Name of the Patient : Abc Xyza lmn / F / 21 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : Intracranial M.R.A.
CLINICAL PROFILE :
C/O headaches and occasional giddiness since 00.00.0000.
The brain was screened with 5 mm thick T2 Weighted axial images, 3 mm thick T1 Weighted and T2 Weighted coronal images and 5 mm thick T1 Weighted sagittal images.
Intracranial MRA was performed with a 3D TOF sequence.
There is seen an approximately 1.2 x 1.0 x 1.6 cms sized well-marginated mass lesion in the anterior pituitary gland extending into the suprasellar region. This lesion is of intermediate signal on the T1 Weighted images and is relatively hypointense on the T2 Weighted images. Minimal indentation and superior displacement of the optic chiasma is noted. There is no extension of the lesion into the cavernous sinus on either side. The posterior pituitary gland shows normal hyperintense signal on the T1 Weighted images. The pituitary stalk is not well-identified. The hypothalamus is unremarkable.
There is no focal area of altered signal intensity in the brain parenchyma per se.
Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable.
INTRACRANIAL MRA :
There is slight concentric narrowing of the cavernous segment of the left internal carotid artery.
The petrous, cavernous and supraclinoid segments of the right internal carotid artery and the petrous and supraclinoid segments of the left internal carotid artery show normal signal and calibre. The visualized anterior cerebral, middle cerebral, basilar, vertebral and posterior cerebral arteries also show normal signal, calibre and wall margins. No obvious aneurysm or vascular malformation is identified.
1. An approximately 1.2 x 1.0 x 1.6 cms sized mass lesion in the anterior pituitary gland extending into the suprasellar cistern as described, most likely represents a pituitary macroadneoma.
2. Slight concentric narrowing of the cavernous segment of the left internal carotid artery.
3. No other significant abnormality is detected on the intracranial MRA on this study.
