Name of the Patient : Abc XyzAli Essa Al-Sablmn / F / 40 yrs
Referred by : Dr. Abc Xyzrani.
Examination : M.R.I. of Sella & Perisellar Region.

CLINICAL PROFILE :

C/O progressive loss of vision of the left eye since 6-7 years.

EXAMINATION :

M.R.I of the sella & 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.

After contrast administration, the sella and perisellar region was scanned with 3 mm thick T1 Weighted sagittal and coronal images and 3 mm thick T1 Weighted sagittal images with fat saturation. The brain was screened with 5 mm thick T2 Weighted axial images with magnetization transfer after contrast administration.

OBSERVATION :

There is seen a well-marginated, lobulated, approximately 2.0 x 1.5 x 2.8 cms sized intermediate signal intensity mass lesion on the T1 Weighted images in the sella and suprasellar region, extending posteriorly along the floor of the anterior cranial fossa (along the planum sphenoidale). This lesion appears isointense to grey matter on the T2 Weighted images.

The superior margin of the anterior pituitary gland is indented by the lesion with the gland being pushed along the floor of the sella. The posterior pituitary gland shows a normal hyperintense signal on the T1 Weighted images. The pituitary Scan-00009



stalk is not well-identified separately from the lesion. The optic chiasma is displaced superiorly by the lesion. The left optic nerve is probably atrophied and shows a hyperintense signal on the T2 Weighted images.

There is no extension of the lesion into the cavernous sinuses on either side.

There is no ballooning of the sella. Suspicious erosion of the planum sphenoidale is noted to the left of the midline (scans 103.7, 107.7).

After contrast administration, there is uniform enhancement of the above described mass lesion and the pituitary gland. Though it is difficult to separate the mass lesion from the pituitary gland, a probable clevage plane exists between the two, better appreciated posteriorly.

The screening images of the brain do not reveal any significant feature of note, though mild ventricular fullness is noted.

IMPRESSION :

An approximately 2.0 x 1.5 x 2.8 cms sized uniformly enhancing mass lesion in the sella and suprasellar region and along the floor of the anterior cranial fossa as described is not specific for a single etiology.

This most probably represent planum sphenoidale meningioma. A pituitary adenoma cannot be entirely excluded though less likely. Left optic atrophy with altered signal is also noted.

As compared to the previous MRI dated 00.00.00, there is no significant change noted.
