    You can refuse them by changing the settings, however this could impact on the proper functioning of the site. Notice separate entry of the precentral vein C and superior culmen vein black arrow into the Galen. The inferior petrosal sinus receives the internal auditory veins and also veins from the medulla oblongata, pons, and under surface of the cerebellum. Hydrogen 1 magnetic resonance spectroscopy MRS shows a normal N-acetyl aspartate NNA peak and a small lactate peak, suggesting that the functionally impaired neurons are still viable in CVT; these findings also, emphasize the difference between venous and arterial infarcts [ 1 ]. The symptoms related to an underlying otic infections in patients with LS thrombosis are relatively characteristic. The signs and symptoms of this disease take a more indolent form with an isolated abducens nerve palsy and mild chemosis and proptosis [ 12047 ].

    Contemporary brain imaging techniques [angiography, magnetic resonance imaging MRI and magnetic resonance angiography MRA ] allow the diagnosis of benign forms of CVT with minimal, nonspecific symptoms and spontaneous recovery [ 13 ]. The most common symptoms in adults are headache, nausea and vomiting, gait ataxia, neuropsychological symptoms, disturbances of consciousness, hemiparesis that may be bilateral or alternating and seizures. Headache, facial pain and fever can precede the typical syndrome described [ 920 ]. Cavernous sinus thrombosis represents the single CVT which produces a characteristic clinical syndrome which includes: chemosis, conjunctival edema, proptosis and painful complete or partial ophthalmoplegia [ 15920 ]. In this particular image, we can see several arachnoid granulations.

    Hormonal abnormalities may also interfere with normal coagulation mechanisms in males. Nevertheless, the distribution of the parenchymal abnormalities, including diffuse edema, bilaterally infarcts or hemorrhages, predominance of hemorrhagic changes and the presence of a lesion which crosses usual arterial boundaries should always raise the suspicion of CVT [ 1420 ]. Thrombosis of cerebral veins or sinuses causes a progressive increase of venular and capillary pressure. CVT can be caused by multiple predisposing conditions and precipitants. Cerebrospinal fluid is normally absorbed through arachnoids granulations especially into the SSS and LS.

SS runs postero-inferiorly and ultimately joins torcular Cerebral dural sinuses and their tributaries book at the internal occipital protuberance [ 9 ]. The most frequent symptoms are headache, papilledema, seizures, motor, sensory or language deficits, altered mental status and decreased consciousness.

The gender-specific risk factors — pregnancy, postpartum state, oral contraceptive OC use and the hormone replacement therapy — are the most frequent risk factors in women with CVT, they being responsible for the marked feminine preference of this condition [ 4618 ].

D The veins of the superior cerebellar peducle brachial tributaries [D] of the precentral vein Cerebral dural sinuses and their tributaries book are also connected to the lateral mesencephalic vein Ha. Bilateral motor signs may also occur as a consequence of the bi-hemispheric injuries caused by the SSS thrombosis [ 11420 ].

The limited drainage that occurs due to CVT and resulting increased venous pressure, often causes fluid to back up into the brain, causing vasogenic edema. Cavernous sinus thrombosis usually has an infectious cause. It is important to mention that normal D-dimer level does not exclude the diagnosis, particularly in patients who present with isolated headache and in case of prolonged duration of symptoms i.

The opposite finding enlarged ventricles does not exclude the diagnosis considering that it can be associated with cerebellar vein thrombosis [ 120 ]. However, if a normal result is obtain at the time of clinical presentation, the antiphospholipid antibody syndrome is ruled out [ 14 ].

The symptoms related to an underlying otic infections in patients with LS thrombosis are relatively characteristic. Several methods can assess venous or dural sinus flow: two-dimensional time-of-flight 2D-TOFthree dimensional time-of-flight 3DTOF and phase contrast; contrast enhancement MR venography with elliptic centric ordering is a newer technique which allows superior assessment of smaller venous channels [ 1520 ].

These are veins that run from the scalp, cross the skull itself, and can empty blood into dural venous sinus as we see here.
