vascular malformation is identified. A vascular loop (the left vertebral artery) is seen to indent the root exit zone of the left seventh and eighth cranial nerve complex.

NECK MRA :

The common carotid arteries and their extracranial branches appear normal bilaterally. There are no vessel wall irregularities or stenosis of the vessels noted.

IMPRESSION :

A vascular loop (left vertebral artery) indenting the root exit zone of the left seventh and eighth cranial nerve complex.

No other significant abnormality is detected on the intracranial and neck MRA on this study.
