Name of the Patient : Abc XyzSinlmn / F / 26 yrs.
Referred by : Dr. Abc Xyzmpat / Dr. Abc Xyzdar.
Examination : M.R.I. of the Sella & Perisellar Region.
CLINICAL PROFILE :
Serum Prolaction level = 41ng.
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 contrast administration, 3 mm thick T1 Weighted coronal, sagittal and axial images (with magnetization transfer) were obtained and 5 mm thick T1 Weighted axial images with magnetization transfer were obtained through the brain.
Delayed 3 mm thick T1 Weighted coronal images were also obtained through the sella.
There is seen a very small, approximately 4.0 mms diameter sized well-defined, hypointense lesion on the T1 Weighted images on the surface of the anterior pituitary gland, to the left of the midline, close to the cavernous segment of the left internal carotid artery. This lesion appears hyperintense on the T2 Weighted images (scans 104.7-8 & 105.7-8). Minimal superior convexity of the anterior pituitary gland is noted at that level.
After administration of contrast, on the early post-contrast images, there is rim-enhancement of the above described lesion (scan 106.6) on the delayed post-contrast images, the lesion fills up with contrast (scan 110.6).
The posterior pituitary gland reveals normal hyperintense signal on the T1 Weighted images. The pituitary stalk is in the midline. The hypothalamus is unremarkable.
The cavernous sinuses and the suprasellar cisterns are unremarkable.
No abnormality is detected in the brain parenchyma. The ventricular system is unremarkable. There is no midline shift.
Inflammatory changes are noted in the sphenoid sinus on the left.
A septum is also noted in the sphenoid sinus.
A very small, approximately 4.0 mms diameter sized well-defined lesion on the surface of the anterior pituitary gland, to the left of the midline, close to the cavernous segment of the left internal carotid artery follows the enhancing pattern of a pituitary microadenoma.
The possibility of a Rathkes cleft cyst seems less likely.
