Name of the Patient : Abc XyzGaolmn / F / 42 yrs.
Referred by : Dr. Abc Xyzhalani.
Examination : M.R.I. of the Sella & Perisellar Region.

CLINICAL PROFILE :

C/O swelling over the RLE (since 5 years) with change in voice since 2 months.
Known hypertensive/diabetic. On Rx.

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.

After administration of contrast the following parameters were used :

5 mm thick T1 Weighted axial images with magnetization transfer.

3 mm thick T1 Weighted sagittal and coronal images.

3 mm thick T1 Weighted delayed coronal images were also obtained.

OBSERVATION :

There is seen a well-marginated, approximately 8.0 x 7.0 x 6.0 mms sized hypointense lesion on the T1 Weighted images in the anterior pituitary gland to the left of the midline. This lesion appears hyperintense on the T2 Weighted images.

The posterior pituitary gland reveals normal hyperintense signal on the T1 Weighted images. The pituitary stalk is in the midline. The hypothalamus is unremarkable.

R>
The cavernous sinuses and the suprasellar cistern are also unremarkable.

After administration of contrast, the lesion in the anterior pituitary gland initially does not enhance. On the delayed images this lesion fills up with contrast.

The T2 Weighted axial images of the brain reveal prominent perivascular spaces (which appear as confluent lesions) in the cerebellar hemispheres bilaterally. There is no abnormal enhancement in the brain parenchyma or the meninges.

Inflammatory changes are noted in the left maxillary sinus and sphenoid sinus.

IMPRESSION :

An approximately 8.0 x 7.0 x 6.0 mms sized lesion in the anterior pituitary gland to the left of the midline with enhancing pattern as described most likely represents a pituitary microadenoma.
