Name of the Patient : Abc Xyzt Slmn / M / 38 yrs.
Referred by : Dr. Abc Xyzni.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O severe headaches since 1 month.
C/O diminished vision in both eyes, (right more than left) since 10-12 days.
O/E papilloedema BE.
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.
There is no focal area of altered signal intensity in the brain parenchyma.
There is a hyperintense signal on all the pulse sequences within the transverse and sigmoid sinuses on the right side and within the anterior and midsegments of the superior sagittal sinus and in the posterior cortical veins.
Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.
The optic nerves were screened with 4 mm thick STIR coronal images and show normal signal intensity.
Inflammatory changes are seen within the right mastoid air cells, right maxillary sinus and ethmoidal air cells.
The MRI features are suggestive of altered signal within the transverse and sigmoid sinuses on the right side and within the anterior and midsegments of the superior sagittal sinus and posterior cortical veins as described. This may represent venous sinus thrombosis/slow flow (thrombus more likely in the right transverse and sigmoid sinuses especially as seen on the limited MRV. The superior sagittal sinus may have partially recanalised).
