Overview
Magnetic resonance imaging (MRI) with MR venography is the gold standard test for the diagnosis of cavernous sinus thrombosis.[1][2][3]
The following findings on performing MRI are confirmatory for cavernous sinus thrombosis:
- T1 and T2
- Absent flow void
- Signal characteristics vary depending on the age of the thrombus but will be abnormal.
- Contrast-enhancement or lack of is not a reliable indicator as organising thrombus can enhance.
- Diagnosis can generally be made on venography.
