Name of the Patient : Abc Xyz Valmn / F / 55 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
H/O cataract surgery (right on 00.00.00 and left on 00.00.00).
C/O loss of vision of the left eye 15 days after operation and decreased vision of the right eye.
M.R.I of the brain was performed using the following parameters :
5 mm thick T2 Weighted axial images.
4 mm thick T1 Weighted and FLAIR coronal images.
5 mm thick T1 Weighted and 4 mm thick T2 Weighted sagittal images
There is seen a fairly large, multiloculated, extra-axial mass lesion in the suprasellar region, extending into the inferior frontal regions bilaterally. This lesion measures approximately 4.5 x 5.0 x 3.0 cms. This lesion has a heterogeneous signal intensity with the posterior half of the lesion appearing slightly hyperintense to CSF on all the pulse sequences and the anterior half of the lesion following fat signal characteristics on all the pulse sequences.
Posteriorly the lesion extends into the interpeduncular cistern with compression and posterior displacement of the upper brainstem. Probable encasement of the distal basilar artery is noted. Inferiorly the lesion extends into the sella turcica with slight flattening of the pituitary gland. The pituitary stalk and the optic chiasma are not well identified separately from the lesion though they seem to be displaced superiorly,
posteriorly and slightly to the right of the midline. Superiorly the lesion indents upon the hypothalamus. Anteriorly the lesion extends into the subfrontal region. Laterally the lesion indents the left medial temporal lobe.
There is no focal area of altered signal intensity within the brain parenchyma per se.
There is mild fullness of both the lateral ventricles. The third ventricle is indented by the lesion and pushed to the right side. The fourth ventricle is normal.
A fairly large, approximately 4.5 x 5.0 x 3.0 cms. sized multiloculated, heterogeneous signal intensity mass lesion in the suprasellar region with extensions as described, is not specific for a single etiology. A craniopharyngioma or an epidermoid/dermoid cyst should be considered as a differential diagnosis.
