Surrounding the
cavernous sinus are important nerves called the cranial nerves because they originate from the brain within the cranium (skull bone).
Treatment of a carotid cavernous fistula via direct transovale
cavernous sinus puncture.
(D) Sagittal MRI indicating compression of the dura (D) superiorly and the
cavernous sinus (CS) superoposteriorly.
CSF leak was the commonest complaint in 10(55.5%) of these patients which did not require any surgical intervention CSF leakage could occur when
cavernous sinus and diaphragmatic recesses are explored but mostly this resolves by itself.
The potential mechanisms underlying headache in PA are meningeal irritation, duramater compression, enlargement of the sella turcica walls, or involvement of the superior division of the trigeminal nerve inside the
cavernous sinus [1].

cavernous sinus: the infectious hypothesis revisited," Headache, vol.
Following initiation of heparin infusion, a CT venogram (CTV) confirmed the presence of thrombosis along with a filling defect in the L
cavernous sinus (Figure 3).
Trigeminal schwannomas in the
cavernous sinus usually arise in the Meckel's cave and demonstrate secondary anterior extension (2).
A follow-up MRI in patient 5 after three months showed decreased signal intensity and enhancement of the affected
cavernous sinus.
A small haematoma extended through to the
cavernous sinus. All the paranasal sinuses were normal.
Baseline cranial contrast enhanced MRI detected a nonspecific inflammatory granulomatous lesion in the right
cavernous sinus extending basally towards the right trigeminal cave (Meckel's cave) and anteriorly towards the apex of the right orbit.
This inflammatory lesion may propagate endocranially, resulting in acute meningitis, epidural abscess, subdural empyema,
cavernous sinus trombophlebitis, cerebritis, and frontal lobe abscess of the brain.
