This prevents blood from draining out of the brain. Cerebral venous sinus thrombosis This involves the presence of thrombosis in the deep cerebral veins. Internal jugular vein thrombosis (IJVT) is an uncommon, potentially fatal, condition. Her physical examination revealed livedo reticularis on her limbs. Sigmoid sinus thrombosis can occur in the presence or absence of other intracranial or intratemporal complications of otitis media. Case Presentation. She had no contributory family history or oral contraceptive use. Types of Venous Sinus Thrombosis. Immunologic abnormalities, including the presence of circulating antiphospholipid antibodies, can also serve as risk factors. Septic transverse or. 1-5 Although neurological symptoms associated with cerebrovascular congestion leading to a diagnosis of sinus thrombosis have been reported, 4, 6 most cases are incidentally diagnosed on routine postoperative imaging. Anticoagulation with dose-adjusted heparin is reported to be beneficial in patients with aseptic venous sinus thrombosis and is used in the treatment of septic venous sinus thrombosis when patients are worsening despite antimicrobial therapy and intravenous fluids. Other recognized causes include malignancy, pregnancy, hormonal contraceptive therapy, and coagulation disorders [1]. Dural Venous Sinus Thrombosis – This involves the formation of clot on the superficial veins in the dura mater. Increased density (CT) or abnormal signal intensity (MR) in affected dural sinus of posterior fossa, Thrombophlebitis most commonly starts at transverse-sigmoid confluence, DST may involve ≥ 1 of following posterior fossa sinuses: Torcular Herophili, transverse sinus (TS) ± vein of Labbé, sigmoid sinus (SS), jugular bulb, In acute thrombosis, affected sinus may be enlarged, Caveat : Transverse sinus size typically asymmetric from side to side in individual, Conforms to shape of dural sinus affected, Fusiform enlargement of venous structure acutely, Important for distinguishing DST from arachnoid granulation (focal filling defect), ↑ density thrombus in affected dural sinus, Dense triangle of thrombus, δ sign, if sinus seen in cross section, Phrase used mainly to describe sagittal sinus thrombosis, Sagittal CT reconstruction of TS or coronal reconstruction of SS could show δ sign, Parenchymal venous infarction may be associated (∼ 1/3 of cases), Parenchymal hypodensity (edema ± infarction), Temporal or occipital lobe location with TS thrombosis, Cerebellar hemisphere location with distal TS & SS thrombosis, Cortical/subcortical hemorrhages (may be petechial), Reverse or empty δ sign, enhancing dural leaves surrounding less dense thrombus (25% of cases), Filling defect in TS ± SS; may extend into jugular bulb or vein, Shaggy, dilated, irregular cortical veins (collateral channels), CECT alone unreliable for diagnosis of DST extent (high-density clot may appear like patent enhancing sinus), When performed per arterial protocol, enhancement phase too early to evaluate venous sinuses, Hyperdense sinus could potentially be confused with venous contrast, 10-15 second delay beyond CTA image acquisition allowing venous timing for CT venogram, Filling defect in dural venous sinus with surrounding dural enhancement, Acute DST: Absent flow void with isointense clot (similar to gray matter), Subacute DST: Hyperintense clot (methemoglobin), Acute DST: Hypointense clot (deoxyhemoglobin), Additional findings if parenchymal infarction present, Gyral swelling, sulcal effacement in temporal lobe, Hyperintense if venous infarction is acute, May be petechial (many small cortical foci), ↑ signal & swelling in adjacent brain parenchyma if associated acute infarction occurs, Profound hypointense signal or blooming on T2* sequences with acute or subacute thrombosis, May be difficult to discern against bone, air (in adjacent temporal bone), Chronic thrombus is isointense to hyperintense on GRE sequences, Parenchymal hemorrhage in venous infarct ↓ signal in acute stage, Acute & subacute clot may demonstrate restricted diffusion, Acute parenchymal venous infarct shows restricted diffusion, Parenchymal DWI abnormalities are more likely reversible compared to arterial ischemic insults, Filling defect may nearly completely fill dural sinuses, Peripheral enhancement may be reactive dura or residual flow around clot, Chronic DST may enhance intensely & should be correlated with MRV findings, Irregular enhancing venous channels may be seen with incomplete recanalization; enhancement within recanalized clot may mimic normal sinus enhancement, Associated parenchymal venous infarction may show patchy enhancement, Lack of flow-related signal in TS-SS, ± jugular bulb, Complete lack of flow in affected dural sinuses, Central filling defect with surrounding contrast, Arteriovenous transit time often delayed in affected area, MR with MRV is best single imaging exam for DST, Almost all MR sequences show signal abnormality in dural sinuses, Complications (venous infarct, hemorrhage) easily identified, Susceptibility weighted imaging (SWI) may prove to be useful technique, CT/CTV diagnoses DST but less sensitive for complications, If cross-sectional imaging equivocal, consider conventional angiography, Coronal & sagittal CTV reconstructions ± MRV sequences very helpful for TS & SS thrombosis evaluation, Contrast-enhanced MRV decreases false-positive DST in small but patent dural sinus, Use MRV with multiple encoding gradients to distinguish physiological flow asymmetry from thrombus, IMAN NASERI MD, STEVEN E. SOBOL MD, in Pediatric Otolaryngology, 2007, Infections involving the middle ear and mastoid may result in a septic thrombus of the sigmoid sinus. 2a). Direct injury to any of the intracranial sinuses can create a thrombus, or blood clot, as can trauma to proximal blood vessels. Coronal CECT in a patient on hemodialysis with prior right IJV catheter and subsequent left IJV hemodialysis catheter shows that the patient presented with bilateral IJV thrombosis. 7-3B and C).74,75 In the young child, transcranial Doppler ultrasonography is an alternative to CT and MRI and is valuable in the evaluation of cerebral venous thrombosis.76 This noninvasive test is particularly useful in evaluating interval changes when assessing flow and recanalization of the involved sigmoid sinus. The randomized, double-blind RE-COVER trial reported that a fixed dose of the direct thrombin inhibitor dabigatran is as effective as warfarin, with a similar safety profile, for the treatment of acute venous thromboembolism. Sigmoid sinus involvement is rare in isolation but can cause mastoid pain and, very rarely, lower cranial neuropathies. Our patient had IJVT related to an inherited coagulopathy, but no trigger factors were identified. If the symptoms of cavernous sinus thrombosis were caused by an infection spreading from a boil or sinusitis, it may be necessary to drain away pus from that site. 39-6). Her INR was adjusted to 2.5–3.0. Axial T2 FS MR reveals the right thrombosed IJV to be of heterogeneous signal intensity and the adjacent deep fat to be hyperintense. Both partial IJV thrombosis and adjacent abscess were present in this IV drug user. The authors declare that there is no conflict of interests regarding the publication of this paper. Patients with septic thrombosis of the superior sagittal sinus have headache, nausea and vomiting, weakness of the lower extremities with bilateral Babinski signs, focal or generalized seizures, and an alteration in the level of consciousness. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Hypo- or hyperesthesia of the ophthalmic and maxillary divisions of the fifth cranial nerve and a decreased corneal reflex may be detected. The sigmoid sinus is a large vein located inside the bone behind the ear, which is … Many children refuse to speak when dysarthric. In the patient described here, bone wax was used to stop bleeding and may have caused granuloma formation followed by thrombosis of the dural sinuses. Imaging of the brain, initially computed tomography, followed by magnetic resonance venography, confirmed a diagnosis of sigmoid sinus thrombosis with associated venous infarction. Embolization of the thrombus can cause distal disease. 2, 3, 7, 8 Although postoperative sinus thrombosis … The classic presence of a “picket fence” fever has not generally been seen since the advent of antibiotics. Note surrounding inflammation and fat stranding supporting acuity. The recent availability of new oral anticoagulants provides alternative options. Extensive T2 hyperintense edema and inflammation are visible in the surrounding soft tissues . Meningitis, epidural empyema, brain abscess, and sigmoid sinus thrombosis can develop as complications of acute or chronic ear or mastoid infection. Transverse sinus and sigmoid sinus thrombosis causes headache and vomiting with or without fever and features of raised intracranial pressure. Introduction. Internal jugular vein thrombosis (IJVT) is a rare condition associated with malignancy, coagulopathy, and trauma. The oculomotor nerve (III), trochlear nerve (IV), abducens nerve (VI), and ophthalmic and maxillary branches of the trigeminal nerve (V) all pass through the cavernous sinus; therefore, the classic signs of a septic cavernous sinus thrombosis are ptosis, proptosis, and extraocular dysmotility due to deficits of cranial nerves III, IV, and VI. Onset frequently follows a febrile illness; the child is generally afebrile when ataxia begins. Tympanocentesis should be performed for bacterial culture to aid in diagnosis and management choices. Needle fragment is seen laterally . Since the introduction of antibiotics, conservative medical treatment has evolved as the mainstay in the management of sigmoid sinus thrombophlebitis. Özge Altıntaş, Azize Esra Gürsoy, Gözde Baran, Elnur Mehdi, Talip Asil, "Bilateral Jugular Vein and Sigmoid Sinus Thrombosis Related to an Inherited Coagulopathy: An Unusual Presentation", Case Reports in Vascular Medicine, vol. In the 1840s Wilhelm Griesinger, a German psychiatrist and anatomic pathologist, coined the term Griesinger's sign, which is swelling and tenderness over the mastoid process caused by thrombosis of the transverse sinus. The third type of thrombosis is the septic dural sinus thrombosis, seen after otitis media or mastoiditis and is located in the transverse and sigmoid sinus (Amirmaidi, 1988; Kolenda et al., 1997; Kuczkowski and Mikaszewski, 2001). In Diagnostic Imaging: Head and Neck (Third Edition), 2017, Asymmetric low to intermediate signal in PA, High signal within marrow &/or air cells of petromastoid complex, High signal focus in PA where focal abscess may occur, Avidly enhancing adjacent meningeal thickening, Skull base osteomyelitis: Enhancing marrow in clivus & PA, Thickened, enhancing Meckel cave & cavernous sinus, Enhancing cranial nerves (especially CNV, CNVI), Petrous ± cavernous internal carotid artery (ICA) spasm, Severe lesions can involve adjacent skull base arteries, Advanced disease may cause dural venous sinus thrombophlebitis, Cavernous-petrosal or sigmoid sinus-jugular bulb thrombosis possible. Early anticoagulant treatment is crucial to limit thrombus extension. Occasionally good clinical results have been reported with catheter-directed urokinase therapy and intrathrombus infusion of recombinant tissue plasminogen activator for aseptic venous sinus thrombosis that clinically progresses while on anticoagulation, but there has not been enough experience with these therapies for septic venous sinus thrombosis to make recommendations regarding their use. Mastoiditis is known to cause sigmoid sinus thrombosis.25 Our patient developed spontaneous posterior fossa epidural haematoma secondary to sigmoid sinus thrombosis which was due to mastoiditis. Hematomas are centrally hyperintense and have a hypointense halo on T1-weighted images (Fig. The pain and swelling resolved over the course of a week, and her symptoms did not recur. Cortical dehiscence is present medially. –Thrombosis of the deep venous system –Right hemisphere hemorrhage –Posterior fossa lesions. Axial T-bone CT shows middle ear and the mastoid air cells a tubular collection.
