On individual evaluation, Patient G had prominent right-sided dull orbital pain for 3 weeks with right-sided headache and diplopia for 1 week. Examination showed ipsilateral sixth nerve paresis. Investigations like Complete Blood Count, Complete Metabolic Panel, Chest X-ray, ANA, CSF Analysis (including Adenosine deaminase), ESR, and CRP were negative. MRI showed a single hypointense extra-axial lesion in right anteromedial temporal region, anterolateral to ipsilateral cavernous sinus. The lesion appeared to partially encase right sixth cranial nerve and approaching right superior orbital fissure.
Patient V had similar complaints of right-sided headache for 4 weeks and diplopia for 1 week. Examination showed complete paralysis of ipsilateral sixth nerve palsy. Similarly, investigations were negative (including serum ACE levels). MRI revealed a single extra-axial hypointense lesion along right medial temporal region along with partial invasion of ipsilateral cavernous sinus. Mild asymmetric thickening of right fifth and sixth cranial nerves was seen.
