Name of the Patient : Abc Xyzet Bhalmn / M / 3 yrs.
Referred by : Dr. Abc Xyzhalani.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O optic atrophy with delayed milestones.

EXAMINATION :

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

5 mm thick T1 Weighted and T2 Weighted axial images.

3 mm thick T1 Weighted and T2 Weighted coronal images.

3 mm thick T1 Weighted sagittal images.

OBSERVATION :

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

There is cerebellar tonsillar herniation through the foramen magnum.

There is mild to moderate dilatation of the third and both the lateral ventricles. There is marked dilatation of the chiasmatic and infundibular recesses of the third ventricle with resultant expansion of the proximal pituitary stalk. The pituitary gland is seen to be decreased in height (height of 1.0 mm). There is effacement of the cerebral cortical sulcal spaces

The fourth ventricle is normal. No obvious vascular anomaly is identified on this study.

IMPRESSION :

1. Cerebellar tonsillar herniation through the foramen magnum suggests a Chiari malformation.

2. Mild to moderate dilatation of third and both the lateral ventricles with marked dilatation of the chiasmatic and
infundibular recesses of the third ventricle.

3. Decreased height of the pituitary gland.
