Name of the Patient : Abc Xyznt Salmn / M / 30 yrs.
Referred by : Dr. Abc Xyzrani.
Examination : M.R.I. of the Sella & Perisellar Region.

CLINICAL PROFILE :

To r/o pituitary v/s infrasellar v/s hypothalamus lesion.

EXAMINATION :

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

3 mm thick T1 Weighted and T2 Weighted coronal images.

3 mm thick T1 Weighted sagittal images.

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

5 mm thick T1 Weighted sagittal images.

After administration of contrast the following parameters were used :

5 mm thick T1 Weighted axial images with magnetization transfer.

3 mm thick T1 Weighted coronal and sagittal images.

OBSERVATION :

The posterior pituitary reveals its normal hyperintense signal, slightly more to the right of the midline (scans 105.7-8).

The anterior pituitary gland appears normal in size and shows a hyperintense signal on the T1 Weighted images (as compared to normal white matter). This signal appears significantly hypointense (as compared to normal white matter) on the T2 Weighted images. No focal mass lesion is identified in the anterior pituitary gland.

- 2 - Scan-00000


There is a hypointense signal on the T1 Weighted images in-between the anterior and posterior lobes of the pituitary gland (probably the intermediate lobe). This lesion appears hyperintense on the T2 Weighted images and may represent pars intermedia cyst.

The pituitary stalk is in the midline. The hypothalamus is unremarkable.

The left lateral ventricle is prominent as compared to the right, which may be a normal variant.

After contrast administration there is no abnormal area of enhancement within the sella and perisellar region.

There is no significant abnormality detected within the brain parenchyma per se on this study.

IMPRESSION :

1. Hyperintense signal of the anterior pituitary gland, on the T1 Weighted images as described, is not specific for a single etiology. Such signal change is noted in neonates and pregnant women due to lactotroph hypertrophy and increased protein synthesis in the pituitary gland. Such changes are also noted in patients undergoing parenteral hyperalimentation or in patients with hepatic dysfunction.

2. Cystic lesion between the anterior and posterior lobes of the pituitary gland may represent a pars intermedia cyst (a non-functional cyst).

OBSERVATION :

The posterior pituitary does not reveal its normal hyperintense signal.

The anterior pituitary gland appears normal in size and shows hyperintense signal on the T1 Weighted images which is seen to follow fat signal intensity characteristics on the T2 Weighted images.



The pituitary stalk is in the midline. The hypothalamus is unremarkable.

The left lateral ventricle is prominent as compared to the right and which may be a normal variant.

After contrast administration there is no abnormal area of enhancement within the sella and perisellar region.

IMPRESSION :

Normal study of the Pituitary.
