Hypointense signals were detected in the area of the right cavernous sinus
and Meckel's cave on short tau inversion recovery (STIR) and T2 MRI weighted images (Figs.
A follow-up MRI performed after three months in patient 5 showed decreased signal intensity and enhancement of the affected cavernous sinus
(Figure 1, 2).
Odontogenic maxillofacial infections, if untreated, may progress to involve deep neck space infection, which can spread upward to brain causing brain abscess, meningitis and cavernous sinus
These adenomas lead to erosion in the scull base bones by extending to the sides (subtemporal or prepontine extension) in addition to cavernous sinus
and suprasellar extension and may show sphenoid sinus involvement.
Othello syndrome in a patient with right orbitofrontal lobe cavernous sinus
Radiological investigation in the form of MRI brain showed the lesion leading to expansion of left cavernous sinus
Magnetic resonance venography (MRV) demonstrated right sigmoid and transverse sinus thrombosis, right proximal internal jugular vein thrombosis, and bilateral cavernous sinus
thrombosis (figure 2).
The etiology of THS has been attributed to nonspecific inflammatory process of uncertain cause that has been confined to the septa and wall of the cavernous sinus
described as infiltration of lymphocyte and plasma cell, formation of giant cell granulomas, and fibroblast proliferation [1,2].
2,4) Orbital complications of frontal sinusitis comprise preseptal or orbital cellulitis, subperiosteal abscess, and cavernous sinus
The vertebral veins in turn communicate superiorly with the pterygoid plexus cavernous sinus
and superior portion of the pharyngeal plexus hence providing a pathway for metastasis to the tongue.
This edition has new cranial CT sequences of the axial and coronal temporal bone; an expanded MR imaging section with new 3-Tesla MR images of the temporal lobe and hippocampus, basilar artery, cranial nerves, cavernous sinus
, and other areas; and new arterial MR angiography sequences of the neck and additional larynx images.
The department has also introduced a programme of advanced stereotactic radiosurgery treatments using the TrueBeam system for cranial conditions such as acoustic neuromas, brain metastasis, and cavernous sinus
