Depending on the inflammatory infiltrate location, patients might present with various nonspecific symptoms that include nerve compression in cavernous sinus, partial or complete ophthalmoplegia indicating superior orbital fissure involvement, or loss of vision indicating optic nerve involvement; isolated trochlear nerve paresis has also been described (4).
This condition might be explained by the high invasion potential of the non-specific granulomatous inflammation located in the cavernous sinus, superior orbital fissure, or orbital apex.
In addition, common abnormalities consist of widening of orbital fissures, hypoplasia of sinuses, defects of greater wing of sphenoid and roof of orbit and enlargement of the middle cranial fossa.
THS is caused by a non-specific inflammatory process in the cavernous sinus or superior orbital fissure (SOF).
Specific diagnostic criteria have been recommended by the International Headache Society which includes unilateral headache; granulomatous inflammation of the cavernous sinus and superior orbital fissure or orbit seen on magnetic resonance imaging or biopsy; paresis of one or more of the ipsilateral third, fourth, and/or sixth cranial nerves; evidence of causation demonstrated by both headache preceded by oculomotor paresis by less than 2 weeks or developed with it and headache that is localized around the ipsilateral brow and eye; and symptoms not better accounted for by an alternative diagnosis [9].
Neuroradio- diagnostic examinations showed that orbital cellulitis had greatly reduced into inflammation in the orbital apex, superior orbital fissure and cavernous sinus on the right side (Figure-1, 2).
The intracranial extension has been described through the three major openings in the posterior aspect of the orbit, which include the superior orbital fissure, optic canal and the inferior orbital fissure.
Knowing the precise location of the optic strut and its variations are very important while analyzing CT images, since it represents a valuable landmark in proper evaluation and differentiation of the optic canal, superior orbital fissure and anterior clinoid process on coronal and axial scans [13].
Tolosa-Hunt syndrome (THS) is a rare disorder indicated by recurrent painful ophthalmoplegia caused by non-specific inflammation of the cavernous sinus or superior orbital fissure (SOF).

Typically, a fracture line extends from the inferior orbital fissure anteromedially along the orbital process of the maxilla, toward the infraorbital rim.
