Dural sinus thrombosis (DST) is a potentially fatal neurological condition that can be reversed with early diagnosis and prompt treatment. Non-enhanced CT scan is often the first imaging investigation in patients presenting with acute neurological symptoms; however, its poor sensitivity in detecting DST is a major drawback. Magnetic resonance (MR) imaging offers multiple advantages such as excellent contrast resolution and unenhanced venography possibilities, making it the mainstay in the non-invasive diagnosis of DST. However, physiological variations, evolution of thrombi, and incorrect selection/application of MR techniques can lead to false positive and false negative interpretations impacting patient management and outcome. This article discusses the MR techniques useful to diagnose DST and describes pitfalls, with troubleshooting methods, to ensure an accurate diagnosis. We have used multiple diagrammatic illustrations and MR images to highlight pertinent take-home points and to serve as an easy guide for day-to-day clinical practice.

The Brain

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.

Inherited Thrombophilia

Cerebral venous and dural sinus thrombosis (CVT) is an uncommon disease in the general population, although it is a significant stroke type throughout pregnancy and the puerperium. Studies describing this subtype of CVT are limited. Most pregnancy-associated CVT happen in late pregnancy, or more commonly in the first postpartum weeks, being associated with venous thrombosis outside the nervous system. Case presentation: The current study describes a case of multiple CVT in a 38-year-old woman with multiple risk factors (including severe inherited thrombophilia and being in the puerperium period), presenting mixed transcortical aphasia (a rare type of aphasia) associated with right moderate hemiparesis and intracranial hypertension. The clinical diagnosis of CVT was confirmed by laboratory data and neuroimaging data from head computed tomography, magnetic resonance imaging, and magnetic resonance venography. She was successfully treated with low-molecular-weight heparin (anticoagulation) and osmotic diuretics (mannitol) for increased intracranial pressure and cerebral edema. At discharge, after 15 days of evolution, she presented a partial recovery, with anomic plus aphasia and mild right hemiparesis. Clinical and imaging follow-up was performed at 6 months after discharge; our patient presented normal language and mild right central facial paresis, with chronic left thalamic, caudate nucleus, and internal capsule infarcts and a partial recanalization of the dural sinuses.
