Axial and coronal T2 demonstrate high T2 signal expanding dural sheath of the optic nerves bilaterally (i.e. dilated CSF spaces around the optic nerves bilaterally). Partially empty sella. No area of abnormal signal intensity elicited in supra or infratentorial regions.
The MRI findings are suggestive of idiopathic intracranial hypertension (pseudotumour cerebri). No evidence of dural venous sinuses thrombosis, hydrocephalus or space occupying lesion.
