Can MRI detect cavernous sinus thrombosis?

Cavernous sinus thrombosis is a clinical diagnosis. MRI with contrast is the imaging modality of choice to confirm its presence and to differentiate it from alternatives such as orbital cellulitis, which may have a similar clinical presentation.

What somatosensory symptoms are associated with a cavernous sinus aneurysm?

History. The signs and symptoms frequently found in patients with cavernous sinus lesions include visual loss, proptosis, ocular and conjunctival congestion, elevation of ocular pressure, ophthalmoplegia, and pain.

What nerves go through the cavernous sinus?

The nerves of the cavernous sinus are the oculomotor nerve (CN III), trochlear nerve (CN IV), ophthalmic nerve (V1), maxillary nerve (V2), abducens nerve (CN VI), and the sympathetic plexus around the internal carotid artery.

Why is the cavernous sinus of clinical importance?

The cavernous sinus is the only site in the body where an artery (internal carotid) passes completely through a venous structure. This is thought to allow for heat exchange between the warm arterial blood and cooler venous circulation. Fig 2 – Coronal section demonstrating the contents of the right cavernous sinus.

How do you test for cavernous sinus thrombosis?

Tests for Cavernous Sinus Thrombosis Doctors may order brain scans, including CT and MRI scans, to look for cavernous sinus thrombosis. They may also test blood or spinal fluid to check for signs of infection.

What are the signs of cavernous sinus thrombosis?

What are the symptoms of cavernous sinus thrombosis?

Which teeth can cause cavernous sinus thrombosis?

The cavernous sinuses are cavities located at the base of the skull. A cavernous sinus thrombosis is usually a complication of an infection of the central face, paranasal sinuses, bacteremia, trauma, and infections of the ear or maxillary (upper) teeth.

Is the cavernous sinus part of the brain?

The cavernous sinuses are one of several drainage pathways for the brain that sits in the middle. In addition to receiving venous drainage from the brain, it also receives tributaries from parts of the face.

What might be one of the earliest symptoms of cavernous sinus thrombosis?

What nerve is first affected in cavernous sinus thrombosis?

Lateral gaze palsy (isolated cranial nerve VI) is usually seen first since CN VI lies freely within the sinus in contrast to CN III and IV, which lie within the lateral walls of the sinus.
