Name of the Patient : Abc Xyzng P. Dhulmn / M / 48 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
H/O sudden onset of diminished vision with diplopia on looking to the left with frontal headaches and heaviness of eyes.
M.R.I of the brain was performed using the following parameters :
5 mm thick T1 Weighted, proton and T2 Weighted axial images.
5 mm thick FLAIR coronal images.
3 mm thick T1 Weighted and STIR coronal images.
5 mm thick T1 Weighted sagittal images.
There is evidence of a fairly well-defined space-occupying lesion within the left cavernous sinus and having a diameter of approximately 2.0 cms. This lesion shows mixed signal characteristics on all the pulse sequences with areas of signal void which most likely represents flowing blood. There is scalloping of the sella/sphenoid wall adjacent to the left cavernous sinus.
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.
A polyp is seen in the left maxillary sinus and septae are noted in the sphenoid sinus.
The MRI features are suggestive of a space-occupying lesion within the left cavernous sinus and having a diameter of approximately 2.0 cms. This most likely represents an aneurysm arising from the cavernous component of the left internal carotid artery. This is less likely to represent a neoplastic process (eg. meningioma).
