Name of the Patient : Abc XyzKhandelmn / M / 37 yrs.
Referred by : Dr. Abc Xyzrani.
Examination : M.R.I. of the Sella & Perisellar Region.
CLINICAL PROFILE :
H/O transphenoidal excision of acidophilic macroadenoma in 0000.
Has received radiotherapy (26 sittings).
At present has no complaints. 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.
There is widening of the floor of the sella. There is evidence of an intermediate to hypointense signal intensity lesion on the T1 Weighted images along the undersurface of the pituitary gland. This lesion appears hyperintense on the T2 Weighted images. This lesion extends into the sphenoid sinus more to the right of the midline. A portion of the anterior pituitary gland is seen along the superior margin of this lesion as an intermediate signal intensity structure on the T1 Weighted images, which turns relatively hypointense 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, the suprasellar cistern and the cavernous sinuses are unremarkable on either side.
Inflammatory changes are noted in the left maxillary antrum and sphenoid sinus. Septae are seen within the sphenoid sinus.
Screening, T2 Weighted axial images of the brain do not reveal any significant feature of note. CT focus within the pons on the right is most likely artifactual.
1. Post-operative status.
2. Lesion along the undersurface of the pituitary gland as described, suggests cystic/necrotic changes in the previous pituitary adenoma. A portion of the normal anterior pituitary gland is seen along the superior margin of the cystic changes.
As compared to the previous MRI dated 00.00.0000 (Scan No.0000), cystic/necrotic changes are now noted in the previously identified residual pituitary adenoma.
