Venous sinus thrombosis is an uncommon cause of stroke. Magnetic resonance imaging and magnetic resonance venography are sensitive and specific non-invasive tools for the diagnosis. This is a report of patient who presented with atrial fibrillation and heart failure. The course of the disease was complicated by left-sided transverse sinus thrombosis leading to hemorrhagic stroke. There was normal looking transverse sinus upon contrast injection with gadolinium despite the lack of flow on magnetic resonance venography. It is postulate that this apparently normal transverse sinus appearance on post gadolinium T1-weighted imaging was a result of thrombus enhancement in the acute stage of the venous occlusion. This finding could mislead the diagnosis if it was read in isolation without the confirmation of the occlusion in magnetic resonance venography.

Abstract BACKGROUND: Although the majority of patients with cerebral venous sinus thrombosis (CVST) obtain an optimistic clinical outcome after heparin or warfarin treatment, there remains a subgroup of patients who do not respond to conventional anticoagulation treatment. These patients, especially younger people, as documented by hospital-based studies, have a high morbidity and mortality rate. OBJECTIVE: To verify the safety and efficacy of a dual mechanical thrombectomy with thrombolysis treatment modality option in patients with severe CVST. METHODS: Fifty-two patients diagnosed with CVST were enrolled and treated with mechanical thrombectomy combined with thrombolysis. Patients underwent urokinase 100 to 1500 × 103 IU intravenous sinus injection via a jugular catheter after confirming diagnoses of CVST by using either magnetic resonance imaging/magnetic resonance venography or digital subtract angiography. Information obtained on the patients included recanalization status of venous sinuses as evaluated by magnetic resonance venography or digital subtract angiography at admission, during operation, and at 3- and 6-month follow-up after treatment. RESULTS: The percentage of patients that showed complete and partial recanalization were 87% and 6%, respectively, after mechanical thrombectomy combined with thrombolysis treatment; 8% of the patients showed no recanalization. The modified Rankin Scale scores were 1.0 ± 0.9, 0.85 ± 0.63, and 0.37 ± 0.53 for discharge, and 3- and 6-month follow-up, respectively. A total of 6 patients died despite receiving aggressive treatment. No cases of relapse occurred after 3 to 6 months of follow-up. CONCLUSION: Thrombectomy combined with thrombolysis is a safe and valid treatment modality to use in severe CVST cases or in intractable patients that have shown no adequate response to antithrombotic drugs.

Objective The relation between venous morphology and venous function in postthrombotic syndrome is poorly understood. The aim of this study was to compare obstruction and collateralization as seen with magnetic resonance venography with variables of venous occlusion plethysmography in patients with postthrombotic syndrome. Methods Medical records, magnetic resonance venography and venous occlusion plethysmography data were analyzed in 28 patients (33 legs). Magnetic resonance venography images were scored for degree of obstruction and collateralization in segments of pelvic and abdominal veins and correlated to venous occlusion plethysmography data. Results Obstruction of the inferior vena cava correlated with an overall increase of collaterals ( p < 0.001). The summary scores of collaterals or obstructions did not correlate with venous occlusion plethysmography variables. Relative expelled volume at 4 s correlated inversely with obstruction of the inferior vena cava ( p = 0.045) and vertebral collateralization ( p = 0.033). Conclusions Modest correlations were found between magnetic resonance venography scores and venous occlusion plethysmography variables. Prospective studies with refined scoring and magnetic resonance venography techniques may increase our knowledge further.

Magnetic Resonance Imaging (MRI) study of the brain and Magnetic Resonance Venography (MRV) offer major advantages in evaluating patients suspected of having dural sinus thrombosis. Since 2002, we have examined 49 patients in our department with definite dural sinus thrombosis. MRI and MRV revealed the thrombosis of the dural sinus, and the underlying cause in most patients. There is consensus in the literature that MRI scanning in combination with MRV is the method of choice for evaluating dural sinus thrombosis, and this is also the end result of our study. We also compared the 3D-TOF technique and 2D-PC technique for MRV examination and found that the 3D-TOF technique is clearly the method of choice.

ABSTRACTCerebral venous sinus thrombosis is a rare form of stroke caused by thrombosis in venous sinuses of the brain. In this study, we reported on a patient with venous sinus thrombosis and brucellosis who presented with uncontrolled seizure despite being treated with anti-epileptic drugs at high doses. The case was a 33-year-old woman with a history of controlled complex partial seizure who presented with headache, asthenia, and uncontrolled seizure for one month. She was febrile and a brain CT scan indicated hemorrhagic focus in the left posterior parietal and the temporal lobe. Magnetic resonance imaging and magnetic resonance venography also proved venous sinus thrombosis in the left transverse sinus. Besides [In addition], a laboratory assessment confirmed brucellosis. Following the treatment with anti-coagulant, anti-brucellosis, and anti-epileptic agents, the patient was discharged in good condition with medical orders. Clinical suspicion and accurate evaluation of a patient′s history is the most important clue in diagnosis and treatment of brucellosis and cerebral venous sinus thrombosis, especially in uncontrolled seizure in patients who had previously been under control.

BACKGROUND: Cerebral venous sinus thrombosis (CVST) is a scarce disease with poor prognosis and its diagnosis often challenges physicians due to nonspecific symptoms and widespread clinical manifestations. AIM: To investigate the findings of magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) of patients with CVST diagnosis in Ali Ebne Abitaleb Hospital in Zahedan during 2013–2016 and to evaluate imaging pitfalls involving in late diagnosis, complications, and even death. METHODS: This retrospective descriptive study was done on 57 patients with confirmed CVST during 2013–2016 in Ali Ebne Abitaleb Hospital in Southeast of Iran (Zahedan). The MRI and MRV findings and related diagnostic pitfalls were evaluated. Twenty-one patients are pediatrics and 33 patients are adults. RESULTS: Of 57 patients, evidences of cerebral edema were found in 33 patients, among whom 2 patients showed parenchymal edema (cerebral edema) without infarction, and 31 patients exhibited parenchymal edema with infarction. The frequency of involvement in descending order was as followed; transverse sinus (96.49%), sigmoid sinus (49.12%), superior sagittal sinus (29.82%), jugular vein (19.29%), internal cerebral veins (7.01%), straight sinus (5.2%), and cortical veins (5.2%). Diagnostic pitfalls were also found in 8 patients. Seven patients exhibited acute and subacute thrombosis mimicked normal sinus flow void in T2-weighted images. No filling defect was seen on gadolinium-enhanced T1-weighted image in the other patient due to the sub-acute phase of thrombosis. CONCLUSION: The delayed diagnosis of CVST originating from nonspecific clinical features and diagnostic imaging pitfalls can result in poor outcomes in patients. To prevent the diagnostic pitfalls, the clinician should give a brief history and clinical data and radiologist(s) should interpret the findings in addition to the use of advanced MR sequences.
