Name of the Patient : Abc Xyzavlmn / F / 30 yrs.
Referred by : Dr. Abc Xyzanapathy.
Examination : M.R.I. of the Sella & Perisellar Region.
CLINICAL PROFILE :
Known C/O Cushings disease. Transphenoidal excision of the tumor was done in 0000.
ACTH - 125 pg/ml.
For follow up.
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 through brain parenchyma.
3 mm thick T1 Weighted sagittal and coronal images through the sella and perisellar region.
There is a subtle isointense signal on the T1 Weighted images along the floor of sella more to the left of the midline which turns hypointense on the T2 Weighted images with deviation of the stalk to the left. The posterior pituitary gland is well seen to the left of the midline (scan 105.4). On contrast administration, there is homogeneous enhancement of this lesion (scans 103.5, 103.6, 105.5, 107.6, 107.7).
- 2 - Scan-00002
There is no focal area of altered signal intensity in 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. No obvious vascular anomaly is identified on this study.
After contrast administration, there is no other area of abnormal enhancement in the brain parenchyma or along the meninges.
The MRI features are suggestive of :
1. Post-operative status.
2. Altered signal along the floor of sella may represent remnant of the pituitary gland with deviation of the stalk to the left.
No previous investigations were available for comparison.
