Cavernous Sinus Thrombosis
Diagnosis of Cavernous Sinus Thrombosis
MRI or CT Cavernous sinus thrombosis is often misdiagnosed because it is rare. It should be considered in patients who have signs consistent with Preseptal and Orbital Cellulitis . Features that distinguish cavernous sinus thrombosis from orbital cellulitis include cranial nerve dysfunction, bilateral eye involvement, and mental status changes. Diagnosis is based on neuroimaging. MRI is the better study, but CT is also helpful. Contrast-enhanced MR venogram (MRV) and CT venogram are more sensitive than either CT or MRI. Useful adjunct testing may include blood cultures and Lumbar Puncture (Spinal Tap) .
